Hehe, quite a few:
NS records from your nameservers:
NS records got from your nameservers listed at the parent NS are:
Oups! I could not get any nameservers from your nameservers (the ones listed at the parent server). Please verify that they are not lame nameservers and are configured properly.
Mismatched NS records
WARNING: One or more of your nameservers did not return any of your NS records.
DNS servers responded
ERROR: One or more of your nameservers did not respond:
The ones that did not responded are: 75.###.38.###
ERROR: Looks like you have less than 2 nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me.
Missing nameservers reported by your nameservers:
You should already know that your NS records at your nameservers are missing, so here it is again:
SOA record No valid SOA record came back!
Oh well, I did not detect any MX records so you probably don't have any and if you know you should have then they may be missing at your nameservers!
WWW A Record
ERROR: I could not get any A records for www.mydomain.com!
(I only do a cache request, if you recently added a WWW A record, it might not show up here.)
Is the intended behavior for my name servers (ns1.nameserver.com, etc) to point to the default server webpage? When I type in ns1.nameserver.com it gives me this message:
This is the default web page for this server.
The web server software is running but no content has been added, yet.
