specific group in its subnetworks according to the response message received, and after
it receives the report of a host quitting from the group, it sends out the query for the group
to confirm if there is no member left in it.
There are three types of protocol messages of MLD Protocol, that is, Query, Report
and Done (which is corresponding to Leave of IGMPv2). Like IGMPV2, the Query
messages include General Query and Specific Group Query. General Query uses the
multicast address FF02::1 of hosts as destination address, the group address is 0; and
Specific Group Query use its group address as destination address. The multicast
addresses of MLD use 130, 131 and 132 as data types denoting the three kinds of
messages mentioned above. Other logic is basically same as IGMPv2.
