DNS over HTTPS (DoH)

Networking

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

Encrypting DNS lookups using HTTPS.

Definition

DNS over HTTPS sends your DNS requests through an encrypted HTTPS connection, so local network observers can’t easily see them.

In plain English Encrypting DNS lookups using HTTPS.

Why this matters

Why it matters: It reduces DNS spying on public Wi‑Fi, but your DoH provider may still see queries.

Example

Example: A browser uses DoH to resolve websites through a chosen DNS provider.
