About Unbound
Unbound is a validating, recursive, and caching DNS 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.
The source code is under
a BSD License.
