No, the question is if there is any host stack + server software that deals with flash renumbering deployed.
And that is deployable without coding.

It's the same question Owen posed for the ISP side, when challenged with how DHCP behaves.
The point here is that we as the IETF must also consider the end-user here. Not that I don't think ISPs do that too, but so far this debate has largely been on the premise of the opertor with little concern of the consequences for the user.

Cheers,
