DNS over HTTPS (DoH)

Networking

TLS (Transport Layer Security) HTTPS DNS (Domain Name System)

DNS queries transported over HTTPS/TLS.

Definition

DoH encapsulates DNS messages in HTTPS requests, providing transport encryption and integrity against on-path observers.

In plain English DNS queries transported over HTTPS/TLS.

Why this matters

Why it matters: It mitigates local monitoring and manipulation of DNS, but shifts trust to the chosen resolver.

Example

Example: RFC 8484 DoH endpoint used by a browser or OS.
