Assuming that you do that, what would you be your criteria to find based
on RR if the ip is anycasted or not?
I mean lets suppose that I run dns server at AS0 and peer at location A
and also at location B with same ISP with AS1. I might have one dns server
at location A and another different one at location B, which means its
anycasting. But from peering perspective it would just appear as the
same path AS0->AS1 no matter what location it is.
Opposite to that route to the same server might be seen from different
peer AS# based on location because of routing policies.
