[br][br]When you type in a domain, like google.com, the DNS looks up the IP address so content can be loaded. It's a critical part of modern networking, but Android has never had an option for a global DNS setting. If you wanted to change the server, you would have to do it on a per-network basis, while using a static IP address.[br][br][img src="/storage/emulated/0/Pictures/Screenshots/Screenshot_20190406-110640.png"][br][br]When Google announced Android P, one of the listed additions was a 'Private DNS' screen in the settings, but the company didn't clarify how it worked and the setting didn't seem to work at all in our testing. Google has now made a post on the Android Developers Blog, explaining how it works and why it's important.[br][br]As we suspected, this allows you to change the DNS used across all apps and networks, which previously wasn't possible (without a third-party app using a VPN service, that is). Furthermore, Android P will support DNS over TLS, which encrypts all DNS queries so they can't be read or modified by anyone. Not all[a href="https://arstechnica.com/information-technology/2018/04/how-to-keep-your-isps-nose-out-of-your-browser-history-with-encrypted-dns/"] [/a]DNS providers support that technology, but several popular ones do, like google and cloud flare.[br][br]It's worth noting that some apps perform their own DNS queries, and must be updated to support the feature. Hopefully it will start working in the next Android P Developer Preview, so we can try it out.[br][br][br]Thanks For Reading. |
