Prints information about specified hosts or zones in DNS. Hosts may be IP addresses or hostnames; host converts IP addresses to hostnames by default and appends the local domain to hosts without a trailing dot. Default servers are determined in /etc/resolv.conf. For more information about hosts and zones, refer to Chapters 1 and 2 of DNS and BIND (O'Reilly).

Search for specified resource record class (in[ternet], cs[net], ch[aos], hs/hesiod, or any). Default is in. The chaos and csnet classes, although defined in RFC1035, are rejected as invalid classes by the host command.

Verbose. Include all fields from the resource record, even time-to-live and class, as well as "additional information" and "authoritative nameservers" (provided by the remote nameserver).
Wait forever for a response from a queried server.
