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 and ::1, and NXDOMAIN for zones served by
AS112. Stub and forward zones are supported.
This package contains the unbound daemon.
