Overview

Cloudflare’s mission is to be the fastest, most resilient, and simplest managed DNS platform to meet our customer’s and partner’s DNS needs.

​​ Benefits

When you use Cloudflare DNS, all DNS queries for your domain are answered by Cloudflare’s global Anycast network. This network allows us to deliver excellent performance while guaranteeing global availability.

Our Anycast network also allows us to mitigate DDoS attacks directed at any site using Cloudflare nameservers, whether they are paying us a lot or nothing at all.

Beyond these benefits, Cloudflare authoritative DNS also provides free DNSSEC and protects against route leaks and hijacking.
