Dns issue - Host domain.tld not found: 2(SERVFAIL)

[My level of knowledge with vps , linux and bind dns settings are at learning/begginer stage]

  1. Added domain/PTR to droplet with ip

  2. Then somehow setup a vanity nameserver named ns1/ns2/ pointing to ns1/ns2/ Hope it is working fine.

  3. Afterwards added a user account called through CWP. But domain was not reaching the droplet. So issued #Host and received “Host not found: 2(SERVFAIL)” error.

Can anyone please help me to fix the issue?

Accepted Answer

The issue is solved. It was due to missing A records for NS1/NS2/NS3 vanity nameservers in the droplet’s DNS manager.

Sharing some of the data:

a) #cat /etc/named.conf (some lines are removed)

zone “” in { type master; file “/var/named/245.58.51.rev.db”; }; zone “” { type master; file “/var/named/”;};
