What does DoT stand for in the context of DNS security?

• A. DNS over TLS
• B. DNS over TCP
• C. DNS over SSH
• D. DNS over HTTP

Answer: (A)

DNS queries are protected by encryption, wrapping the DNS messages in a TLS layer so privacy and integrity are preserved as they travel from client to resolver. DoT stands for DNS over TLS. It runs over TCP with TLS on top, typically using port 853, so the entire lookup session is encrypted. This prevents network observers from seeing which domains you query or from tampering with responses, unlike plain DNS that often uses UDP without encryption. It’s a privacy-focused option among DNS transports, distinct from DNS over HTTPS, which uses HTTPS as the transport. DNS over TCP simply means DNS over TCP as the transport, not necessarily encrypted with TLS.
