DNS anomaly

Thanks for that correction.

The problem fixed itself when the NS record for ninthave.net expired 
from the offending DNS server. When these records were reloaded, the 
corresponding A records for my nameservers were found.... can't 
understand why they weren't found previously, but it appears to be 
specific to the .net domain.

I get the impression that when the DNS server first loaded ninthave.net 
it couldn't find an A record for the nameservers (perhaps a network 
outage, or wasn't supplied with one from the .net nameservers), and it 
never tried again to find these records.

...OR... it *was* trying to find these records but was querying 
ns.ninthave.net (for the address a.ns.ninthave.net)..

... nope, that doesn't make sense either... still confused ...

Thanks for your help

Roger
