I have set up a DNS server using BIND on CentOS 7. By checking the DNS server in BuddyNS and using
dig amraei.com it seems good and working.
Then I have also setup Apache and a virtual host for another domain
involv.ir. Now the domain
involv.ir is not accessible and replying to
ping. If I try to trace it, I get this error:
:~$ mtr involv.ir Failed to resolve host: Temporary failure in name resolution
While tracing DNS server using
mtr amraei.com shows it's working properly.
How to troubleshoot this problem and check if it is DNS or Apache related?
