    We used to run 3 X cPanel servers
    1 was a backup server and ran our secondary dns service (ns2)
    1 was a webserver (web)
    1 was a webserver which also ran our primary dns (ns1)

    all worked fine

    we have let the backup server go (underutilised) and thought we had switched over our secondary dns to the other webserver

    we have the nameserver domain running on ns1 and i edited the dns zone to add a new NS and A entry for the webserver to call it

    We have bind running on web server

    I can query ns3 fine on the server itself but everywhere else isn't seeing it and hence lookups don't work

    I am no DNS expert so at a loss as to where to go from here ?

    Should the A entry for the ns3 host be pointing to the shared IP or does it need its own IP ?

    Hello :)

    Ideally, you should have separate servers for DNS purposes only if you are configuring a cluster. You can install cPanel DNS-Only on the servers that you use for DNS purposes only. That being said, while not recommended, you can configure the web servers to synchronize DNS changes to one another. Are you using the DNS clustering feature in Web Host Manager? It's documented at:

    Configure Cluster

    Or, are you simply utilizing Bind on two different web servers and do not plan on having the same DNS Zones on each server?

    Thank you.
