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.
This is an extremely good point... Where will the former addresses be going after this?
As I understand it (but ask UMD!) - D-Root is currently numbered out of a general-purpose UMD /16 into a dedicated, specifically-assigned /24 - the UMD /16 is not going anywhere The announcement is that D-Root is being renumbered, not that UMD is renumbering its whole network. Other root servers have renumbered out of institutional, general-purpose networks into dedicated networks in the past. I think the last one was B-Root in 2004, from an address within 128.9.0.0/16 to an address within 192.228.79.0/24 (see <http://www.root-servers.org/news/new-ip-b.html>).
I'm sure someone's thought about that though...I hope.
