!!! Overview[1]
[{$pagename}] ([DoH]) is an experimental [protocol] for performing remote [Domain Name System] ([DNS]) resolution via the [HTTPS] [protocol].
[IETF] set up a [{$pagename}] [Working Group] will standardize encodings for [DNS] [Request] and [responses] that are suitable for use in HTTPS. This will enable the domain name system to function over certain paths where existing [DNS] methods ([UDP], [TLS] [RFC 7857], and [DTLS] [RFC 8094]) experience problems.
The goal of the method is to increase user [privacy] and security by preventing [eavesdropping|Eavesdropper] and manipulation of [DNS] data by [Man-In-The-Middle] attacks. As of March [2018|Year 2018], [Google] and the [Mozilla] Foundation are testing versions of [{$pagename}]
[{$pagename}] [Working Group] produced an [Internet Draft] [https://tools.ietf.org/html/draft-ietf-doh-dns-over-https-14|https://tools.ietf.org/html/draft-ietf-doh-dns-over-https-14|target='_blank']
!! [Mozilla] and [{$pagename}][3][4]
[Mozilla] has done work and has presented an [Internet Draft] [DNS Queries over HTTPS] ([DoH]). September 6, [2019|Year 2019] Mozilla quietly announced a major change to its [Firefox] web [browser], explaining that "after many experiments—we feel confident that enabling [DoH] ([{$pagename}]) by default is the right next step."
!! [Google] [{$pagename}]
[Google]'s publicly-implemented version of this protocol uses [HTTP GET] commands (over [HTTPS]) to access [DNS] information using an encoding of [DNS] query and result parameters represented in [JSON] notation.[2]
