[ERROR: The parent servers say that the domain qdata.net.au does not have any NS records (although they may have some other information on that zone). I can not do a DNS report on a hostname (such as mail.example.com) or a domain name that does not have its own zone.]
I have no clue why it's not working(already after 72 hours), the other domains work just fine.
Truthfully I don't know how the .au gtld delagates ns lookups.
No NS records exist for qdata.net.au. [Neg TTL=86400 seconds]
ns1.dnsserver3.com. (an authoritative nameserver for qdata.net.au.) says that there are no NS records for qdata.net.au.
The E-mail address in charge of the qdata.net.au. zone is: [email protected].
This message here states that ns1.dnsserver3.com is authoritative, then searches there for the nameservers of qdata.net.au. Do you have the same set up for the other net.au that you host ?
