    Hello All,

    I have 3 of 4 of my DNSOnly servers running on EC2 (the fourth is on one of my servers in colo). If I change the EIPs on the DNS servers, will that cause the DNS to break? I was thinking they wouldn't, as they are using hostnames and not IP addresses.

    Thanks :)

    Hello,

    The IP address that's detected when initially adding the server to the cluster is utilized as the name of the configuration file in the following directory:

    /var/cpanel/cluster/root/config/

    I recommend re-adding the DNS-Only server via "WHM Home » Clusters » DNS Cluster" on any hosting servers that use it for clustering after the IP change.

    Thank you.
