Internet Group Management Protocol
IGMP is an Internet protocol that enables an Internet computer
to inform neighboring routers that it is a member of a multicast
group. With multicasting, a computer can send content on the
Internet to several other computers that have registered an
interest in the content of the first computer. Multicasting can, for
example, be used for multimedia programs for media
streaming to recipients that have set up multicast group
membership.
