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.
MLD protocol version2 use FF02::16 as destination address of membership report, and 143 as data type. The
other logic of MLD Protocol version2 is similar to IGMP Protocol version3.
