Which of the followings is an IPv6 multicast address?
A . 2222::11
B. FF02::18C
C. FE80:: A
D. FC00::1

Answer: B

Explanation:

FF02::18C is an IPv6 multicast address. An IPv6 multicast address starts with FF and identifies a group of interfaces that belong to the same multicast group. The other options are not IPv6 multicast addresses. 2222::11 is an IPv6 unicast address, FE80::A is an IPv6 link-local address, and FC00::1 is an IPv6 unique local address.
