This may be one consequence of trying to make the draft more generic.

The original problem was about DNS (DNS64) as I recall from draft-wing-dhc-dns-reconfigure-02.

There were only two significant transitions in the dns-reconfigure draft: IPv6-only transition to Dual-Stack and Dual-Stack to IPv6-only.

As this option is only for DHCPv6, this is only useful when IPv6 (DHCPv6) is present. The question is whether IPv4 is also present on the host or not as that could influence the DNS information returned.


This one may be a good document to add to the Agenda for the London IETF - to try to resolve exactly what problems this is trying to solve and when, and then to figure out the solution. Hopefully one or more of the authors' will make a request for time at the London IETF.

If the client is IPv4-only, the DHCPv4 server might change its behavior, but the DHCPv6 server would not, because there would be no behavior.   :)
