    This has been driving me nuts for years and I believe has caused so many unnecessary problems. Our former it guy setup our name servers and our dedicated servers. We just had our servers moved to a new location and the IT guy mentioned that they are set up wrong.

    Here is the setup

    Server 1:
    • has nameserver domain "serverdns.com"
    • Name Server selection = BIND
    • IPv4 set to IP address #1 (IP#1)
    • Name servers set to
      • ns1.serverdns.com with IP#2 and
      • ns2.serverdns.com with IP#1
    Server 2:
    • Name Server selection = BIND
    • IPv4 set to IP address #1 (IP#2)
    • Name servers set to
      • ns1.serverdns.com with IP#2 and
      • ns2.serverdns.com with IP#3 (assigned to Server1) ** this must be wrong**
    Can someone tell me if there is a better way to do this?
    Should I add ns3 and ns4?

    Hello,

    You should setup NS3/NS4 with their own IP addresses unless you are using an existing DNS cluster, or unless you'd prefer to setup a DNS cluster using the instructions at:

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

    Note that if you prefer to setup a cluster in order to use the same name servers on both cPanel servers, then you'd want to setup an additional server and install cPanel DNS-Only:

    DNS FAQ - Documentation - cPanel Documentation

    Thank you.
