Understand the roles
- The registrar keeps ownership of the domain.
- Cloudflare may host DNS and proxy website traffic.
- The origin host still stores the site unless Cloudflare Pages is used.
Useful Cloudflare services
- Caching can speed delivery of static assets.
- HTTPS and security rules protect normal web traffic.
- Workers can run small server-side tasks such as secure form handling.
Avoid common mistakes
- Do not proxy records that a mail provider requires to remain DNS-only.
- Preserve MX and authentication records during migration.
- Keep account recovery, API tokens, and administrator access protected with MFA.
