How to create your own ns servers?

Question

DigitalOcean

There is a server on digitalocean and there are 15 sites that need to be transferred there (there is also a vestacp panel).
So here's how to create ns1.mydomain.com and ns2.mydoamain.com types and hang all other sites on them (otherwise each one on digitalocean will not be convenient for a long time).
It is desirable to tell in the context of vestacp + digitalocean.

Answer 1

On DO, you raise 2 VDS in different data centers, set, for example, bind, create a zone, but the domain settings at the registrar must also specify IP in addition to the uri address.
