The old address, which is in the middle of UMD's network, is going to be black-holed once the change is over. Nothing will be on that IP once we move the root off. The rest of UMD's network is staying put. This move is part of UMD's commitment to improve the service, so we can support DNS anycast.
Just a quick question....if the old block is going to be black-holed but kept allocated...why does it need to be changed in the first place, or why does the existing have to be disabled? (just have both addresses active/responding?)
Forgive me if I'm missing something.
because you would not accept a /30 cutout of the UMD /16 coming from some random IX in Singapore. (see Joe Ableys post earlier today on why legacy nodes are / have renumbered.) /bill
