khost(1)		    Knot DNS, version 1.6.6		      khost(1)

NAME
       khost - Simple DNS lookup utility (libknot equivalent of ISC host)

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.

       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 short help.

OPTIONS
       -4  Use IPv4 protocol only.

       -6  Use IPv6 protocol only.

       -a  Send ANY query with verbose mode.

       -d  Enable debug messages if any.

       -h, --help
	   Print help.

       -r  Disable recursion.

       -s  Stop querying next nameserver if SERVFAIL response is received.

       -T  Use TCP protocol.

       -v  Enable verbose output.

       -V, --version
	   Print program version.

       -w  Wait forever for the reply.

       -c class
	   Set query class (e.g. CH, CLASS4). The default class is IN.

       -t type
	   Set 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.

NOTES
   Missing features with regard to ISC host
       Options -C, -i, -l, -m, -N.

   Differences with regard to ISC host
       Option -d is not equivalent to -v, but enables debug messages.

       The number of retries can be set to zero.

       Verbose mode has slightly different format (same as kdig).

EXAMPLES
       Example 1. Get A, AAAA and MX records for example.com:

       # khost example.com

       Example 2. Get reverse record for address 192.0.2.1:

       # khost 192.0.2.1

       Example 3. Perform verbose zone transfer for zone example.com:

       # khost -t AXFR -v example.com

FILES
       /etc/resolv.conf
