Unbound is a validating, recursive, caching DNS resolver that focuses on speed, efficiency, and security. Built on open standards, it offers modern features to enhance both privacy and DNS performance. One of its standout capabilities is support for encrypted DNS queries via DNS-over-TLS and DNS-over-HTTPS, which helps protect users’ online privacy by encrypting communication between clients and resolvers.
Privacy improvements also come from techniques like query name minimization and the aggressive use of DNSSEC-validated cache, reducing unnecessary data exchange and strengthening trust in DNS answers. Unbound can even load a copy of the root zone, improving robustness and reliability.
This software runs smoothly on Linux, BSD, and macOS and is often included by default or available in standard repositories. Installation is straightforward, with minimal configuration required to get your network up and running.
As free and open-source software under the BSD license, Unbound is continuously refined with security and privacy as top priorities, guided by user feedback and community standards.
