3.2.3 Internet Group Management Protocol IGMP
IGMP [IP:4] is a protocol used between hosts and gateways on a
single network to establish hosts' membership in particular
multicast groups. The gateways use this information, in
conjunction with a multicast routing protocol, to support IP
multicasting across the Internet.
At this time, implementation of IGMP is OPTIONAL; see Section
3.3.7 for more information. Without IGMP, a host can still
participate in multicasting local to its connected networks.
