DNS Not Working on Primary Server, How to connect cPanel DNS only server?

whoisiyush
Hello There, I have a primary cPanel Server with IP- 1.1.1.1 and hostname and nameserver as follows: server.example.com ns1.example.com ns2.example.com Hostnames are pointing at my server i.e 1.1.1.1, but due to some issue with my isp's side, DNS is not working. So I want to use external DNS servers from my primary cPanel Server i.e server.example.com .I read a thread about cPanel DNS Server, so will it work as my primary DNS server? after doing some config? If yes, then please do tell me the way to do it. Help Will Be Appreciated

    Sure - that would work very well. Details on the cluster configuration can be found here:

    If the server isn't able to resolve a domain at all, you'll want to look at the test from my first post to see if it is a local configuration issue. It's possible your network may not support DNS queries.

    nmap gives this output- root@titan ~]# nmap -sU ns1.exampledomain.com -p 53 Starting Nmap 6.40 ( Nmap: the Network Mapper - Free Security Scanner ) at 2022-06-13 17:09 EDT Failed to resolve "ns1.trendship.in".

    Thanks for that - this would indicate that there are two issues happening - port 53 is being filtered on your network and your hostname doesn't have the proper DNS configuration for the nameservers to work. With the port 53 issue, that network is likely not a good option for hosting nameservers.

    should i change my isp? and one more thing can i use external dns server in order to fix this issue? something like any other Cpanel dns only server hosted on Aws or any other provider that provides top notch networking? if yes how? and also in order to use non Cpanel Dns server how can i do that too? Help is really appreciated

    You may be able to use a DNSOnly server and create a DNS cluster to resolve this issue. cPanel servers aren't designed to be used on private networks, as many of the common ports may not be available through your ISP. A datacenter host would have all of the ports open necessary for all tools to function. You could use a non-cPanel DNS server as well, but you'd need to manually enter your DNS information into that server, which is more work and more possible room for error.

    Thanks For Helping me Out ! i just wanted to ask one things- pls check below config i"m setting up ip"s -> server.example.com -> 1.1.1.1 (Home Server) Nameservers (Dns only cPanels) ns1.example.com -> 2.2.2.2 ns2.example.com -> 3.3.3.3 in Basic Web Host Manager Config in Home Server i will add my nameservers and put ipv4 addresses of the dns servers right? ns1-> 2.2.2.2 ns2-> 3.3.3.3 is it okay?

    That all sounds fine, but it's important to note that configuring the nameservers in WHM >> Basic Web Host Manager Configuration only creates the records locally and tells cPanel to use those nameservers in future DNS zones you create. You still need to ensure the nameservers are configured in DNS and at the registrar level.
