DNS over TLS (DoT) — DNS over TLS, a protocol that protects DNS traffic with a dedicated TLS connection, conventionally on TCP port 853.
The mechanism changes how DNS queries are transported or processed; it does not make incorrect DNS data correct. Encryption protects the channel to the selected resolver, while answer integrity and logging policy depend on that resolver and DNSSEC.
DNS over TLS (DoT) — DNS over TLS, a protocol that protects DNS traffic with a dedicated TLS connection, conventionally on TCP port 853.
It changes the transport, processing point, or local caching behavior of a DNS query. This can improve privacy and control, but it also affects filtering, troubleshooting, and resolver selection.
Verify the resolver endpoint and trust model, client support, network policy, fallback path, and logging. Separately confirm where DNSSEC validation is performed when it is required.
