This project provides a system-wide content filtering utility that controls network traffic by redirecting domain resolution requests to local null addresses. By mapping unwanted hostnames to these addresses at the operating system level, it effectively blocks connections to advertising, tracking, and malicious domains across all applications on a machine. The core of the system is a data-driven build pipeline that aggregates multiple curated source lists into a single, unified configuration file. This process is highly customizable, allowing users to employ declarative filtering logic throug

This project is a comprehensive repository of curated domain blocklists designed for network-wide DNS filtering. It functions as a DNS sinkhole feed, providing the necessary data to intercept and block unwanted network requests at the resolution layer before they reach their destination. By returning null or loopback addresses for identified domains, it prevents connections to malicious infrastructure, advertising servers, and tracking endpoints across all devices on a network. The repository distinguishes itself through a tiered categorization logic that allows users to select protection lev

It also features a filter rule parser that extracts target domains and IP addresses from complex syntaxes while removing comments. The project covers rule aggregation, syntax-awa

Blocky is a stateless DNS proxy that functions as a network-wide ad-blocker and content filter. It operates as a single binary or Docker container with no database or persistent state, accepting DNS queries over UDP, TCP, HTTPS, TLS, QUIC, and HTTP/3 through a unified plugin-based query pipeline. The core of the system is a client-group policy engine that assigns devices to named groups and applies per-group blocklists, allowlists, and upstream resolvers, with all configuration changes applied through hot-reloading without requiring a restart.
