Unbound is a validating, recursive, and caching DNS resolver that provides high performance and security. This free software, licensed under BSD, adheres to open standards and focuses on user privacy. It supports DNS-over-TLS and DNS-over-HTTPS, allowing for encrypted communications, as well as features like Query Name Minimisation and Aggressive Use of DNSSEC-Validated Cache, which reduce data exposure and enhance the robustness of DNS.
It is the ideal software for system administrators and companies looking for a reliable solution. Its modular architecture incorporates DNSSEC validation, IPv6 support, and a resolution library for clients. It is part of the base system of FreeBSD and OpenBSD, being a modern alternative to BIND.
The configuration is flexible, with detailed options in man pages, and the software is optimized for low resource usage, making it ideal for large installations. NLnet Labs maintains Unbound with regular updates, prioritizing security and community feedback.
