DNS roots c, f, i, j, k, and m all do something like that, and last I
checked those were all the anycasted DNS roots. But more may have become
so since I last checked. It's true that they don't have to do it, but
it's a common enough convention for all the root DNS operators seem to
have agreed on it, and I've been told that DNS root ops is a highly
contentious subject, so any agreement at all is kind of a nice thing to
note.
Or am I misunderstanding what you are saying?
This is, of course, somewhat off the subject of whether the original
provider in question does that - they may or may not, and the only way to
know is to test and find out. Or ask them.
