Get started with Cloudflare DNS

Enterprise-grade authoritative DNS service that offers the fastest response time, unparalleled redundancy, and advanced security with built-in DDoS mitigation and DNSSEC. [Learn more]

[Begin DNS transfer]

Once the DNS transfer is complete, you’ll be able to add this Custom Domain to your Pages project.

However, when I follow the instruction, it eventually admits I already have CF managed the DNS of this domain.
