Is a CNAME record public

For example, I have a GitHub Pages site with a custom domain.
Here are the dns records for the domain: enter image description here
Is this CNAME record public?
Or is there a way for someone to determine the GitHub Pages url, ajzbc.github.io, from my custom domain ajzbc.com

To clarify, is there for example a command I could run that would output the CNAME?

Thanks

Solution

  • For main domain : dig ajzbc.com

    For www subdomain : dig www.ajzbc.com
