What is IGMP?

Internet Group Management Protocol (IGMP) is a communications protocol used by hosts and adjacent network routers on IP networks to establish multicast group memberships. IGMP is an integral part of IP multicast, allowing network devices to efficiently forward multicast traffic only to the interested recipients, thus conserving bandwidth and resources. It's commonly used in applications like streaming video, online gaming, and other scenarios involving data distribution to multiple receivers.
