unwind — validating DNS resolver
unwind is a validating DNS resolver. It is intended to run on client
machines like workstations or laptops and only listens on localhost.
unwind sends DNS queries to nameservers to answer queries and
switches to resolvers learned from dhclient(8) if it detects that
DNS queries are blocked by the local network. It periodically probes
if DNS is no longer blocked and switches back to querying nameservers
itself.
unwind is usually started at boot time, and can be enabled by
using the tool rcctl:
# rcctl enable unwind
