Well, we should expect more: * All NS records in the zone must point at authoritative servers. * If glue is needed in the delegation, that record must be present in the zone. And all addresses of that glue must point at authoritative servers. * The SOA record must have a working email address. * All non-glue NS records must point at names having an A record in its authoritative zone. * All servers must have identical SOA and NS RR set.
