I don't quite get how registrar and DNS server interact.
What happen when I enter mydomain111.org (assuming that i bought it through name cheap and point the DNS server to DO). Is it something like:
Registrar (namecheap) > DNS Server (Digital Ocean) > Mapped Server Record?
I have a application server running in our intranet, I'm thinking of how to access it via mydomain111.org instead of 192.168.1.15:8090
