If you have FreeBSD or Windows you can manipulate the "policy table" to make this happen.

It's a bit too complex to explain how this works in a post though, but try:

# ip6addrctl show

or

C:\>netsh
netsh>interface ipv6
netsh interface ipv6>show prefixpolicy

RFC 3484 provides background info. And of course any IPv6 book worth its salt explains it all in great detail. :-)
