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.
Interest in multicast traffic from a specific source is conveyed from hosts to routers using IGMPv3 as specified in RFC 4607. SSM destination addresses must be in the ranges 232.0.0.0/8 for IPv4 . For IPv6 current allowed SSM destination addresses are specified by ff3x::/96 , where the hexadecimal digit x represents the scope. [ 1 ]
The Internet Group Management Protocol with Access Control (IGMP-AC) has been designed for incorporating AAA protocol functionality in the existing IP multicast model. It will enforce authentication and authorization of an end user or receiver before joining or leaving a secured multicast group.
IGMPv2 and IGMPv3 contain provision for selecting a querier when multiple are available. The querier with the lowest IP address is given the role. [2] [3] IGMP general queries from the querier must be unconditionally forwarded by all switches involved in IGMP snooping. [1]
IP multicast is a method of sending Internet Protocol (IP) datagrams to a group of interested receivers in a single transmission. It is the IP-specific form of multicast and is used for streaming media and other network applications.

IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).
A multicast address is a logical identifier for a group of hosts in a computer network that are available to process datagrams or frames intended to be multicast for a designated network service.
