Ok, thanks .. useful information. And, the client/server seem to be able to interoperate so that is good.

Hi Bernie,

IPv6 Ready DHCPv6 Logo has never had a test for this, so I have no idea what the support is for general DHCPv6 Clients/Servers.

At QACafe we see about 50% of the Home Gateways support it as we have a test for verifying it.

That’s my guess as well.

Perhaps Tim W has some data as to whether it is used or not (and whether it is even tested).

If it isn’t used / implemented, may also be difficult to confirm interop.

Anyway, perhaps something to consider as part of the “full” Standard work to see if we need a post-8415.

I really wonder how large an issue this is and how frequently Server Unicast is even used. Perhaps in retrospect, a feature we might have considered removing.

I’d be surprised if it’s used—it’s a knob you’d have to configure that doesn’t make things work better. IIRC we put it in because not everybody agreed that just requiring multicast always was a good move.
