Fun with DNS over TLS (DoT), (Mon, Mar 1st)

Going back a few weeks, we discussed how DNS over HTTPS (DoH) works (https://isc.sans.edu/forums/diary/Fun&#;x26;#;x2b;with&#;x26;#;x2b;NMAP&#;x26;#;x2b;NSE&#;x26;#;x2b;Scripts&#;x26;#;x2b;and&#;x26;#;x2b;DOH&#;x26;#;x2b;DNS&#;x26;#;x2b;over&#;x26;#;x2b;HTTPS/27026/)&#;x26;#;xc2;&#;x26;#;xa0; - very much as an unauthenticated API over HTTPS.&#;x26;#;xc2;&#;x26;#;xa0; But DNS over TLS (DoT) has been with us for a fair bit longer (May 2016), why haven&#;x26;#;39;t we heard about it so much?
