We have a github repository which is configured to point to nordible.com:
Hitting nordible.github.io successfully lands to nordible.com.
So, we've successfully connected a github website to a custom domain!
The domain nordible.com is with GoDaddy.
Now, what steps shall we take at GoDaddy side to make nordible.com show the pages from nordible.github.io?
We noticed that, there are ways to redirect a domain to a specific Github page. However, we need a direct non-redirecting way of doing this?
It looks like you want the canonical site to have no www. Github publishes step by step instructions for that case. If you do want the www, those instructions are here.
It basically boils down to pointing the domain name to github's IP address. You can set up an A record with 192.30.252.153 or 192.30.252.154.
Instructions for adding an A record to GoDaddy's DNS can be found here: https://www.godaddy.com/help/add-an-a-record-19238
You can't use a CNAME without the www because it will break email for the domain. MX records get ignored if there is a CNAME record at the apex.
I don't think that GoDaddy supports ALIAS records. Those are basically proxy records where you put in domain name to treat like a CNAME, but the DNS provider looks up the IP address, caches it for a few minutes, and serves it as an A record. If you want to use an ALIAS record, you would have to switch to a DNS host that supports them such as Amazon Route 53.
