--- The GNU General Public License, Version 1, February 1989 ---
This software is Copyright (c) 2009, 2014, 2025-2026 by Message Systems, Inc.
This is free software, licensed under:
The GNU General Public License, Version 1, February 1989
GNU GENERAL PUBLIC LICENSE
Version 1, February 1989
Copyright (C) 1989 Free Software Foundation, Inc.
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The license agreements of most software companies try to keep users
at the mercy of those companies. By contrast, our General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. The
General Public License applies to the Free Software Foundation's
software and to any other program whose authors commit to using it.
You can use it for your programs, too.
When we speak of free software, we are referring to freedom, not
price. Specifically, the General Public License is designed to make
sure that you have the freedom to give away or sell copies of free
software, that you receive source code or can get it if you want it,
that you can change the software or use pieces of it in new free
programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of a such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must tell them their rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any program or other work which
contains a notice placed by the copyright holder saying it may be
distributed under the terms of this General Public License. The
"Program", below, refers to any such program or work, and a "work based
on the Program" means either the Program or any work containing the
Program or a portion of it, either verbatim or with modifications. Each
licensee is addressed as "you".
1. You may copy and distribute verbatim copies of the Program's source
code as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and
disclaimer of warranty; keep intact all the notices that refer to this
General Public License and to the absence of any warranty; and give any
other recipients of the Program a copy of this General Public License
along with the Program. You may charge a fee for the physical act of
transferring a copy.
2. You may modify your copy or copies of the Program or any portion of
it, and copy and distribute such modifications under the terms of Paragraph
1 above, provided that you also do the following:
a) cause the modified files to carry prominent notices stating that
you changed the files and the date of any change; and
b) cause the whole of any work that you distribute or publish, that
in whole or in part contains the Program or any part thereof, either
with or without modifications, to be licensed at no charge to all
third parties under the terms of this General Public License (except
that you may choose to grant warranty protection to some or all
third parties, at your option).
c) If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use
in the simplest and most usual way, to print or display an
announcement including an appropriate copyright notice and a notice
that there is no warranty (or else, saying that you provide a
warranty) and that users may redistribute the program under these
conditions, and telling the user how to view a copy of this General
Public License.
d) You may charge a fee for the physical act of transferring a
copy, and you may at your option offer warranty protection in
exchange for a fee.
Mere aggregation of another independent work with the Program (or its
derivative) on a volume of a storage or distribution medium does not bring
the other work under the scope of these terms.
3. You may copy and distribute the Program (or a portion or derivative of
it, under Paragraph 2) in object code or executable form under the terms of
Paragraphs 1 and 2 above provided that you also do one of the following:
a) accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of
Paragraphs 1 and 2 above; or,
b) accompany it with a written offer, valid for at least three
years, to give any third party free (except for a nominal charge
for the cost of distribution) a complete machine-readable copy of the
corresponding source code, to be distributed under the terms of
Paragraphs 1 and 2 above; or,
c) accompany it with the information you received as to where the
corresponding source code may be obtained. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form alone.)
Source code for a work means the preferred form of the work for making
modifications to it. For an executable file, complete source code means
all the source code for all modules it contains; but, as a special
exception, it need not include source code for modules which are standard
libraries that accompany the operating system on which the executable
file runs, or for standard header files or definitions files that
accompany that operating system.
4. You may not copy, modify, sublicense, distribute or transfer the
Program except as expressly provided under this General Public License.
Any attempt otherwise to copy, modify, sublicense, distribute or transfer
the Program is void, and will automatically terminate your rights to use
the Program under this License. However, parties who have received
copies, or rights to use copies, from you under this General Public
License will not have their licenses terminated so long as such parties
remain in full compliance.
5. By copying, distributing or modifying the Program (or any work based
on the Program) you indicate your acceptance of this license to do so,
and all its terms and conditions.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the original
licensor to copy, distribute or modify the Program subject to these
terms and conditions. You may not impose any further restrictions on the
recipients' exercise of the rights granted herein.
7. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of the license which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
the license, you may choose any version ever published by the Free Software
Foundation.
8. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to humanity, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.
To do so, attach the following notices to the program. It is safest to
attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
Copyright (C) 19yy
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 1, or (at your option)
any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, see .
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19xx name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the
appropriate parts of the General Public License. Of course, the
commands you use may be called something other than `show w' and `show
c'; they could even be mouse-clicks or menu items--whatever suits your
program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
program `Gnomovision' (a program to direct compilers to make passes
at assemblers) written by James Hacker.

--- The Perl Artistic License 1.0 ---
This software is Copyright (c) 2009, 2014, 2025-2026 by Message Systems, Inc.
This is free software, licensed under:
The Perl Artistic License 1.0
The "Artistic License"
Preamble
The intent of this document is to state the conditions under which a
Package may be copied, such that the Copyright Holder maintains some
semblance of artistic control over the development of the package,
while giving the users of the package the right to use and distribute
the Package in a more-or-less customary fashion, plus the right to make
reasonable modifications.
Definitions:
"Package" refers to the collection of files distributed by the
Copyright Holder, and derivatives of that collection of files
created through textual modification.
"Standard Version" refers to such a Package if it has not been
modified, or has been modified in accordance with the wishes
of the Copyright Holder as specified below.
"Copyright Holder" is whoever is named in the copyright or
copyrights for the package.
"You" is you, if you're thinking about copying or distributing
this Package.
"Reasonable copying fee" is whatever you can justify on the
basis of media cost, duplication charges, time of people involved,
and so on. (You will not be required to justify it to the
Copyright Holder, but only to the computing community at large
as a market that must bear the fee.)
"Freely Available" means that no fee is charged for the item
itself, though there may be fees involved in handling the item.
It also means that recipients of the item may redistribute it
under the same conditions they received it.
1. You may make and give away verbatim copies of the source form of the
Standard Version of this Package without restriction, provided that you
duplicate all of the original copyright notices and associated disclaimers.
2. You may apply bug fixes, portability fixes and other modifications
derived from the Public Domain or from the Copyright Holder. A Package
modified in such a way shall still be considered the Standard Version.
3. You may otherwise modify your copy of this Package in any way, provided
that you insert a prominent notice in each changed file stating how and
when you changed that file, and provided that you do at least ONE of the
following:
a) place your modifications in the Public Domain or otherwise make them
Freely Available, such as by posting said modifications to Usenet or
an equivalent medium, or placing the modifications on a major archive
site such as uunet.uu.net, or by allowing the Copyright Holder to include
your modifications in the Standard Version of the Package.
b) use the modified Package only within your corporation or organization.
c) rename any non-standard executables so the names do not conflict
with standard executables, which must also be provided, and provide
a separate manual page for each non-standard executable that clearly
documents how it differs from the Standard Version.
d) make other distribution arrangements with the Copyright Holder.
4. You may distribute the programs of this Package in object code or
executable form, provided that you do at least ONE of the following:
a) distribute a Standard Version of the executables and library files,
together with instructions (in the manual page or equivalent) on where
to get the Standard Version.
b) accompany the distribution with the machine-readable source of
the Package with your modifications.
c) give non-standard executables non-standard names, and clearly
document the differences in manual pages (or equivalent), together
with instructions on where to get the Standard Version.
d) make other distribution arrangements with the Copyright Holder.
5. You may charge a reasonable copying fee for any distribution of this
Package. You may charge any fee you choose for support of this
Package. You may not charge a fee for this Package itself. However,
you may distribute this Package in aggregate with other (possibly
commercial) programs as part of a larger (possibly commercial) software
distribution provided that you do not advertise this Package as a
product of your own. You may embed this Package's interpreter within
an executable of yours (by linking); this shall be construed as a mere
form of aggregation, provided that the complete Standard Version of the
interpreter is so embedded.
6. The scripts and library files supplied as input to or produced as
output from the programs of this Package do not automatically fall
under the copyright of this Package, but belong to whoever generated
them, and may be sold commercially, and may be aggregated with this
Package. If such scripts or library files are aggregated with this
Package via the so-called "undump" or "unexec" methods of producing a
binary executable image, then distribution of such an image shall
neither be construed as a distribution of this Package nor shall it
fall under the restrictions of Paragraphs 3 and 4, provided that you do
not represent such an executable image as a Standard Version of this
Package.
7. C subroutines (or comparably compiled subroutines in other
languages) supplied by you and linked into this Package in order to
emulate subroutines and variables of the language defined by this
Package shall not be considered part of this Package, but are the
equivalent of input as in Paragraph 6, provided these subroutines do
not change the language in any way that would cause it to fail the
regression tests for the language.
8. Aggregation of this Package with a commercial distribution is always
permitted provided that the use of this Package is embedded; that is,
when no overt attempt is made to make this Package's interfaces visible
to the end user of the commercial distribution. Such use shall not be
construed as a distribution of this Package.
9. The name of the Copyright Holder may not be used to endorse or promote
products derived from this software without specific prior written permission.
10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

Net::CIDR::Set - Manipulate sets of IP addresses
# SYNOPSIS
```perl
use Net::CIDR::Set;
my $priv = Net::CIDR::Set->new( '10.0.0.0/8', '172.16.0.0/12',
'192.168.0.0/16' );
for my $ip ( @addr ) {
if ( $priv->contains( $ip ) ) {
print "$ip is private\n";
}
}
```
# DESCRIPTION
`Net::CIDR::Set` represents sets of IP addresses and allows standard
set operations (union, intersection, membership test etc) to be
performed on them.
In spite of the name it can work with sets consisting of arbitrary
ranges of IP addresses - not just CIDR blocks.
Both IPv4 and IPv6 addresses are handled - but they may not be mixed in
the same set. You may explicitly set the personality of a set:
```perl
my $ip4set = Net::CIDR::Set->new({ type => 'ipv4 }, '10.0.0.0/8');
```
Normally this isn't necessary - the set will guess its personality from
the first data that is added to it.

Report security issues via the project
[Security Advisories](https://github.com/robrwo/perl-Net-CIDR-Set/security/advisories).
This is the Security Policy for Net-CIDR-Set.
The latest version of the Security Policy can be found in the
[git repository for Net-CIDR-Set](https://github.com/robrwo/perl-Net-CIDR-Set).
This text is based on the CPAN Security Group's Guidelines for Adding
a Security Policy to Perl Distributions (version 1.3.0)
https://security.metacpan.org/docs/guides/security-policy-for-authors.html
# How to Report a Security Vulnerability
Security vulnerabilities can be reported to the current Net-CIDR-Set
maintainers via the project
[Security Advisories](https://github.com/robrwo/perl-Net-CIDR-Set/security/advisories).
Please include as many details as possible, including code samples
or test cases, so that we can reproduce the issue. Check that your
report does not expose any sensitive data, such as passwords,
tokens, or personal information.
If you would like any help with triaging the issue, or if the issue
is being actively exploited, please copy the report to the CPAN
Security Group (CPANSec) at .
Please *do not* use the public issue reporting system on RT or
GitHub issues for reporting security vulnerabilities.
Please do not disclose the security vulnerability in public forums
until past any proposed date for public disclosure, or it has been
made public by the maintainers or CPANSec. That includes patches or
pull requests.
For more information, see
[Report a Security Issue](https://security.metacpan.org/docs/report.html)
on the CPANSec website.
## Response to Reports
The maintainer(s) aim to acknowledge your security report as soon as
possible. However, this project is maintained by a single person in
their spare time, and they cannot guarantee a rapid response. If you
have not received a response from them within 2 weeks, then
please send a reminder to them and copy the report to CPANSec at
.
Please note that the initial response to your report will be an
acknowledgement, with a possible query for more information. It
will not necessarily include any fixes for the issue.
The project maintainer(s) may forward this issue to the security
contacts for other projects where we believe it is relevant. This
may include embedded libraries, system libraries, prerequisite
modules or downstream software that uses this software.
They may also forward this issue to CPANSec.
# Which Software This Policy Applies To
Any security vulnerabilities in Net-CIDR-Set are covered by this policy.
Security vulnerabilities in versions of any libraries that are
included in Net-CIDR-Set are also covered by this policy.
Security vulnerabilities are considered anything that allows users
to execute unauthorised code, access unauthorised resources, or to
have an adverse impact on accessibility or performance of a system.
Security vulnerabilities in upstream software (prerequisite modules
or system libraries, or in Perl), are not covered by this policy
unless they affect Net-CIDR-Set, or Net-CIDR-Set can
be used to exploit vulnerabilities in them.
Security vulnerabilities in downstream software (any software that
uses Net-CIDR-Set, or plugins to it that are not included with the
Net-CIDR-Set distribution) are not covered by this policy.
## Supported Versions of Net-CIDR-Set
The maintainer(s) will only commit to releasing security fixes for
the latest version of Net-CIDR-Set.
Note that the Net-CIDR-Set project only supports major versions of Perl
released in the past 10 years, even though Net-CIDR-Set will run on
older versions of Perl. If a security fix requires us to increase
the minimum version of Perl that is supported, then we may do so.
# Installation and Usage Issues
The distribution metadata specifies minimum versions of
prerequisites that are required for Net-CIDR-Set to work. However, some
of these prerequisites may have security vulnerabilities, and you
should ensure that you are using up-to-date versions of these
prerequisites.
Where security vulnerabilities are known, the metadata may indicate
newer versions as recommended.
## Usage
Please see the software documentation for further information.

Thank you for considering contributing to Net-CIDR-Set.
There are multiple ways that you can help with this project.
Any contributions (bug reports, feature requests, security issues, or patches)
must cite any tools which generated the reports or code, and any software that
the code is based on.
Contributions must not include content generated by large language models
(LLMs) or other probabilistic tools, including but not limited to Anthropic,
Copilot or ChatGPT. This policy covers code, documentation, pull requests,
issues, comments, and any other contributions to this project.
See [AI Contributions](#ai-contributions) below for more more details.
## Report Bugs and Submit Feature Requests
Please report any bugs or feature requests on the bugtracker website
.
When submitting a bug or request, please include a test-file or a patch to an
existing test-file that illustrates the bug or desired feature.
Using the bugtracker is preferable to emailing the maintainer, as identified
in the AUTHOR section of the POD. But if you are unable to use the
bugtracker, then you may email the current maintainer,
Robert Rothenberg .
### Reporting Security Vulnerabilities
Security issues should not be reported on the bugtracker website. Please see
`SECURITY.md` for instructions how to report security vulnerabilities.
## Submitting Patches
The source code is available via GitHub at
.
Patches should be based on a recent fork of the `main` branch.
This distribution is managed with [Dist::Zilla](https://dzil.org/). This
means that many of the usual files you might expect are not in the repository,
but are generated at release time, as is much of the documentation. Some
generated files are kept in the repository as a convenience
(e.g. `Makefile.PL` or `cpanfile`).
Generally, **you do not need Dist::Zilla to contribute patches**. You do need
Dist::Zilla to create a tarball.
See [Installing and using Dist::Zilla](#installing-and-using-distzilla) below
for guidance.
### Getting dependencies
If you have [App::cpanminus](https://metacpan.org/pod/App::cpanminus) 1.6 or
later installed, you can use `cpanm` to satisfy dependencies like this:
$ cpanm --installdeps .
Otherwise, look for either a `Makefile.PL` or `cpanfile` file for a list of
dependencies to satisfy.
### Running tests
You can run tests directly using the `prove` tool:
$ prove -l
$ prove -lv t/some_test_file.t
For most cases, `prove` is entirely sufficient to test any patches you have.
### Code style and tidying
Please try to match any existing coding style. If there is a `.perltidyrc`
file, please install [Perl::Tidy](https://metacpan.org/pod/Perl::Tidy) and use
`perltidy` before submitting patches.
If there is a `tidyall.ini` file, you can also install
[Code::TidyAll](https://metacpan.org/pod/Code::TidyAll) and run `tidyall` on a
file or `tidyall -a` to tidy all files.
### Patching documentation
Much of the documentation POD is generated at release time. Some is generated
boilerplate; other documentation is built from
[Pod::Weaver](https://metacpan.org/pod/Pod::Weaver) pseudo-POD directives in
the source like '=attr', '=method' or '=export'.
If you would like to submit a documentation edit, please limit yourself to the
documentation you see.
If you see typos or documentation issues in the generated docs, please email
the maintainers or open a bug ticket instead of patching.
### Where to send patches and pull requests
If you found this distribution on GitHub, sending a pull-request is the best way to contribute.
If a pull-request isn't possible, a bug ticket with a patch file is the next best option.
As a last resort, an email to the maintainer is acceptable.
## Installing and using Dist::Zilla
Dist::Zilla is not required for contributing, but if you'd like to learn more,
this section will get you up to speed.
Dist::Zilla is a very powerful authoring tool, optimised for maintaining a
large number of distributions with a high degree of automation, but it has a
large dependency chain, a bit of a learning curve and requires a number of
author-specific plugins.
To install it from CPAN, I recommend one of the following approaches for the
quickest installation:
# using CPAN.pm, but bypassing non-functional pod tests
$ cpan TAP::Harness::Restricted
$ PERL_MM_USE_DEFAULT=1 HARNESS_CLASS=TAP::Harness::Restricted cpan Dist::Zilla
# using cpanm, bypassing *all* tests
$ cpanm -n Dist::Zilla
In either case, it's probably going to take several minutes. Go for a walk,
go get a cup of your favourite beverage, take a bathroom break, or whatever.
When you get back, Dist::Zilla should be ready for you.
Then you need to install any plugins specific to this distribution:
$ cpan `dzil authordeps`
$ dzil authordeps | cpanm
Once installed, here are some dzil commands you might try:
$ dzil build
$ dzil test
You can learn more about Dist::Zilla at .
## AI Contributions
Contributions must not include content generated by large language models
(LLMs) or other probabilistic tools, including but not limited to Anthropic,
Copilot or ChatGPT. This policy covers code, documentation, pull requests,
issues, comments, and any other contributions to this project.
This restriction is based on several concerns:
### Maintainer burden
These tools make it easy to generate large amounts of plausible-looking bug
reports or code that the contributor does not understand and cannot explain.
Instead, the burden of understanding is placed on the maintainers.
### Correctness and security
These tools generate code based on probabilities of symbols in their models.
There is no semantic model about what the code does. There is no guarantee
that it is correct, and no indication of what security implications it may
have.
### Copyright issues
These tools may use models that are trained on copyrighted content, both
accidentally and intentionally, and their output often includes that content
verbatim, without attribution. Since the legality of this is uncertain, these
contributions may violate the licenses of copyrighted works.
Using these tools also requires training their models on the source code from
this project, and it makes it likely that code from this project will be used
in other projects in ways that violate this project's license.
### Ethical issues
These tools require an unreasonable amount of energy and water to build and
operate, and they are being used to undermine labour and justify layoffs.
These are harms that the maintainers of this project do not want to
perpetuate, even if only indirectly.

=head1 NAME
Net::CIDR::Set - Manipulate sets of IP addresses
=head1 VERSION
version 0.20
=head1 SYNOPSIS
use Net::CIDR::Set;
my $priv = Net::CIDR::Set->new( '10.0.0.0/8', '172.16.0.0/12',
'192.168.0.0/16' );
for my $ip ( @addr ) {
if ( $priv->contains( $ip ) ) {
print "$ip is private\n";
}
}
=head1 DESCRIPTION
C represents sets of IP addresses and allows standard
set operations (union, intersection, membership test etc) to be
performed on them.
In spite of the name it can work with sets consisting of arbitrary
ranges of IP addresses - not just CIDR blocks.
Both IPv4 and IPv6 addresses are handled - but they may not be mixed in
the same set. You may explicitly set the personality of a set:
my $ip4set = Net::CIDR::Set->new({ type => 'ipv4 }, '10.0.0.0/8');
Normally this isn't necessary - the set will guess its personality from
the first data that is added to it.
=head1 ATTRIBUTES
=head2 type
Either C, C or the name of a coder class.
See L and L for examples of
coder classes.
=head1 METHODS
=head2 new
Create a new Net::CIDR::Set. All arguments are optional. May be passed a
list of list of IP addresses or ranges which, if present, will be
passed to L.
The first argument may be a hash reference which will be inspected for
named options. Currently the only option that may be passed is L.
=head2 invert
Invert (negate, complement) a set in-place.
my $set = Net::CIDR::Set->new;
$set->invert;
=head2 copy
Make a deep copy of a set.
my $set2 = $set->copy;
=head2 add
Add a number of addresses or ranges to a set.
$set->add(
'10.0.0.0/8',
'192.168.0.32-192.168.0.63',
'127.0.0.1'
);
It is legal to add ranges that overlap with each other and/or with the
ranges already in the set. Overlapping ranges are merged.
=head2 remove
Remove a number of addresses or ranges from a set.
$set->remove(
'8.8.0.0/16',
'158.152.1.58'
);
There is no requirement that the addresses being removed be members
of the set.
=head2 merge
Merge the contents of other sets into this set.
$set = Net::CIDR::Set->new;
$set->merge($s1, $s2);
=head2 contains
A synonym for C.
=head2 contains_all
Return true if the set contains all of the supplied addresses.
Given this set:
my $set = Net::CIDR::Set->new('244.188.12.0/12');
this condition is true:
if ( $set->contains_all('244.188.12.128/32') ) {
# ...
}
while this condition is false:
if ( $set->contains_all('244.188.12.0/8') ) {
# ...
}
=head2 contains_any
Return true if there is any overlap between the supplied
addresses/ranges and the contents of the set.
=head2 complement
Return a new set that is the complement of this set.
my $inv = $set->complement;
=head2 union
Return a new set that is the union of a number of sets. This is
equivalent to a logical OR between sets.
my $everything = $east->union($west);
=head2 intersection
Return a new set that is the intersection of a number of sets. This is
equivalent to a logical AND between sets.
my $overlap = $north->intersection($south);
=head2 xor
Return a new set that is the exclusive-or of existing sets.
my $xset = $this->xor($that);
The resulting set will contain all addresses that are members of one set
but not the other.
=head2 diff
Return a new set containing all the addresses that are present in this
set but not another.
my $diff = $this->diff($that);
=head2 is_empty
Return a true value if the set is empty.
if ( $set->is_empty ) {
print "Nothing there!\n";
}
=head2 superset
Return true if this set is a superset of the supplied set.
=head2 subset
Return true if this set is a subset of the supplied set.
=head2 equals
Return true if this set is identical to another set.
if ( $set->equals($foo) ) {
print "We have the same addresses.\n";
}
=head2 iterate_addresses
Return an iterator (a closure) that will return each of the addresses in
the set in ascending order. This code
my $set = Net::CIDR::Set->new('192.168.37.0/24');
my $iter = $set->iterate_addresses;
while ( my $ip = $iter->() ) {
print "Got $ip\n";
}
outputs 256 distinct addresses from 192.168.37.0 to 192.168.27.255.
=head2 iterate_cidr
Return an iterator (a closure) that will return each of the CIDR blocks
in the set in ascending order. This code
my $set = Net::CIDR::Set->new('192.168.37.9-192.168.37.134');
my $iter = $set->iterate_cidr;
while ( my $cidr = $iter->() ) {
print "Got $cidr\n";
}
outputs
Got 192.168.37.9
Got 192.168.37.10/31
Got 192.168.37.12/30
Got 192.168.37.16/28
Got 192.168.37.32/27
Got 192.168.37.64/26
Got 192.168.37.128/30
Got 192.168.37.132/31
Got 192.168.37.134
This is the most compact CIDR representation of the set because its
limits don't fall on convenient CIDR boundaries.
=head2 iterate_ranges
Return an iterator (a closure) that will return each of the ranges
in the set in ascending order. This code
my $set = Net::CIDR::Set->new(
'192.168.37.9-192.168.37.134',
'127.0.0.1',
'10.0.0.0/8'
);
my $iter = $set->iterate_ranges;
while ( my $range = $iter->() ) {
print "Got $range\n";
}
outputs
Got 10.0.0.0/8
Got 127.0.0.1
Got 192.168.37.9-192.168.37.134
=head2 as_array
Convenience method that gathers all of the output from one of the
iterators above into an array.
my @ranges = $set->as_array( $set->iterate_ranges );
Normally you will use one of C, C or
C instead.
=head2 as_address_array
Return an array containing all of the distinct addresses in a set. Note
that this may very easily create a very large array. At the time of
writing it is, for example, unlikely that you have enough memory for an
array containing all of the possible IPv6 addresses...
=head2 as_cidr_array
Return an array containing all of the distinct CIDR blocks in a set.
=head2 as_range_array
Return an array containing all of the ranges in a set.
=head2 as_string
Return a compact string representation of a set.
=for Pod::Coverage compliment
=head1 Retrieving Set Contents
The following methods allow the contents of a set to be retrieved in
various representations. Each of the following methods accepts an
optional numeric argument that controls the formatting of the returned
addresses. It may take one of the following values:
=over
=item C<0>
Format each range of addresses as compactly as possible. If the range
contains only a single address format it as such. If it can be
represented as a single CIDR block use CIDR representation (/)
otherwise format it as an arbitrary range (-).
=item C<1>
Always format as either a CIDR block or an arbitrary range even if the
range is just a single address.
=item C<2>
Always use arbitrary range format (-) even if the range is a
single address or a legal CIDR block.
=back
Here's an example of the different formatting options:
my $set = Net::CIDR::Set->new( '127.0.0.1', '192.168.37.0/24',
'10.0.0.11-10.0.0.17' );
for my $fmt ( 0 .. 2 ) {
print "Using format $fmt:\n";
print " $_\n" for $set->as_range_array( $fmt );
}
And here's the output from that code:
Using format 0:
10.0.0.11-10.0.0.17
127.0.0.1
192.168.37.0/24
Using format 1:
10.0.0.11-10.0.0.17
127.0.0.1/32
192.168.37.0/24
Using format 2:
10.0.0.11-10.0.0.17
127.0.0.1-127.0.0.1
192.168.37.0-192.168.37.255
Note that this option never affects the addresses that are returned;
only how they are formatted.
For most purposes the formatting argument can be omitted; it's default
value is C<0> which provides the most general formatting.
