Which is: not much, if any, atleast without something like DNSSEC to verify something. If we'd be talking about a CNAME that would something else, when we were talking about "out of zone" records. But the parent-zone ? If we can't trust the parent-zone a little, we can't trust the child, because the parent-zone pointed us to it. > It's like verifying gossip :) > > Paul > Not that I want to argue with a DNS-expert, but I'm just surprised at the answer. Ooh, darn I think I know now, it's because it's a different domain, isn't it ? titan.net or it's parents, other then the root are in no way related to nmap.org. I wonder if Bert considers it a bug in 3.1.7 ?
