It is true that ILNP uses multicast addresses; so do a number of applications, such as multicast DNS, routing protocols, etc. Last I checked, an IPv6 multicast address is not identified by having bit 71 of the address set to 1 (RFC 4291 section 2.5.1), but by being within the prefix FF00::/8 (RFC 4291 section 2.7). -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
