For the sake of clarity lets say I have
registrar.com hoster.com myvps.com (my first VPS) s2.myvps.com (my second VPS)
myvps.com to hoster's DNS servers (
Inside the hoster.com's admin panel I created A record pointing my first VPS` IP to myvps.com
Then I created s2.myvps.com zone and created A record that points at my second VPS` IP. It all seems to be working.
1) With that in mind, how wise would that be to run s2.myvps.com as a DNS server so that the users of s2.myvps.com could manage the whole web-site creation process inside the Virtualmin admin panel without the need to write DNS records manually in hoster.com?
2) Regardless of how wise my idea is, how would I do that? Do I just delegate newdomain.com to ns1.s2.myvps.com and ns2.s2.myvps.com and those DNS servers would automatically be found based on A records that I have already created in hoster.com?
