Unbound DNS resolver Detection

The Unbound DNS resolver is running at this host. Unbound is a validating, recursive, and caching DNS resolver. The Unbound DNS resolver allow remote users to query for version and type information. The query of the CHAOS TXT record 'version.bind', will typically prompt the server to send the information back to the querying source.
Set 'hide-version: yes' in unbound.conf.
