Review DNS records
When you add a new site to Cloudflare, Cloudflare automatically scans for common records and adds them to the DNS zone. The records show up under the respective zone DNS > Records page.
The DNS records quick scan is not automatically invoked in the following cases:
- If you choose Enterprise plan and, instead of the Quick Scan, choose to upload a DNS zone file or add records manually.
- If you add a zone via the API.
You can manually invoke the quick scan via API with the Scan DNS Records endpoint.
Note that the quick scan is a best effort attempt based on a predefined list of commonly used record names and types. You can read more about this in the reference page.
Since this scan is not guaranteed to find all existing DNS records, you need to review your records, paying special attention to the following record types:
- Zone apex records (
example.com) - Subdomain records (
www.example.comorblog.example.com) - Email records
If you want more control over which DNS records are imported and how, import a zone file.
