Multicast and IGMP
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient)
or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of
hosts on the network - not everybody and not just 1.
IGMP (Internet Group Management Protocol) is a network-layer protocol used to establish
membership in a Multicast group - it is not used to carry user data.
