I'm not a big fan of jargon either, but if you clicked on one of those links, you'd see that it stands for DNS over HTTP or DNS over Tor.

TLS, not Tor

The GP's link, the one they maintain, says DNS over Tor.

DoT is DNS over TLS: https://techdocs.akamai.com/etp/docs/configure-dot-doh, https://www.cloudflare.com/learning/dns/dns-over-tls/, https://developers.google.com/speed/public-dns/docs/dns-over..., https://en.wikipedia.org/wiki/DNS_over_TLS

Android ≥ 9 natively supports DNS over TLS: https://android-developers.googleblog.com/2018/04/dns-over-t...

So does iOS ≥ 14: https://developer.apple.com/documentation/networkextension/d..., https://support.quad9.net/hc/en-us/articles/360057889591-Set...

The link you’re referring to, https://github.com/celzero/rethink-app, supports DNS over Tor, but does not call it “DoT”. It does not support DNS over TLS (https://github.com/celzero/rethink-app/issues/441), and it is not something that phones have built-in.

Not sure what you mean, I clicked on the first link before commenting, for "GoodbyeDPI", and learned that it was a "Deep Packet Inspection circumvention utility (for Windows)", I still didn't know what DoT or DoH was, sorry.

Most Android phones... have DNS over Tor... built in? This can't be, can it? I'm pretty confused.

DNS over TLS and DNS over HTTPS.

DNS over TLS.

Android calls it "Secure DNS". It's in the connection settings, I believe starting from Android 9 or 10.

It’s an acronym, of an acronym
