The first dedicated server I setup two custom nameserver at registrar to server 1 ips and set the whole domain to those two namservers. (lets just say my domain is server.com)
ns1.server.com
ns2.server.com
I now want to add a second dedicated server ie:
ns3.server.com
ns4.server.com
But I don’t want to route DNS through server1, which I would have to do with the current setup.
How do the big hosting companies do this - where they have hundreds/thousands of nameservers on a single domain?
EDIT: Hosting companies can have hundreds/thousands of "pseudo" nameservers (example:ns124.server.com) which are basically A records. My original statement/question above was wrong, but was referencing what I was trying to achieve with my understanding at the time.
Any help would be appreciated.
