This is another module to manipulate IPv4/IPv6 addresses. In contrast
of NET::IP, it does not require Math::BigInt. Also, it supports some
additional IPv4 formats like 0x7f000001, 2130706433, 017700000001,
0177.0.0.1, 0x7f.0.0.0x1.

The module provides the following capabilities:

* validating IP addresses;
* converting IP addresses in different format;
* comparing IP addresses;
* verifying whether an IP is an IPv4 or an IPv6 or
an IPv4-embedded IPv6 address;
* verifying whether an IP is in a range.
