WHOIS(1)		FreeBSD	General	Commands Manual		      WHOIS(1)

     whois -- Internet domain name and network number directory	service

     whois [-adgimpQrR6] [-c country-code | -h host] name ...

     whois looks up records in the databases maintained	by several Network
     Information Centers (NICs).

     The options are as	follows:

     -a	     Use the American Registry for Internet Numbers (ARIN) database.
	     It	contains network numbers used in those parts of	the world cov-
	     ered neither by APNIC nor by RIPE.

	     (Hint: All	point of contact handles in the	ARIN whois database
	     end with "-ARIN".)

     -c	country-code
	     This is the equivalent of using the -h option with	an argument of

     -d	     Use the US	Department of Defense database.	 It contains points of
	     contact for subdomains of .MIL.

     -g	     Use the US	non-military federal government	database, which	con-
	     tains points of contact for subdomains of .GOV.

     -h	host
	     Use the specified host instead of the default variant.  Either a
	     host name or an IP	address	may be specified.

	     By	default	whois constructs the name of a whois server to use
	     from the top-level	domain (TLD) of	the supplied (single) argu-
	     ment, and appending "".	This effectively
	     allows a suitable whois server to be selected automatically for a
	     large number of TLDs.

	     In	the event that an IP address is	specified, the whois server
	     will default to the American Registry for Internet	Numbers
	     (ARIN).  If a query to ARIN references APNIC or RIPE, that	server
	     will be queried also, provided that the -Q	option is not speci-

	     If	the query is not a domain name or IP address, whois will fall
	     back to

     -i	     Use the Network Solutions Registry	for Internet Numbers
	     ( database.  It	contains network num-
	     bers and domain contact information for most of .COM, .NET, .ORG
	     and .EDU domains.

	     NOTE!  The	registration of	these domains is now done by a number
	     of	independent and	competing registrars and this database holds
	     no	information on the domains registered by organizations other
	     than Network Solutions, Inc.  Also, note that the InterNIC	data-
	     base ( is no longer handled by Network Solu-
	     tions, Inc.  For details, see

	     (Hint: Contact information, identified by the term	handle,	can be
	     looked up by prefixing "handle " to the NIC handle	in the query.)

     -m	     Use the Route Arbiter Database (RADB) database.  It contains
	     route policy specifications for a large number of operators' net-

     -p	     Use the Asia/Pacific Network Information Center (APNIC) database.
	     It	contains network numbers used in East Asia, Australia, New
	     Zealand, and the Pacific islands.

     -Q	     Do	a quick	lookup.	 This means that whois will not	attempt	to
	     lookup the	name in	the authoritative whois	server (if one is
	     listed) nor will it contact InterNic if a lookup fails.  This
	     flag has no effect	when combined with any other flag.

     -r	     Use the R'eseaux IP Europ'eens (RIPE) database.  It contains net-
	     work numbers and domain contact information for Europe.

     -R	     Use the Russia Network Information	Center (RIPN) database.	 It
	     contains network numbers and domain contact information for sub-
	     domains of	.RU.

     -6	     Use the IPv6 Resource Center (6bone) database.  It	contains net-
	     work names	and addresses for the IPv6 network.

     The operands specified to whois are concatenated together (separated by
     white-space) and presented	to the whois server.

     The default action, unless	directed otherwise with	a special name,	is to
     do	a very broad search, looking for matches to name in all	types of
     records and most fields (name, nicknames, hostname, net address, etc.) in
     the database.  For	more information as to what name operands have special
     meaning, and how to guide the search, use the special name	``help''.

     Most types	of data, such as domain	names and IP addresses,	can be used as
     arguments to whois	without	any options, and whois will choose the correct
     whois server to query.  Some exceptions, where whois will not be able to
     handled data correctly, are detailed below.

     To	obtain contact information about an administrator located in the Rus-
     sian TLD domain "RU", use the -c option as	shown in the following exam-
     ple, where	CONTACT-ID is substituted with the actual contact identifier.

	   whois -c RU CONTACT-ID

     (Note: This example is specific to	the TLD	"RU", but other	TLDs can be
     queried by	using a	similar	syntax.)

     The following example demonstrates	how to obtain information about	an
     IPv6 address or hostname using the	-6 option, which directs the query to

	   whois -6 IPv6-IP-Address

     Ken Harrenstien and Vic White, NICNAME/WHOIS, 1 March 1982, RFC 812.

     The whois command appeared	in 4.3BSD.
