Perl extension for access to network card configuration information
IO::Interface adds methods to IO::Socket objects that allows them to be used to retrieve and change information about the network interfaces on your system. In addition to the object-oriented access methods, you can use a function-oriented style. IO::Interface::Simple allows you to interrogate and change network interfaces. It has overlapping functionality with Net::Interface, but might compile and run on more platforms.
