module for sending and receiving multicast messages
The IO::Socket::Multicast module subclasses IO::Socket::INET to enable
you to manipulate multicast groups. With this module (and an operating
system that supports multicasting), you will be able to receive incoming
multicast transmissions and generate your own outgoing multicast
packets.
