DNS over HTTPS, DNS over TLS, DNS over QUIC: Encrypted DNS Protocol Comparison
Encrypted DNS protocols are designed to secure DNS queries that are typically sent in plain text. This article compares four main protocols: DNS over HTTPS, DNS over TLS, DNS over QUIC, and DNS over HTTPS/3. It provides insights into their performance, privacy, and compatibility to help website owners choose the right option for their needs.
- ▪DNS queries are sent in plain text by default, exposing them to monitoring by ISPs and attackers.
- ▪Encrypted DNS protocols wrap queries in a secure transport layer to enhance privacy and security.
- ▪The article compares DNS over HTTPS, DNS over TLS, DNS over QUIC, and DNS over HTTPS/3, highlighting their differences and use cases.

Opening excerpt (first ~120 words) tap to expand
You already know that DNS translates domain names into IP addresses — the internet’s phone book, as the classic analogy goes. If you want a refresher on how DNS works at its core, our introduction to DNS covers the fundamentals.But here is something most website owners don’t know: every DNS query your visitors make is sent in plain text by default. That means your ISP, network administrators, and anyone monitoring the connection can see exactly which domains are being resolved — even when the page content itself is protected by HTTPS. This is the problem that encrypted DNS was designed to solve.In practice, there are four protocols that replace unencrypted DNS: DNS over HTTPS (DoH), DNS over TLS (DoT), DNS over QUIC (DoQ), and DNS over HTTPS/3 (DoH3).
