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
