I have one ubuntu server running in a specific ip address. Multiple apps are running with the help of gunicorn and nginx. I can access all those apps after editing the '/etc/hosts' file in my local machine.
Then, I bought a domain name. Now, the problem I'm having is to point my domain name to my ip address of the server.
I contacted the domain provider but they told me 'for custom name server you need to contact your hosting provider to point A record on your branded name server'. This went over my head, as I'm not familiar with these.
I researched a bit and found the use of 'BIND' but I'm not 100% sure. I don't want to end up breaking my server. So, what do i do?
