Android 13 will support “DNS over HTTPS” (DoH)

Google will add native support for “DNS over HTTPS” on Android 13 (as well as for UWB technology), making all web traffic even more secure and respectful of privacy.

On the surface, web browsing seems like a fairly straightforward process for the average user – just type a URL into the address bar, hit enter, and the browser loads the corresponding website. However, what happens behind the scenes is obviously more complicated.

After pressing Enter, the device queries a Domain Name Server (DNS) to translate the URL into a machine-readable IP address. Once the device receives the corresponding IP address, it opens the website. This communication between the computer (or smartphone) and the DNS takes place in clear text via the User Data Protocol (UDP) or Transmission Control Protocol (TCP) standards and is visible to anyone who can see the connection. If you don’t want anyone to have access to this data, you need to use a DNS that supports a private standard such as DNS-over-TLS (DoT) or DNS-over-HTTPS (DoH).

Many popular DNS servers, such as Google Public DNS, NextDNS, and Cloudflare, support both DoT and DoH standards. However, currently Android only supports DoT natively. Google has added native support for DoT, aptly named Private DNS, in Android 9 Pie and it can be found in the Advanced section of the network and Internet settings of smartphones.

But if you want to configure these settings to use “DNS over HTTPS”, you’ll have to wait for Google to launch Android 13 “Tiramisu” next year.

A recent code modification of the Android Open Source Project (AOSP) suggests that Google will add DoH support in Android 13. Its description states: “Enable the default DoH function in T“. Since Google internally refers to Android 13 as T or “Tiramisu”, we expect the company to add native DoH support in the “Private DNS” menu in Android next year.

While DoT and DoH essentially do the same thing, DoT uses TLS (also known as SSL) to encrypt DNS traffic, which is the same protocol used by HTTPS websites to encrypt and authenticate communications. DoH, on the other hand, uses HTTP or HTTP / 2 protocols to send queries and responses rather than directly over UDP. Both standards also use different ports, which gives DoH a slight edge from a privacy standpoint.
