Using custom subdomain for Github Pages website

Here’s how to configure at both Github and Namecheap to use your own custom subdomain (for e.g., https://my.internet.life) to serve a Github Pages website.

At Namecheap

1. Click on Manage for your matching domain.

2. Click on Advanced DNS. Under the “Host Records” section, Add New Record.

3. Select “CNAME Record”, enter the following.

   Host: <your subdomain only> e.g., www or my
   Value: <github-user-id>.github.io (NC will append a dot/period after saving)
   

4. Save the record.

Important: If you’re only using the subdomain, this is the only entry that you’ll need!

At Github

1. Select your repository. Click on ⚙️ Settings (top menu).

2. Click on Pages and enter your custom subdomain in under Custom Domain. For e.g., my.internet.life (without the http/https).

3. Wait for the DNS Check to complete. Once it’s done, a certificate will be provisioned for use and you can enable the Enforce HTTPS.
