DNS over TLS (DoT) is a security protocol for encrypting and wrapping Domain Name System (DNS) queries and answers via the Transport Layer Security (TLS) protocol. The goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data via man-in-the-middle attacks.

As of 2019, Cloudflare, Quad9, Google, Quadrant Information Security and CleanBrowsing are providing public DNS resolver services via DNS over TLS.[1][2][3][4][5] In April 2018, Google announced that Android Pie will include support for DNS over TLS.[6] DNSDist, from PowerDNS also announced support for DNS over TLS in its latest version 1.3.0.[7] BIND users can also provide DNS over TLS by proxying it through stunnel.[8] Unbound supports DNS over TLS since 22 January 2018.[9][10] Technitium DNS Server supports DNS over TLS since v3.0 and also supports the protocol to be used with forwarders allowing users to consume DNS over TLS public DNS resolver services.[11]

Usage

While many servers support DoT, most client systems do not use it by default.

Linux users can install getdns-utils[12] to use DoT directly with the getdns_query tool or system wide with the stubby daemon.

Windows users can install stubby and tools with an exe or with Chocolatey.
