Perl extension for manipulating IPv4/IPv6 addresses
 This package contains the Net::IP module, which provides functions
 to deal with IPv4/IPv6 addresses. The module can be used as a class,
 allowing the user to instantiate IP objects, which can be single IP
 addresses, prefixes, or ranges of addresses. There is also a procedural
 way of accessing most of the functions. Most subroutines can take either
 IPv4 or IPv6 addresses transparently.
