Github Solutions
Solution 1 - Github
No, this is not possible. See the GitHub Help docs that explain this:
> Ensure you only have one domain listed in your CNAME file. If you wish to have multiple domains pointing to the same Pages, you will need to set up redirects for the other domains. Most domain registrars and DNS hosts offer this service to their customers.
Solution 2 - Github
Here is one approach that is a Github-only solution using an HTML redirect.
- Create an extra repository
- Configure it to use Github Pages with the additional domain
- Add an an
index.htmlfile with the following contents
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Redirecting to https://example.com</title>
<meta http-equiv="refresh" content="0; URL=https://example.com">
</head>
<link rel="canonical" href="https://example.com">
</html>
Solution 3 - Github
You can have only one domain name in the CNAME file. Additionally you can setup forwarding (optionally with masking) on your other domains.
Without masking, it is like a redirect to your original website where the url in the browser will show your original website.
With masking, it will serve contents from your original website and the url in the browser will show the new one.
I have setup forwarding with masking for my blog. You can check out the following links to see how that works.

Forwarded blog: http://batcode.net
Solution 4 - Github
Only one DNS record is needed to point reggi.com OR www.reggi.com to username.github.io.
Github automatically points both to username.github.io
With the above set you can reach username.github.io/blog at:
blog.reggi.com (with CNAME file containing blog.reggi.com) or reggi.com/blog or www.reggi.com/blog
or even
blog.reggi.com/blog (with CNAME file containing blog.reggi.com)
Hope this helps. It was beyond me for a while.
Solution 5 - Github
What Ivan Zuzak says. If you want to redirect blog.reggi.com to reggi.com, you can't do this from Jekyll's CNAME file. However, as indicated in the documention, your domain registrars should be able to do this for you.
For example, I use the domain from name.com, I can add one "URL Forwarding" entry:
Domain blog.xxx.me
URL xxx.me
Type Redirect (301)
It should take effect within short period of time (an hour or two for me).
Solution 6 - Github
if you are using cloudflare, you can use Page Rules to redirect your url to github pages.
check this page: Configuring URL forwarding or redirects with Cloudflare Page Rules – Cloudflare Support
Solution 7 - Github
No, but you could use a GitHub Action to keep a second repo up-to-date with the master repository. This second repo could have GitHub Pages set up with another domain.
Fork Sync looks like a good option.
