+khost – Simple DNS lookup utility
+=================================
+
+Synopsis
+--------
+
+:program:`khost` [*options*] *name* [*server*]
+
+Description
+-----------
+
+This utility sends a DNS query for the *name* to the *server* and prints a reply
+in more user-readable form. For more advanced DNS queries use :doc:`kdig<man_kdig>`
+instead.
+
+Parameters
+..........
+
+*name*
+ Is a domain name that is to be looked up. If the *name* is IPv4 or IPv6
+ address the PTR query type is used.
+
+*server*
+ Is a name or an address of the nameserver to send a query to. The address
+ can be specified using [address]:port notation. If no server is specified,
+ the servers from :file:`/etc/resolv.conf` are used.
+
+If no arguments are provided, :program:`khost` prints a short help.
+
+Options
+.......
+
+**-4**
+ Use the IPv4 protocol only.
+
+**-6**
+ Use the IPv6 protocol only.
+
+**-a**
+ Send ANY query with verbose mode.
+
+**-d**
+ Enable debug messages.
+
+**-h**, **--help**
+ Print the program help.
+
+**-r**
+ Disable recursion.
+
+**-T**
+ Use the TCP protocol.
+
+**-v**
+ Enable verbose output.
+
+**-V**, **--version**
+ Print the program version.
+
+**-w**
+ Wait forever for the reply.
+
+**-c** *class*
+ Set the query class (e.g. CH, CLASS4). The default class is IN.
+
+**-t** *type*
+ Set the query type (e.g. NS, IXFR=12345, TYPE65535). The default is to send 3
+ queries (A, AAAA and MX).
+
+**-R** *retries*
+ The number (>=0) of UDP retries to query a nameserver. The default is 1.
+
+**-W** *wait*
+ The time to wait for a reply in seconds. This timeout applies to each query
+ try. The default is 2 seconds.
+
+Exit values
+-----------
+
+Exit status of 0 means successful operation. Any other exit status indicates
+an error.
+
+Examples
+--------
+
+1. Get the A, AAAA and MX records for example.com::
+
+ $ khost example.com
+
+2. Get the reverse record for address 192.0.2.1::
+
+ $ khost 192.0.2.1
+
+3. Perform a verbose zone transfer for zone example.com::
+
+ $ khost -t AXFR -v example.com
