Relationship between Registrar and DNS Server

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

2registrars enter your domain in the Domain Name Registry (hence the clever name) for the top-level domain your domain exists in (.com, .gov, .edu, etc ). Then you can either host a publicly accessible DNS server yourself, and define a zone within it containing your hosts, or you can often have the registrar host the zone themselves. The registrar will import your zone and include it in a periodic zone transfer up to the tld registry. ISPs DNS servers pull a zone transfer from the tld servers periodically, and thats how other servers learn about the addresses you register. – Frank Thomas – 2016-10-05T03:32:36.153

The comment by @FrankThomas is correct in how the DNS system works; using that, if you want to map whatever.com to an INTRAnet server (e.g. 192.168.1.15), you'll need to host your own DNS server on your network. Further, if you want port 8090 to be the port the server hosts the site on, you'll need to add a rule on the server to look for requests to whatever.com to 192.168.1.15:8090 .. – txtechhelp – 2016-10-05T05:15:20.690
