I agree.

As a side note: could it be possible to DoS name servers by querying 
tons of non-existant .net domains? As example, if several users of a DSL 
provider try to query random and thus most probably non-existing .net 
domains that now all deliver the afore mentioned IP as result, could it 
be possible to bring the DNS servers down? I guess not, because those 
servers should be able to throw away old queries in case a configured 
memory limit is reached. On the other hand this could cause additional 
traffic and slower responses for other customers as valid DNS entries 
have to be re-queried from the DNS-uplinks. Am I right with this?

Bye, Mike
