# DNS

> Cloudflare's Authoritative DNS translates domain names into IP addresses — using a massive global network to deliver the fastest, most resilient query responses.

## Key Features

- Fastest authoritative DNS
- Global anycast network
- DDoS protection
- Free API access
- Fast propagation
- Terraform support
- DNSSEC support

## Benefits

### 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.

## Use Cases

### 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.

### Infrastructure as Code

Managing DNS records programmatically with tools like Terraform and Ansible, enabling true Infrastructure-as-Code workflows for modern development teams.
