Right; it's the link-local address of the router to which you've delegated the prefix. It's not the address of every single machine on the customer's network. In fact, knowing the addresses of the machines on the customer's network is useless, as it doesn't tell you the address of that CPE router. Obvious sorts of ways to get this would be to keep track of your delegations or (alternatively) use an appropriate routing protocol. -- James Carlson, Solaris Networking <[EMAIL PROTECTED]> Sun Microsystems / 1 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
