Tim, thank you for the reference, we are using something close-to-but-not
RFC6296.

The reason we are not saying "RFC 6296" is that in the design that is being
implemented, we do not want to claim compliance at all with a standard, but
ask the client if he understands and approves of the design.

We had an issue in an earlier implementation when the Windows server team
was worried that nodes with two IPv6 addresses might pollute and confuce
dynamic updates in the AD DNS.  No one wanted to test this, rather than
delay the IPv6 rollout, we dropped global IPs in the internal network.

I am a vice-chair of the IPv6 Forum Singapore Chapter, and my focus is to
roll out more and more IPv6.  Numbers, Sir, not Quality!
