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
