CNAME Redirect

[jacobdavie7]

Currently, my root domain redirects you to my Github page. I want to use a CNAME record to create github.mydomain.com and have that take you to my Github. However, you can’t just put in the IP address of the A record into a CNAME. I also can’t just put the direct link to my Github in the CNAME. Once this is done, I don’t want my root domain to go anywhere, so I can’t have github.mydomain.com point to my root domain. What am I missing here? How would I get this accomplished?

Also, side question, why does going to the IP address that your A record points to not work?

Thank you very much!

If you want to simply redirect to the GitHub page create an A record for github.example.com that points to a bogus IP (192.0.2.1 is a good one), make it proxied and create a Page Rule for github.example.com/* that forwards to where you want.

Mainly because the Cloudflare IPs are not dedicated to your DNS entries. Every Cloudflare IP will actually work for any domain (you can override the DNS in your hosts file if you want to test this.) It also limits Cloudflares ability to manage their infrastructure as they need to.
