External (not in the same domain) name server

presuming you mean that there should be registered host rr
for all known servers. otherwise, i suspect the servfails
will get even worse.

sadly, forcing an A RR does not ensure that the server is
in fact serving the zone. i would not be unhappy if the
registrar or registry would test this occasionally.


  ah... the good ol days. when this was checked. :slight_smile:
