Cloudflare no relation DNS over TLS
Technology
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.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.
