I have a new VPS I want to use to manage sites on. I need to set up nameservers so that I can point the domain names to the new servers. I know nameservers usually look like ns1.example.com where example.com is the domain name of the VPS, but my VPS does not have a domain name, I just access it via the servers IP.
Is it OK to use a domain name of one of the sites I am trying to set up instead?
Nameservers can have DNS records for other domains too. For example:
ns1.abccompany.com and ns2.abccompany.com provides DNS for:
The nameservers (ns1.abccompany.com and ns2.abccompany.com) need to be setup in your DNS settings for abccompany.com, and then set the same nameservers in your other domains, along with the "A" record indicating which IP address these would be served from.
So yes, you can use one domain to act as the nameservers for the others.
