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] allowing users to set a DNS server phone-wide on both WiFi and mobile connections, an option that was historically only possible on rooted devices. 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] With Android Pie's support for DNS over TLS, some ad blockers now support using the encrypted protocol as a relatively easy way to access their services versus any of the various work-around methods typically used such as VPNs and proxy servers.[12][13][14]

Implementations

Many public recursive servers support DoT, but client systems are often required to opt in.

Android clients use DNS over TLS by default.

Linux and Windows users can use DNS over TLS as a client through the NLNetLabs stubby daemon or Knot Resolver[15]. Alternatively they may install getdns-utils[16] to use DoT directly with the getdns_query tool.

The open source Technitium DNS Server can be used with Windows, Linux, or macOS as a DNS proxy by configuring forwarder option to use DNS over TLS [17].

systemd-resolved is a Linux-only implementation that must be configured to use DNS over TLS, by editing /etc/systemd/resolved.conf and enabling the DNSOverTLS setting.
