Hello;

I've a Centos VPS as web server and I've some domains on it as Virtual Hosts.

Let me explain my problem: example.com dnsses (dns1.example.com to dns8.example.com) does not resolving some of my domains ip, but it resolves others on the same server with same configurations.

There are no differences at named.conf file for domains. Also all domains on same server with same IP. It's just a little web server.

All other DNS servers are resolving my addresses except some national ISPs of my country.

I made a comparison PDF file <snip>

I've no idea what to do, I've no idea what can be the reason of problem.

Can somebody guide me what steps I must take? I just need help...

Thanks for reading, waiting for your replies.
