Doing 1 to 1 match between a hardware address and an IPv6 address, and add meaning into the IPv6 address instead of treating it for what it is, just an address that should be generated somehow other than directly from a hardware address. That it also has a privacy side issue with it don't make it any better. Plenty of suggestion on how that can be used have been mention. -- Roger Jorgensen | ROJO9-RIPE rog...@gmail.com | - IPv6 is The Key! http://www.jorgensen.no | ro...@jorgensen.no -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
