DNS (Domain Name System)

Networking

WebRTC Leak DNS over HTTPS (DoH) DNS Leak

Distributed naming system mapping domains to records.

Definition

DNS resolves domain names into resource records (A/AAAA/CNAME, etc.) via recursive resolvers, and can leak browsing intent through query logs and metadata.

In plain English Distributed naming system mapping domains to records.

Why this matters

Why it matters: DNS metadata is highly revealing and often unencrypted by default, enabling network observers to infer browsing behavior.

Example

Example: Resolver logs of queried domains correlated to a subscriber IP.
