Based on DNS66, this projects aims to continue the goals of the original app with modern Android development practices.

This is a DNS-based host blocker for Android. In the default configuration, several widely-respected host files are used to block ads, malware, and other weird stuff.

DNSNet allows you to take more control over what internet traffic goes in and out of your device. You can download host files to block a set of known advertising or malicious host names and then create exemptions where you see fit.

It works by creating a lightweight VPN service that filters your internet traffic as you use your device. If you ever have trouble with connecting to a site or using an app, you can always exempt an app from filtering or create an exception for a specific host name.

Using it

There's also no validation of input, so DNS servers that are not valid IPv4 addresses are not rejected, neither are URLs for DNS server entries (we intend to support URLs in the future, so you can point the app to a remote list of servers). How it works

The app establishes a VPN service, with routes for all DNS servers diverted to it. The VPN service then intercepts the packages for the servers and forwards any DNS queries that are not blacklisted.

Custom upstream DNS can be configured. If the feature is turned off, the current connection's DNS servers are used. Privacy Guarantee Privacy is the most important aspect of DNSNet. Currently, DNSNet is strictly data reducing: Running it can only reduce the amount of data leaving your device, not increase it (except for fetching hosts files, obviously), as for each request, we will either allow it to leave your device or not - we will not send other requests or add other information to the request.
