There is an RFC that describes how hosts should select addresses in such =
situations,
http://tools.ietf.org/html/rfc3484
As an side; it would be great if some more IPv6 questions could be put =
on http://ipv6exchange.net/ - I would love to see that become a useful =
resource for people starting out with IPv6. If you have an IPv6 =
question, please do post!
