1.1.1.1 sees approximately 600 billion queries per day, with most being sent over cleartext UDP and TCP. To improve end-user privacy, the adoption of encrypted protocols such as DNS-over-TLS or DNS-over-HTTPS is encouraged. Discovery of Designated Resolvers (DDR) is a mechanism that allows clients to automatically upgrade non-secure connections to secure ones. 1.1.1.1 now supports the latest version of DDR, enabling more encrypted DNS on the Internet and helping with standardization efforts.
