From a practical standpoint, yes, we can, in a way. When we build our .Web zone, we do an SOA check on the name servers given. If the check fails such that there aren't 2 valid name servers that both resolve and answer with authority, the name doesn't go in the zone. The problem becomes apparent rather quickly, and the customer is notified that they need to fix it. But this is a policy at our registry, as it should be. Christopher
