For the AS112 project I have used the open resolver data to try and
'count' the number of anycast nodes by unique instances. It would
probably be one more step to infer location - But I'd need to rely on
people taking the advice found in RFC6304 to state their location via the
TXT record. The end-goal of the effort is two-fold:
- how many AS112 servers there are
- where are they and how close are they to each other.
The latter would be an educated guess based on the data. But I think this
is what you are after as well.
Wasn't there a draft in DNSOP which would also make anycast nodes more
