IP is, as mentioned above, a collection of tools to work with IP addresses. There are three major classes included in the IP namespace, IP::Address, which works with standard dotted-quad IP addresses, IP::Range, which can calculate and return a range of IP::Address objects, and IP::CIDR, which can work with Classless Inter-Domain Routing address formats.

The IP module uses long integers and bit-flipping per <netinet/in.h> to achieve fairly efficient performance, as opposed to a purely iterative approach. This is most true when calculating ranges and netmasks.

Please see the documentation for each of these classes for usage information.

Note: there is no IPv6 support as of current, but this is planned in perhaps a distant, future release. Any patches that can correct this issue are most welcome.

Also: Thanks to Tim Howe, who did a lot of initial bug testing and ‘trial by fire’ as this package came out of it’s shell. Writing new methods that made code easier to understand and/or clearer, and making plenty of suggestions made creating this module much easier.
