The 1.1.1.1 DNS service operates recursive name servers for public use at the twelve IP addresses listed below. These addresses are mapped to the nearest operational server by anycast routing. The DNS service is also available for Tor clients. Users can set up the service by manually changing their DNS resolvers to the IP addresses below. Mobile users on both Android and iPhone have the alternative of downloading the 1.1.1.1 mobile application, which automatically configures the DNS resolvers on the device.
1.1.1.1 is a recursive DNS resolver. Cloudflare runs an authoritative DNS resolver with a network of over 20 million Internet properties. With the recursor and the resolver on the same network, some DNS queries can be answered directly.[independent source needed]
With the release of the 1.1.1.1 mobile application in November 2018, Cloudflare added the ability for users to encrypt their DNS queries over HTTPS (DoH) or TLS (DoT). Later on, a VPN tunnel was implemented based on Cloudflare's own BoringTun, a user space implementation of WireGuard written in Rust.
WARP+ routes users' internet traffic into less congested pathways using Cloudflare's own private backbone called Argo, which makes it much faster than basic WARP. WARP+ is a limited data plan, to get more data to use WARP+, users must refer more people to use the service.[34]
WARP+ Unlimited is a paid monthly subscription service to secure more data to use for WARP+ without any data limits.[34]
