Setting up a nameserver for a public domain works the same way as setting up a DNS server for an internal hostname, just with a few additional parts that we'll want to make sure are in a good state.

How to do it...

Let's set up a nameserver for a public domain:

   ) 

2. Set up a record for NS hosts:
