Weird. I have the zone entry for anonns.com binding to advanced.anonns.com as follows:-
;Begin of file anonns.com $TTL 86400 @ IN SOA advanced.anonns.com. postmaster.anonns.com. ( 2005040301 3600 7200 864000 86400 )
IN NS advanced.anonns.com. IN NS brilliance.anonns.com.
IN MX 5 advanced.anonns.com.
IN A 203.208.228.152 ftp IN A 203.208.228.152 mail IN A 203.208.228.152 pop IN A 203.208.228.152 www IN CNAME anonns.com. advanced IN A 203.208.228.152 brilliance IN A 203.208.228.153
I am getting petty confused.
It's difficult to diagnose the problems from here (both my work and home machines, on completely separate networks) because I'm getting a lot of DNS query timeouts from your servers (brilliance.anonns.com seems to be more reliable at the moment). It may be that it's a network connectivity issue that's underlying your problems. Is it possible for you to get an additional DNS server on a separate network to act as an additional secondary for your domains? Both of your current DNS servers are currently on the same network, which doesn't help reliability.
The file above looks OK, though I'd be tempted to add a line: $ORIGIN anonns.com. at the top.
