# DNSSEC

Last updated Aug 25, 2026|Copy as Markdown|[View as Markdown](https://4f1c5cd2.previews.developers.cloudflare.com/learning-paths/application-security/default-traffic-security/dnssec/index.md)|[Agent setup](https://4f1c5cd2.previews.developers.cloudflare.com/agent-setup/)

DNS Security Extensions (DNSSEC) adds an extra layer of authentication to DNS, ensuring requests are not routed to a spoofed domain.

For additional background on DNSSEC, visit the [Cloudflare Learning Center ↗](https://www.cloudflare.com/learning/dns/dns-security/).

When you [enable DNSSEC](https://4f1c5cd2.previews.developers.cloudflare.com/dns/zone-setups/subdomain-setup/dnssec/), Cloudflare signs your zone, publishes your public signing keys, and generates your **DS** record.

Note:

Cloudflare automatically adds **DS** records for domains using Cloudflare Registrar or those using `.ch` and `.cz` top-level domains.
