knot-host 2.6.4-1 (arm64 binary) in ubuntu bionic

 Knot DNS is a fast, authoritative only, high performance, feature
 full and open source name server.
 .
 Knot DNS is developed by CZ.NIC Labs, the R&D department of .CZ
 registry and hence is well suited to run anything from the root
 zone, the top-level domain, to many smaller standard domain names.
 .
 This package provides the 'host' program in the form that is bundled
 with the Knot DNS. The 'host' command is designed to be 1:1
 compatible with BIND 9.x 'host' program.
