The Internet Group Management Protocol (IGMP) manages the membership of hosts

and routing devices in multicast groups. IP hosts use IGMP to report their multicast group

memberships to any immediately neighboring multicast routing devices. Multicast routing

devices use IGMP to learn, for each of their attached physical networks, which groups

have members.
