'host' is a utility, similar to 'nslookup' (deprecated) or 'dig',
used to query DNS servers for domain names and zones.

This package provides the traditional version of 'host', as
delivered with the BSD operating systems. BIND9 provides a
similar utility, in 'bind9-host'. The 'host' package also
provides an implementation of this utility. This 'mirhost'
implementation uses the traditional output format expected
by many shell scripts but lacks some more modern functions,
such as "host 2001:db8::1" (although the form "host -t ptr
1.0.0...8.b.d.1.0.0.2.ip6.arpa." is supported).
