DNS-over-TLS (DoT) cifra las consultas [[dns|DNS]] usando el protocolo TLS en un puerto dedicado (853). A diferencia de [[dns-over-https|DoH]], DoT usa su propio puerto, lo que facilita a los administradores de red identificar y gestionar el tráfico DNS.
Ejemplo
Android 9+ supports 'Private DNS' which uses DoT to encrypt DNS queries to providers like dns.google or 1dot1dot1dot1.cloudflare-dns.com.
