     whois -- Internet domain name and network number directory	service

     whois [-aAbfgiIklmQrR] [-c	country-code | -h host]	[-p port] name ...

     The whois utility 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, AfriNIC, LACNIC, nor by RIPE.

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

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

     -b	     Use the Network Abuse Clearinghouse database.  It contains
	     addresses to which	network	abuse should be	reported, indexed by
	     domain name.

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

     -f	     Use the African Network Information Centre	(AfriNIC) database.
	     It	contains network numbers used in Africa	and the	islands	of the
	     western Indian Ocean.

     -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, AfriNIC, LACNIC, or
	     RIPE, that	server will be queried also, provided that the -Q
	     option is not specified.

	     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.)

     -I	     Use the Internet Assigned Numbers Authority (IANA)	database.  It
	     contains network information for top-level	domains.

     -k	     Use the National Internet Development Agency of Korea's (KRNIC)
	     database.	It contains network numbers and	domain contact infor-
	     mation for	Korea.

     -l	     Use the Latin American and	Caribbean IP address Regional Registry
	     (LACNIC) database.	 It contains network numbers used in much of
	     Latin America and the Caribbean.

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

     -p	port
	     Connect to	the whois server on port.  If this option is not spec-
	     ified, whois defaults to port 43.

     -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).  This option has no effect when combined with any	other

     -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.  This option is deprecated; use the -c option
	     with an argument of "RU" instead.

	     The operands specified to whois are treated independently and may
	     be	used as	queries	on different whois servers.

     The whois utility exits 0 on success, and >0 if an	error occurs.

     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
     handle 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 query a whois server using a
     non-standard port,	where ``query-data'' is	the query to be	sent to
     ``'' on port ``rwhois'' (written numerically as 4321).

	   whois -h -p rwhois	query-data

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

     The whois command appeared	in 4.3BSD.
