DNS
The world's fastest and most reliable DNS for free
Cloudflare's Authoritative DNS translates domain names into IP addresses using a massive global network to deliver the fastest, most resilient query responses.
Raw Performance
Consistently measured as one of the fastest authoritative DNS provider in the world. Our massive anycast network responds to queries from a data center physically close to the user, minimizing latency and providing a faster start to every application connection.
Unmatched DDoS Resiliency
Our network is one of the largest in the world and is designed to mitigate the largest DDoS attacks. Developers using our DNS don't have to worry that an attack will take their application offline at the resolution level.
Free, Fully-Featured API
Unlike competitors who may charge for API access or have limited functionality, our DNS is free and completely controllable via a rich, well-documented API. This enables true Infrastructure-as-Code for developers using tools like Terraform and Ansible.

Authoritative Records
Serving as the fast, reliable, and secure "phonebook" for a company's primary website and API endpoints (managing their A, AAAA, and CNAME records).Automated Validation
Automating service validation by programmatically creating and deleting TXT records for things like SSL certificates, Google Search Console, or Microsoft 365.Instant Propagation
Dynamically routing millions of users with super fast propagation to steer traffic to the least-loaded backend, without traditional load balancers.Internal DNS
Private DNS, unified with your public DNS. Define internal zones, run split-horizon DNS without configuration drift, and extend private name resolution to remote users and any cloud.BigScoots
Managed WordPress host BigScoots moved all client zones to Cloudflare DNS cutting average lookup time to 11ms and achieving global record propagation in under five seconds, all while fully automating onboarding through our API.
Powerful primitives, seamlessly integrated
Built on systems powering 20% of the Internet, DNS run on the same infrastructure Cloudflare uses to build Cloudflare. Enterprise-grade reliability, security, and performance are standard.
