So I recently bought a VPS (virtual private server) from eoreality.net (seriously great hosting from them btw. reliable and very competitively priced). And I didn't want people to have to type in the IP every time to connect to it. So, for the exact same reason that domains were created, I got a domain.
My problem was I didn't how to get the domain to say 'go to this IP.' For that you need to adjust your domain's A (alias) DNS Records. The actual step-by-step part is going to differ depending on your domain registrar, but you're looking for something that mentions DNS records (again, specifically the A records). Change the abc123.com to the IP of your recently purchased VPS and you should be set. Be sure to wait a decent while as the registrar sends word to all the other DNS servers of the name change.
Another cool thing is you can change the subdomains to unique IPs. So I now have mumble.abc123.com pointing to a different IP than www.abc123.com
*At this point I should note that I'm not the owner of abc123.com, and that domain is being used as a generic placeholder.
