Notes / Warnings

RFC #4291 Section 2.7.1 specifies that "Solicited-Node multicast address are computed as a function of a node's unicast and anycast addresses. A Solicited-Node multicast 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" from :
FF02:0000:0000:0000:0000:0001:FF00:0000
to ...
FF02:0000:0000:0000:0000:0001:FFFF:FFFF"
