Get a domain name

Instead of writing your public IP, someone might want to reach your server using something more human friendly : a domain name.

What is a domain name ?

One can register a domain, i.e. "something-cool.tld" as a sign pointing to your IP address. When an human enter "something-cool.tld", the computer will ask the registrar what IP is behind this sign to reach it. In this case, the domain is resolved.

It is easier to remember, it gives identity to your project, and it let you organise it using subdomains (webmail.athome.tld, cloud.athome.tld...).

Below is a little comic to explain a DNS query :


You can find free registrar, or rent a domain name. There are many registrars out there. I've been happy with these ones, especially GANDI because it's self-hosting friendly :
