Quizplus · Accepted Answer

IGMP (Internet Group Management Protocol) is the IPv4 protocol that handles multicasting for tasks such as videoconferencing or teleconferencing. It is used by devices on a network to report their multicast group memberships to neighboring multicast devices, allowing routers to direct multicast traffic to only those devices that have expressed interest in receiving it. ICMP, ARP, and TCP are not designed for multicast management.
