Which address is a link-local all-nodes IPv6 multicast address?

  • A ff02:0:0:0:0:0:0:1
  • B 2004:33c:94d9:431e:255::
  • C fffe:034:0dd:45d6:789e::
  • D fe80:4433:034:0dd::2
Explanation

The IPv6 link-local all-nodes multicast address is ff02::1. In expanded notation, that is ff02:0:0:0:0:0:0:1. The ff00::/8 prefix identifies multicast, 02 is the link-local scope, and ::1 is the reserved all-nodes group ID for every IPv6 node on the local link.
