-### CNAME flattening
-
-With CNAME flattening, Cloudflare finds the IP address that a CNAME points to and then returns the final IP address instead of a CNAME record. With Internal DNS, this behavior is applied by default and cannot be turned off.
-
-Cloudflare will try to flatten the CNAME record within the same [DNS view](/dns/internal-dns/dns-views/). If that is not possible, the following will happen:
-
-1. The CNAME record is returned to Gateway resolver as-is.
-2. Gateway resolver will process the returned record, depending on the **Fallback through public DNS** configuration:
-    - On: Gateway will try to resolve the query by sending it to Cloudflare's public DNS resolver ([1.1.1.1](/1.1.1.1/)).
-    - Off: Gateway will return the response as-is to the client.
