For *NIX-type platforms, there is the IO::Interface module which allows local interfaces to be enumerated via additional methods added to IO::Socket objects. These methods allow interface information to be both retrieved and modified.

For example ...

use IO::Interface; use IO::Socket; my $sock = IO::Socket::INET->new( 'Proto' => 'udp' ); foreach my $iface ( $sock->if_list ) { print $iface, " ", $sock->if_addr, "/", $sock->if_netmask, "\n"; }
