Cloudflare DNS Application

Application Information

The following page provides details on domains, networks, IPs, hosting services, and content delivery networks used by Cloudflare DNS.

Description

Cloudflare provides DNS services including the well known 1.1.1.1 public DNS server. Controversially, the company also offers DNS over HTTPS/TLS. This protects end user privacy from nosy ISPs, but also circumvents DNS policies on local networks.

Domains

Primary Domains

Primary Domains are owned and managed by the application vendor.

Platform Domains are often provided by hosting providers, content delivery networks, SaaS platforms and other third parties. It is important to identify these domains for DNS filters and hostname blocklists.

Content Delivery Networks - CDNs

In order to get information to end users more quickly, many applications are distributed from multiple geographical points-of-presence (PoPs) using Content Delivery Networks (CDNs). Each PoP can host many IPs to deliver an application. A sample IP is provided.

Take special note of CDNs that use Anycast technology. Anycast makes it possible to route a single IP address to a variety of different geographic locations. In other words, one global Anycast IP is hosted in multiple geographic locations.
