Quite so: UMD: Where will the old IP route after the 6 month period is 
complete?  Somewhere safe?

In point of fact, ISTM that there *is no way* to make this completely safe;
granted that it's a low percentage attack, and thus probably not useful
to actual attackers, but the possibility exists that someone could hijack 
that block at a provider level, and provide their own replacement for that
old server IP.

But of course, they can do it *now*, too, so I guess it doesn't matter
