Unbound
Unbound is a validating, recursive, and caching DNS resolver designed for speed and security.
About Unbound
Unbound is a recursive DNS resolver built by NLnet Labs. It handles DNS queries from clients, walks the domain name system tree to find answers, and caches results for fast lookups. It supports DNSSEC validation out of the box, so you can trust the responses it returns. Unlike stub resolvers, Unbound does the full resolution work itself.
It runs on Linux, BSD, macOS, and Windows. You can configure access control lists, set up forwarding zones, and tune cache sizes. It works well as a local resolver for a single machine or as a network-wide server. Unbound also supports DNS over TLS for encrypted queries, making it a good fit for privacy-conscious setups.
Unbound is open source under a BSD license. It is maintained by NLnet Labs, the same group behind NSD and ldns. Many Linux distributions include it in their package repositories, and it is a popular choice for routers, firewalls, and self-hosted DNS servers that need reliable recursive resolution without bloat.
