DNSNet
Block hosts through DNS on Android with DNSNet, a DNS-based filtering app.

About DNSNet
DNSNet is an open-source Android app that blocks unwanted hosts via DNS filtering. It is a continuation of the DNS66 project built with modern Android development practices, and its default configuration uses widely-respected host files to block ads, malware, and other unwanted content. The app operates entirely on-device by leveraging Android's VPN service API to intercept and filter DNS requests without routing traffic to a remote server.
Notable limitations include ongoing battery usage from the constantly running background service, incompatibility with other concurrent VPN services on Android, and broken Windows build support due to issues with the HTTP/3 quiche crate.
