 libunbound performs and validates DNS lookups; it can be used to convert
 hostnames to IP addresses and back and obtain other information from the
 DNS. Cryptographic validation of results is performed with DNSSEC.

unbound: validating, recursive, caching DNS resolver

 Unbound is a recursive-only caching DNS server which can perform DNSSEC
 validation of results. It implements only a minimal amount of authoritative
 service to prevent leakage to the root nameservers: forward lookups for
 localhost, reverse for 127.0.0.1 and ::1, and NXDOMAIN for zones served by
 AS112. Stub and forward zones are supported.
 .
 This package contains the unbound daemon.

unbound-anchor: utility to securely fetch the root DNS trust anchor

 unbound-anchor is a utility which securely fetches or updates the root DNS
 zone trust anchor. A copy of the current root anchor and root update
 certificate is embedded in unbound-anchor. RFC 5011 trust anchor tracking is
 performed, with fallback to an SSL fetch if this fails.

unbound-host: reimplementation of the 'host' command

 This package provides the 'unbound-host' program that is bundled with the
 Unbound domain name server. This version differs from the one provided in the
 package called host, which is from NIKHEF, and bind9-host, which is from ISC,
 and has a similar but different set of features and options.
