Which of the following answers lists a multicast IPv6 address?
A.
2000::1:1234:5678:9ABC
B.
FD80::1:1234:5678:9ABC
C.
FE80::1:1234:5678:9ABC
D.
FF80::1:1234:5678:9ABC
Explanation:
Global unicast addresses begin with 2000::/3, meaning the first three bits match the value in
hex 2000. Similarly, unique local addresses match FD00::/8, and link local addresses match
FE80::/10 (values that begin with FE8, FE9, FEA, and FEB hex).Multicast
IPv6 addresses begin FF00::/8, meaning the first two hex digits are F.
