The Internet Group Management Protocol (IGMP) is used to define "group" IP
addresses.  The group IP address is then used as a destination address on
a single packet, and causes the packet to be received by all of the hosts
in the group.

See RFC-1054: "Host Extensions for IP Multicasting", by Steve Deering.
