DNS Proxy is a lightweight command-line utility developed by AdGuard that acts as a local intermediary between client applications and upstream DNS resolvers, translating standard DNS queries into modern encrypted protocols. Designed for privacy-conscious users, network administrators, and developers, the tool forwards requests over DNS-over-HTTPS (DoH), DNS-over-TLS (DoT), DNS-over-QUIC (DoQ), or DNSCrypt, preventing on-path eavesdropping and manipulation of domain resolution data. Typical deployments include securing home routers, isolating corporate BYOD traffic, anonymizing developer containers, or augmenting existing filtering solutions without altering end-device settings. The program reads a YAML configuration file that lists upstreams, fallback servers, caching parameters, and filtering rules, then exposes a conventional UDP/TCP port 53 listener on localhost or any specified interface; clients continue to use standard DNS while the proxy transparently upgrades transport security. Since its first public build the project has progressed through forty-seven incremental releases, arriving at version 0.81.0, each refining protocol support, performance, and cross-platform compatibility. Written in Go, the single self-contained binary runs on Windows, macOS, Linux, and BSD, ships without GUI components, and integrates easily with systemd, Docker, or Windows Task Scheduler. Users can compile custom builds for embedded architectures or fetch pre-signed checksums for verification. The open-source codebase encourages community contributions, issue tracking, and transparency audits, aligning the utility with broader AdGuard privacy initiatives. DNS Proxy is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
