I know of domain name registrars, that you can use them to acquire your own domain name for a website; but, how do they connect to the internet and email (servers) globally?
I'm not exactly sure how to better word that.
Say I register example.com. What's actually going on here? Is there some master list of servers somewhere that your registrar updates, so that when people enter it into their browsers these servers will redirect your domain name to your website's server IP?
The main reason I ask this and am curious about it, as a programmer, is in regards to emails. How does [email protected] actually work? Who's in charge of managing that email, and what if someone else buys example.com 5 years from now? Could I host my own email address at home if I own a domain name, and would I want to do that?
