Worldwide DNS record propagation

Cloudflare DNS is powered by the same network as our lightning-fast CDN. We resolve domains with the same 154 data centers that cache our users’ content, making us the fastest DNS provider globally.

DNS changes propagate orders of magnitude faster since we can avoid waiting for DNS TTLs to expire. This means migrating web hosts or switching over to a disaster recovery server happens almost instantaneously.

Built-In DNS Security

Cloudflare DNS is DDoS protection for domain resolution. It sits behind the same 20 Tbps network that protects over 10 million Internet properties from denial-of-service attacks. Cloudflare DNS also comes with built-in load-balancing, automatic failover, rate-limiting, and filtering. Cloudflare also offers DNSSEC to add a layer of trust on top of DNS by providing authentication. Two-factor authentication is available for all plan types.

Customers on the Business plan receive a 100% uptime SLA. Enterprise customers get 2500% uptime SLA.

Easy DNS Management

We make DNS easy. All your domains can be managed through our user-friendly interface or via an API, regardless of where your Internet properties are hosted. We don’t set query limits and can support millions of records in a single domain.

Secondary DNS

Cloudflare can easily be setup as a secondary DNS provider. When records are edited with the primary DNS provider, the corresponding records at Cloudflare are automatically updated.

Primary-Secondary DNS

An existing DNS provider acts as the primary DNS, including management of records and resolution. Record updates are made to the primary DNS provider. Once configured, the primary DNS provider automatically updates Cloudflare’s DNS. Both Cloudflare’s DNS and the primary DNS provider see DNS traffic, with recursive servers deciding which DNS to use.

Hidden Primary DNS

Cloudflare’s DNS acts as authoritative DNS facing the public internet. Administrators configure and manage DNS through an external DNS provider, including management of records and resolution. Once configured, updates are propagated through to Cloudflare’s DNS.

Setting Up Your Authoritative DNS Records

Going Beyond DNS

Once you’re set up on Cloudflare’s DNS service, you can decide to enable additional features. In your DNS record, you’ll be presented with an orange or gray cloud. Orange means that Cloudflare is turned on and your traffic is routing through Cloudflare’s network, which will help your website run faster and block potential web threats such as DDoS attacks and other common web threats.
