Solicited-Node Address: FF02:0:0:0:0:1:FFXX:XXXX Solicited-Node multicast address are computed as a function of a node's unicast and anycast addresses. multicast A Solicited-Node address is formed by taking the low-order 24 bits of an address (unicast or anycast) and appending those bits to the prefix FF02:0:0:0:0:1:FF00::/104 resulting in a multicast address in the range FF02:0:0:0:0:1:FF00:0000 to FF02:0:0:0:0:1:FFFF:FFFF Hinden [Page 16] Standards Track RFC 4291 February 2006 IPv6 Addressing Architecture For example, the Solicited-Node multicast address corresponding to the IPv6 address 4037::01:800:200E:8C6C is FF02::1:FF0E:8C6C. IPv6 addresses that differ only in the high-order bits (e.g., due to multiple high-order prefixes associated with different aggregations) will map to the same Solicited-Node address, thereby reducing the number of multicast addresses a node must join. A node is required to compute and join (on the appropriate interface) the associated Solicited-Node...
