DNS Encryption Explained

The Domain Name System (DNS) is the address book of the internet, translating domain names into IP addresses. However, DNS queries and responses are typically unprotected, posing privacy and security risks. Encrypting DNS can improve user privacy and security. Two mechanisms for encrypting DNS exist: DNS over TLS (DoT) and DNS over HTTPS (DoH). Both are based on Transport Layer Security (TLS), which is also used to secure communication between a web server and client using HTTPS. Encrypting the web has made it possible for private and secure communications and commerce to flourish, and encrypting DNS will further enhance user privacy. Major public resolvers support DoT and DoH, but many ISP resolvers still lack support for them.
