The Internet Group Management Protocol (IGMP) is a communications protocol used by hosts and adjacent routers on IPv4 networks to establish multicast group memberships. IGMP is an integral part of IP multicast and allows the network to direct multicast transmissions only to hosts that have requested them.

The Internet Group Management Protocol (IGMP) is a protocol that allows several devices to share one IP address so they can all receive the same data. IGMP is a network layer protocol used to set up multicasting on networks that use the Internet Protocol version 4 (IPv4).

2024年8月26日 · IGMP is an acronym for Internet Group Management Protocol. IGMP is a communication protocol used by hosts and adjacent routers for multicasting communication with IP networks and uses the resources efficiently to transmit the message/data packets.

IGMP (Internet Group Management Protocol) is a Host-Router Multicast Signalling Protocol that provides dynamically registration of the hosts to the desired Multicast Groups. With IGMP, Host requests to join to the Multicast Groups. This join request comes to the DR (Designated Router).

2025年1月21日 · The Internet Group Management Protocol (IGMP) is a part of the TCP/IP protocol suite used to manage IPv4 multicast group membership. IGMP sets up and maintains membership between receiver hosts and directly connected multicast routers by exchanging IGMP messages between them.

2016年3月17日 · Internet Group Management Protocol (IGMP) is used to dynamically register individual hosts in a multicast group on a particular LAN segment. Enabling Protocol Independent Multicast (PIM) on an interface also enables IGMP operation on that interface.

Introduction The Internet Group Management Protocol (IGMP) is used by IP hosts to report their multicast group memberships to any immediately- neighboring multicast routers. This memo describes only the use of IGMP between hosts and routers to determine group membership.
