I currently have a couple of subdomains to my domain, managed by Bluehost.
If I follow the Cloudflare instructions, and point my nameservers away from Bluehost to Cloudflare, how does Cloudflare “know” how to handle this properly?
At the most basic level, the How It Works says that Cloudflare passes requests on to my original website’s IP - how does it know that IP?
And what if the subdomain that the request came on is a redirect (CNAME) handled by Bluehost?
Does all this “just work”?
