KHOST(1)			   Knot	DNS			      KHOST(1)

NAME
       khost - Simple DNS lookup utility

SYNOPSIS
       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
       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	 /etc/resolv.conf  are
	      used.

       If no arguments are provided, 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  de-
	      fault 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  in-
       dicates 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
