DNS Security Extensions (DNSSEC) adds an extra layer of authentication to DNS, ensuring requests are not routed to a spoofed domain.
Your DNSSEC setup can be different depending on where you registered your domain name:

- Find the domain you where you want to activate DNSSEC and select Manage.
- Select Configuration > Enable DNSSEC. If DNSSEC was previously activated, select Disable DNSSEC to disable it.
Cloudflare publishes delegation signer (DS) records in the form of for a domain delegated to Cloudflare. Cloudflare Registrar scans those records at regular intervals, and gathers those details and sends them to your domain’s registry.
This process can take one to two days after you first enable DNSSEC.
First, activate DNSSEC in the Cloudflare dashboard:
- Log in to the and select your account and domain.
- Go to DNS > Settings.
- For DNSSEC, click Enable DNSSEC.
- In the dialog, you have access to several necessary values to help you create a DS record at your registrar. Once you close the dialog, you can access this information by clicking DS record on the DNSSEC card.
You now need to add a DS record to your registrar. If Algorithm 13 - Cloudflare’s preferred cipher choice - is not listed by your registrar, it may also be called ECDSA Curve P-256 with SHA-256.
