DNS-over-TLS (DoT)

DNS-over-TLS (DoT) encrypts [[dns|DNS]] queries using the TLS protocol on a dedicated port (853). Unlike [[dns-over-https|DoH]], DoT uses its own port, making it easier for network administrators to identify and manage DNS traffic.

Example

Android 9+ supports 'Private DNS' which uses DoT to encrypt DNS queries to providers like dns.google or 1dot1dot1dot1.cloudflare-dns.com.
