Set up CNAME flattening
For your zone apex
CNAME flattening occurs by default for all plans when your domain uses a CNAME record for its zone apex (example.com, meaning the record Name is set to @).
For all CNAME records
Accounts on paid plans can also choose to flatten all CNAME records on their domain. This option is useful for DNS-only (unproxied) CNAME records since proxied records are flattened by default (as they return Cloudflare IPv4 and IPv6 addresses).
- Log in to the Cloudflare dashboard and select your account and domain.
- Navigate to DNS > Settings.
- For CNAME Flattening, select Flatten all CNAMEs.
