I am running a dedicated server.
The server is running two sites. This morning one website is not working and I found that there is a problem with the dns settings. I don't know how it happened very suddenly.
The other website is working properly.
nslookup @domainname.com Server: 220.127.116.11 Address: 18.104.22.168#53 ** server can't find @domainname.com: NXDOMAIN
I checked online dns tools and they are reporting errors.
nslookup for another site is also not working
But dig for another site is working properly.
dig @domainname.com dig: couldn't get address for 'domainname.com': not found
and ping is reporting
ping: unknown host domainname.com dig SOA sitename.com ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6_4.6 <<>> SOA sitename.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 25377 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;sitename.com.

I tried one online website for nslookup.
