Disappearing DNS: DoT and DoH, Where one Letter Makes a Great Difference

(February 6, 2020)

While both offer encryption of DNS data using the same TLS protocol, there are some very important differences:

– Protocol layering: while DoT is essentially DNS over TLS, DoH is in fact DNS over HTTP over TLS.
– Different port numbers: DoT traffic uses a dedicated port 853, and can thus be distinguished at the network layer. DoH uses port 443 (HTTPS) due to the protocol layering.
– Different capabilities: DoT is largely the same DNS as we know it, while DoH to an extent combines features of DNS and HTTP.

Disappearing DNS: DoT and DoH, Where one Letter Makes a Great Difference

(06.02.2020)

Obviously, time will tell if DoT continues to prevail or whether DoH will start to gain ground. As mentioned at the beginning of the article there is a hot debate going on right now about the direction the Internet industry should take. Suffice to say that even nation state authorities are involved in the debate, which speaks to the level and importance of the discussion.

DNS over TLS FritzBox aktivieren

DoT ist letztlich nur ein weiterer Schritt die Privatsphäre zu schützen. Diese Technik verschlüsselt nur die Strecke vom heimischen Router bis hin zum Resolver des Anbieters.

Fritzbox und DNS-Verschlüsselung: Analyse mit Wireshark

^(23.10.2020)

Alle Geräte, die Internet-fähig sind, ermitteln mit DNS-Anfragen die IP-Adressen von Servern, um diese ansprechen zu können. Das ist etwa der Fall, wenn ein Browser die Domain ct.de ansteuert – der konfigurierte DNS-Resolver, meist der des Providers, liefert dann die IP-Adresse 193.99.144.80. Diese ruft dann der Browser auf, um eine HTTP-Verbindung zum Server aufzubauen. Weil die Geräte solche Anfragen unverschlüsselt und täglich vielfach an Resolver versenden, können fremde Nachrichtendienste oder Spione Profile von Nutzern erstellen.

Was ist DNS over TLS (DoT)?

DNS over TLS (DoT) ist ein Protokoll zur verschlüsselten Übertragung der DNS-Namensauflösung. DNS-Anfragen und DNS-Antworten sind dadurch vor dem unbefugten Mitlesen und vor Manipulationen geschützt.

Mozilla: ISPs Are Lying About Encrypted DNS, Should Have Privacy Practices Investigated

The effort would effectively let Chrome and Mozilla users opt in to DNS encryption — making your browser data more secure from spying and monetization — assuming your DNS provider supports it. Needless to day, telecom giants that have made billions of dollars monetizing your every online behavior for decades now (and routinely lying about it) don’t much like that.

As a result, Comcast, AT&T, and others have been trying to demonize the Google and Mozilla efforts any way they can,

DoH is an over the top bypass of enterprise and other private networks. But DNS is part of the control plane, and network operators must be able to monitor and filter it. Use DoT, never DoH.
