Diversify DNS using cPanel/WHM? Impossible?

[bcvnbhjag]

One thing that has always puzzled me. It seems as if it is a necessity to host DNS records locally, using the DNS system via WHM, if you want to give your hosted customers full facility to add sub-domains, etc. and this is fine. But what about putting ns1.host.com and ns2.host.com on separate servers? This is recommended over and over again by various DNS testing systems, yet if you do this using cPanel, and if traffic ever falls over to the ns2.host.com (off server) name server, then all the added local DNS record additions go null. You know, those DNS CNAME additions that are created when you input a new sub-domain or addon domain using cPanel, etc.

Those DNS record additions are of course only added to the local server where ns1.host.com points, but not to ns2.host.com. Thus my question: How can you realistically diversify DNS, and make this work when using cPanel?

Have you tried the DNS clustering feature?
