Validating, recursive, and caching DNS resolver

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.

Goals * A validating recursive DNS resolver. * Code diversity in the DNS resolver monoculture. * Drop-in replacement for BIND apart from config. * DNSSEC support. * Fully RFC compliant. * High performance, even with validation enabled. * Used as stub resolver, full caching name server, resolver library. * Elegant design of validator, resolver, cache modules. o provide the ability to pick and choose modules. * Robust. * In C, open source The BSD license. * Smallest as possible component that does the job. * Stub-zones can be configured local data or AS112 zones.

Non-goals * An authoritative name server. * Too many Features.
