According to reports from XDA Developers Forum, Google appears to be planning to add “DNS over TLS” support to Android. The new development will encrypt your domain name server (DNS) requests to massively protect your Web history and make the experience more secure and safe, without the use of any third-party virtual private network (VPN) or proxy.
XDA explains DNS over TLS as a protocol where DNS queries will be encrypted to the same level as HTTPS and thus a DNS can’t actually log or see the websites you visit. This uses TLS, or Transport Layer Security, to achieve this encryption. This does require the DNS you are using to have DNS over TLS support, though, but it’s a start.
Updates to the Android repository suggest you will be able to disable DNS over TLS, and that it may arrive in a future update.
About half of all website traffic is now encrypted, and adding DNS over TLS will work to further improve user privacy. Keep in mind that most DNS does not support this encryption, and changing the mobile DNS on your phone requires either root access or the use of a VPN app.
The new security feature on Android is vital as the smartphone operating system is often a soft target for hackers. It will also make it difficult for ISPs to provide private Web browsing details to governments and private agencies in snooping cases.
