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

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.

So, in short, UMD will still own the losing allocation, and be able to make 
relatively sure nothing else is placed at that IP (though of course they 
won't necessarily be able to make sure no one hijacks that entire prefix --
does Renesys have a pay-special-attention list?)

        But how do you know the Renesys allocations haven't been hijacked??
