Then why are there 64 bits in the IID? And I don't think it has anything to do with the MAC address. 1000 IPv6 addresses on 10 MAC addresses scales as well as 1000 IPv6 addresses on 1000 MAC addresses. It might make a difference for the switch, but not for ND/NC. - Sander PS: I consider having the possibility of having a large amount of IPv6 addresses on one interface a great feature, not something I would want to limit. -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
