So I'm looking at a company who offers anycasted DNS;
how do I tell if it's really anycasted?  Just hop on
different route servers to see if I can find different
AS paths and then do traceroutes to see if they suggest
the packets are not ending in the same location?
From my routers' perspective I don't see a difference,
but then I don't think I should, correct?

Thanks,

David
