[HDGEM] Cloudflare uses CNAME Flattening to present a CNAME as an A record.

The Cloudflare server generating the response follows the CNAME chain so that the response to the request from the client (for example, the browser) contains only non-CNAME data -- usually, an IP address. This effectively creates an A or an AAAA record. Without flattening, Cloudflare would serve the CNAME record directly to the recursor (the DNS resolver that translates the domain name to an IP address).
