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
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?
