How do I assign my domain to a DNS running on my virtual server?

In order to have your domain managed by your own DNS server you have to do the following:

1. Register your DNS server. Usually the registrar of your domain will provide this service for you.
2. Point the domain to your DNS server.
3. Add the domain to your nameserver configuration and reload the zones.
4. Wait up to 48 hours for the changes to propagate.
