    Hi All,

    I am about to depoly 3 servers, 1 full cPanel/WHM server + 2x DNSOnly servers. The way I want to deploy the servers are like follows:

    NS1 & NS2 will be the DNSOnly servers. They'll be read-only servers.
    All DNS updates will be pushed from the Full cPanel server.
    NS1 and NS2 needs to offer recursive lookups for selected IP ranges.

    If you can provide my with details on how to achieve this, that would be great.

    I am aware on how to setup the clustering options on cPanel but a bit lost on how to get the DNS requirements done.

    Appreciate any and all feedback with regards to this matter :)

    Kind Regards,

    Hello Asanka,

    I recommend using the Direct Links setup that we document on the link below:

    Guide to DNS Cluster Configurations - cPanel Knowledge Base - cPanel Documentation

    When accessing WHM >> DNS Cluster on the each DNSOnly server, choose Standalone as the DNS role:

    When accessing WHM >> DNS Cluster on the full cPanel & WHM server, choose Write-only as the DNS role:

    You can configure the /etc/named.conf files on each DNSOnly server to allow recursive lookups for selected IP ranges. There's no feature in the UI to do this, but the custom changes you make to the /etc/named.conf files are not overwritten.

    Thank you.
