Hi,

we currently have a dns only cpanel VPS manaing our second name server.
We received a new VPS with a new IP and have installed Cpanel DNS only.

Currently we sync chnages to the dns only server. The dns only server is set to standalone.
We would like to use new server with the new IP now for your second name server.

What is the best way to do this? Anything we have to look out for?
Should we remove the old dns only server and then add the new one? Or add the new one first, then remove the old one?

If we change the IP of the second nameserver on our server, will it make changes to all the domains to use that new IP and then sync it to the new DNS only server?

Thanks :)

Hello :)

You can simply configure the new DNS-Only server the same way you configured the first one. The cluster configuration guide is found at:

Configure Cluster

You can then disable the original DNS-Only machine and remove it from the "Configure Cluster" screen.

If we change the IP of the second nameserver on our server, will it make changes to all the domains to use that new IP and then sync it to the new DNS only server?
Name server IP addresses are handled at the domain registrar of the domain name the name server is associated with. You can modify the IP address of a name server at the domain registrar, and then update the "A" record on the cPanel server. Then, all domain names that use those name servers at their registrar will automatically use the new IP address.

Thank you.

Thanks @cPanelMichael

Yes, it clear to me that the IP chnanges happen on the registrar side. I was asking if the loca cPanell server will update the domains in the DNS to use the new IP. I mean literally on the server :)

If you look at the DNS Zones of the domains in your server, you see the name server entries like:
domain.com. 86400 IN NS ns1.nameserverdomain.com.
domain.com. 86400 IN NS ns2.nameserverdomain.com.

so there are no IP addresses of the name servers in the DNS zones.

Only in the DNS zone of the domain nameserverdomain.com you change the IPs of those name servers.
