My server has 2 ips: x.x.x.73 and x.x.x.248. I can access my site via these ips, using Web browser.

{Now, from a CentOS machine (not my server), using terminal}
If I:

dig @x.x.x.73 mydomain.com 
dig @x.x.x.248 mydomain.com

I get the result:

Connection timed out; no server could be reached.

Could somebody please tell me how to fix it? Thank you.


More information:

If I log in to my server using ssh and do:

dig @x.x.x.73 mydomain.com
dig @x.x.x.248 mydomain.com

I can see my zone shown as expected:

; <<>> DiG 9.3.6-P1-RedHat-9.3.6-16.P1.el5_7.1 <<>> @x.x.x.73 mydomain.com

  • BIND version 9.3.6, Centos 5.

  • Logging to my server using ssh, do inga "dig google.com" also shows expected results.
