We would like to offer VPS servers with cpanel. My plan was, that each vps has one IP address. On this IP address the customer run a own nameserver (ns1) with cpanel.
As a 2nd nameserver I thought I could use dnsonly and set the dnsonly server to standalone for all VPS servers. On the VPS self I choosed "synchronise changes" to the dnsonly server.
I hope you know what I mean, at the end each customer would use nameservers like this:
But the problem is, that now every customer can see all dns zones of the other customer when he click on "edit dns zone" in whm.
What is wrong in my idea? Or how do you sell VPS with cpanel and offer a 2nd nameserver offserver?
