I used it to hide my DNS from statist spies. With DNScrypt as SimpleDNScrypt. It did work, but often broke down. I had to waste extra time to fix it by restarting the unbound service. Today I got fed up with it and switched to the Acrylic DNS proxy. So far it's been working fine. Unbound will no longer break on me.

What is 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.
