I own a custom domain through GoDaddy.com that I want to use for my user page at arsturges.github.io.Github.io offers a neat, free hosting option. I had no trouble setting up a site at arsturges.github.io, but I found the custom URL documentation to be unclear. Below, I’ll explain how I set up my github.io user page with my GoDaddy.com domain name andrewsturges.com.

In brief, the steps are as follows:

  1. Set up my user page arsturges.github.io
  2. Commit a file called CNAME with one line: andrewsturges.com
  3. Go to GoDaddy site to manage my URL
  4. Add an “A (Host)” record with “host” = @ and “Points to” = 192.30.252.153
  5. Add a “CNAME (Alias)” record with “host” = www and “Points to” = arsturges.github.io
  6. Wait for changes to propogate.

Below i’ll go over these steps in detail.

1. Set up your user page at gitub.io

I’ll asume this is done. In my case, I set up a user page at arsturges.github.io. When I navigated to that page, the URL stayed as asturges.github.io (i.e., it didn’t redirect to anywhere).

2. Commit a CNAME file

I added a file called CNAME (all caps, no extension), with a single line andrewsturges.com. CNAME file as seen on Github

3. Go to Godaddy.com and set up two records

On the github.io custom URL instructions, this part wasn’t clear to me. For my page, I had to set an A record and and Alias record. First, navigate to the page where you can manage the domain that want to point to your github.io page. From there, click on the “DNS Zone File” tab to add records.

4. Create an A record

Add a single A record that points to 192.30.252.153. This is explained at https://help.github.com/articles/tips-for-configuring-an-a-record-with-your-dns-provider/

GoDaddy A record

5. Create a CNAME record

Add a single CNAME record as follows:

GoDaddy CNAME record

That’s all I did with GoDaddy. I didn’t change anything else, including the Nameserver (NS) records.

6. Wait for changes to propogate

When the DNS updates, you should be able to navigate to your custom domain and see your pages.github.io page. You can check your work with the following command, and compare to my results:

$ dig andrewsturges.com +nostats +nocomments +nocmd

; <<>> DiG 9.10.3-P4-Ubuntu <<>> andrewsturges.com +nostats +nocomments +nocmd
;; global options: +cmd
