What is DNS over TLS (DoT)?

Explanation:
DNS over TLS is about wrapping DNS queries in a TLS session so the communication between a client and resolver is encrypted and protected from eavesdropping or tampering. It uses a dedicated TLS port, typically 853, to keep DNS traffic separate from ordinary web traffic. This is what makes DoT different from plain DNS (which is unencrypted) and from DNS over HTTPS, which runs DNS queries over HTTPS on port 443. It’s not about signing DNS records (that’s DNSSEC), transferring zone data, or prioritizing queries.
