Net-IPAddress-Util The goal of the Net::IPAddress::Util modules is to make IP addresses easy to deal with, regardless of whether they're IPv4 or IPv6, and regardless of the source (and destination) of the data being manipulated. The module Net::IPAddress::Util is for working with individual addresses, Net::IPAddress::Util::Range is for working with individual ranges of addresses, and Net::IPAddress::Util::Collection is for working with collections of addresses and/or ranges. INSTALLATION To install this module, run the following commands: perl Makefile.PL make make test make install If you would like to run the (time-consuming) battery of time trials, for instance to decide whether or not it's worthwhile prefering Radix Sorting over Perl's built-in sort, please set the environment variable IP_UTIL_TIME_TRIALS to a true value before running 'make test'. If you do run the time trials, I'd appreciate it if you could email the diag messages (including the line listing the backend library in use) to me at paul.w.bennett@gmail.com SUPPORT AND DOCUMENTATION After installing, you can find documentation for this module with the perldoc command. perldoc Net::IPAddress::Util You can also look for information at: RT, CPAN's request tracker http://rt.cpan.org/NoAuth/Bugs.html?Dist=Net-IPAddress-Util AnnoCPAN, Annotated CPAN documentation http://annocpan.org/dist/Net-IPAddress-Util CPAN Ratings http://cpanratings.perl.org/d/Net-IPAddress-Util Search CPAN http://search.cpan.org/dist/Net-IPAddress-Util/ COPYRIGHT AND LICENCE Copyright (C) 2010 Paul Bennett This program is free software; you can redistribute it and/or modify it under the terms of either: the GNU General Public License as published by the Free Software Foundation; or the Artistic License.
