(But you'd be giving up the autoconfiguration > advantages.) I noticed that by deafult MS Vista doesn't use autoconf as per 2462, rather it uses a 3041-like random address. See: http://www.microsoft.com/technet/itsolutions/network/evaluate/new_network.mspx "Random Interface IDs for IPv6 Addresses To prevent address scans of IPv6 addresses based on the known company IDs of network adapter manufacturers, Windows Server "Longhorn" and Windows Vista by default generate random interface IDs for non-temporary autoconfigured IPv6 addresses, including public and link-local addresses." That reads to me like no 2462 by default. Maybe I'm misinterpreting. One could envisage an option where that randomness is applied to 48 host bits not 64. If you really really wanted to do that. -- Tim/::1 _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
