Summary

Unbound is a validating, recursive, and caching DNS(SEC) resolver.

The C implementation of Unbound is developed and maintained by NLnet

Labs. It is based on ideas and algorithms taken from a java prototype

developed by Verisign labs, Nominet, Kirei and ep.net.

Unbound is designed as a set of modular components, so that also

DNSSEC (secure DNS) validation and stub-resolvers (that do not run

as a server, but are linked into an application) are easily possible.
