Two level subdomains with Github pages

Question

I want to have a github pages site that has two subdomains. It would look something like this: www.example.example.com. Is it possible to do this? What DNS records would I need? I already was able to set it up with one subdomain, but I can't figure out how to add the www subdomain.

Answer 1

I was able to resolve this by setting up subdomain forwarding with my DNS provider. For example, www.example.example.com forwards to the site example.example.com where the github pages site is hosted. This feels like not a real solution, but it seems to work.
