Given the IPv6 address of 2001:0DB8::1:800:200E:88AA, what will be its corresponding the
solicited-node multicast address?
A.
FF01::1:200E:88AA
B.
FF01::1:FF0E:88AA
C.
FF01:0DB8::1:800:200E:88AA
D.
FF02::1:FF0E:88AA
E.
FF02::1:200E:88AA
F.
FF02:0DB8::1:800:200E:88AA
The solicited-node multicast address is a multicast group that corresponds to an IPv6 unicast or anycast address. IPv6 nodes must join the associated solicited-node multicast group for every unicast and anycast address to which it is assigned. The IPv6 solicited-node multicast address has the prefix FF02:0:0:0:0:1:FF00:0000/104 concatenated with the 24 low-order bits of a corresponding IPv6 unicast or anycast address.
For example, the solicited-node multicast address corresponding to the IPv6 address 2037::01:800:200E:8C6C is FF02::1:FF0E:8C6C. Solicited-node addresses are used in neighbor solicitation messages.

Solicited-node multicast addresses are used in neighbor discovery protocol (NDP) for obtaining the Layer 2 link-layer addresses of other nodes. Solicited-node multicast addresses are used with IPv6 NDP to provide the same function as Address Resolution Protocol (ARP) in IPv4.
