Why DNS privacy matters

Plain DNS uses UDP port 53 — every query is visible in cleartext to your ISP, coffee shop WiFi, and anyone on the path. Your ISP can see exactly which domains you visit, even if the web traffic itself is HTTPS.

DNS over TLS (DoT) and DNS over HTTPS (DoH) wrap DNS queries in TLS encryption, hiding the query content from network observers.
