The SQL type inet describes IPv4 network addresses. The inet module contains a collection of functions that operate on IPv4 addresses. The most relevant functions are the `containment' functions that deal with subnet masks.

The functionality of this module is greatly inspired by the PostgreSQL inet atom. It should be extended to also support IPv6.
