Explanation

IGMPv2 defines three message types: Membership Query (Type 0x11), Membership Report (Type 0x16), and Leave Group (Type 0x17). A Membership Report is sent by a host to announce that it wants to join (or remain in) a multicast group. It is sent to the multicast group address being joined. In a packet capture, the IGMPv2 Membership Report is identifiable by its type code 0x16 and a destination address matching the group being reported. The exhibit for this question displays the characteristics of a Membership Report rather than a query or leave message.
