When setting up multiple servers for hosting accounts do you use DNS servers for accounts on each server or do you manage your DNS on one server for all accounts no matter which server they are on?

If you are using Cpanel , then you can surely Cpanel DNS clustered technology where you can keep all the DNS zone running on a single server and keep the web server seperate.
However in traditional hosting every cpanel server keeps its website DNS zones on the same server.

Clustered DNS is easier to work with, but can provide a single source of attack from the outside if not guarded correctly. We use groups of clusters. So for every 10 servers, we have a different set of nameservers, then 2nd & 3rd servers too.

The advantage of a clustered setup is that if you ever need to move a client from one machine to another, it can be done without having to have the client update their domain records.

Thanks guys, I figured there must be a way to do that. I'll research it further then to find more details and how it's done.

cPanel's DNS cluster is amazing. Using cPanel-DNS only and it is free to use it, no license is required.

As already mentioned another server with cpanel dns only on it can be used to offload the dns requests from the cpanel web server

You could also look at round robin dns for when your very large and it's required.

you setup your webserver to offload dns to the dns cluster

each server in the cluster contains exactly the same records as the others in the cluster


with round robin dns you would have

two dns records for your name servers pointing to the same name but different ip's

so request one would server from ns1 (node a) and request two would be served from ns1 (node b) (round robin serves the next in order so 1,2,3,4,5 etc untill it runs out and starts again)
