Cloudflare CNAME Flattening
We can use a CNAME record at our root/apex domain with Cloudflare CNAME flattening, which speeds up CNAME resolution. Let’s take a closer look at Cloudflare’s CNAME flattening. To discover the IP address that a CNAME points to, Cloudflare uses CNAME flattening. Single or multiple lookups may be used in this procedure (if your CNAME points to another CNAME). Instead of a CNAME record, Cloudflare returns the final IP address, which accelerates DNS query resolution
