Using one domain for multiple servers

[Doctor]

Does anyone here know how I can achieve this?

For example:

Let us say I have a domain (e.g. doctor.com) and 2 new servers (e.g. Server1 and Server2).

What should be done in order for the config below to work?

For Server1
-------------
Hostname: Server1.doctor.com
Primary Nameserver: NS1.doctor.com
Secondary Nameserver: NS2.doctor.com

For Server2
-------------
Hostname: Server2.doctor.com
Primary Nameserver: NS3.doctor.com
Secondary Nameserver: NS4.doctor.com

Setup domain only on one server, then create A entries for name servers on other servers.

Can you please enlighten me with more details?

I have heard of round-robin DNS setup but not sure how that works even after reading the materials on other sites. I roughly understand the concept but not too sure how I can apply on my 2 servers using WHM.
