Description:
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.
