Please, let's not OD on DHCP in this thread: while I was making a point about DHCP, I was really making a more general point about robustness in homenet, and how to judge various proposals, more than specifically attacking recursive DHCP-PD as a concept. Similarly, I think as another goal we have

I'm not against one or more /64 bit prefixes for a home net, if everyone else (including the ISPs) think that home networks should be able to scale up to 18,446,744,073,709,551,615 hosts, I'm completely on board. It's not my resource, so I'll take all they give me. :) It would be nice to
