I have bought the domain server-1.eu and want to use it as the url for this blog instead of the current subdomain for github.io. Lets see how we can set it up.

How to configure the DNS?

After some searching in the Github documentation I found some information on how to: Managing a custom domain for your GitHub Pages site

At first I was not sure what an Apex domain was, so I hade to ask ChatGPT:

An Apex domain (or “root domain”) is the highest level of a domain name without any subdomains or prefixes. For example, in example.com, “example.com” is the apex domain, whereas www.example.com includes a subdomain (www). Apex domains are often used in DNS configurations to point to the primary location of a website.

At my domain name provider (GoDaddy) I opened up the DNS setting for my new domain.

I setup configurations for A, AAAA and CNAME:

Type	Name	Value
A	@	185.199.108.153
AAAA	@	2606:50c0:8000::153
CNAME	www	server-1.eu

• The A records with name @ maps the root domain server-1.eu to the ip 185.199.108.153, where the IP points to Github Pages servers.
• The AAAA does the exact same thing but for IPv6.
• The CNAME entry routes the subdomain www.server-1.eu to the root domain server-1.eu.

This is all configuration that is needed for the DNS.

How to configure Github Pages?

I headed over to Github and opened up “Pages” under settings for my david-nossebro.github.io repository. There I found a field to configure a custom domain. After entered server-1.eu and clicket save it took some time for it to go through, and then I could also check the box for enforcing HTTPS:

An now to the final test. Is the page showing up when browsing to server-1.eu?

It works, I now have my own place at the world wide web! 🕸️
