IO::Interface adds object-methods to IO::Socket objects to allow them
to get and set operational characteristics of network interface cards,
such as IP addresses, net masks, and so forth.  It is useful for
identifying runtime characteristics of cards, such as broadcast
addresses, and finding interfaces that satisfy certain criteria, such
as the ability to multicast.
