IGMP General Query message: IGMP querier sends IGMP General Query

which members of the multicast group are in this network segment.
IGMP Report message: members respond with IGMP report messages when
they receive IGMP IGMP General Query messages. Members send IGMP Report
messages to IGMP querier proactively to declare joining this multicast group.
IGMP Leave message: members that run IGMPv2 or IGMPv3 send IGMP leave
report to notify IGMP querier that they have left some multicast groups.
