Well, actually, this discussion may need to be nuanced. The requirement should be that that if there is a PTR record (i.e., with a delegation chain starting at in-addr.arpa), the authoritative servers that would be traversed in chasing down the record must all be globally reachable. That probably means non-ULA addresses, though there might be some edge cases. > I think Mark was assuming that ULA address for authoritative > delegation point might be OK, which would lead to issues if the ULA > address is not reachable from everywhere where reverse DNS lookups > should succeed. Not acceptable to have glue records that contain addresses that are not generally reachable. The DNS is not designed to operate efficiently in such an environment.
