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

NAME
     whois - Internet domain name and network number directory service

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

DESCRIPTION
     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
             covered 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
             "country-code.whois-servers.net".

     -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
             contains 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)
             argument, and appending ".whois-servers.net".  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 whois.crsnic.net.

     -i      Use the Network Solutions Registry for Internet Numbers
             (whois.networksolutions.com) database.  It contains network
             numbers 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
             database (whois.internic.net) is no longer handled by Network
             Solutions, Inc.  For details, see http://www.internic.net/.

             (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
             information 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'
             networks.

     -p port
             Connect to the whois server on port.  If this option is not
             specified, 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
             options.

     -r      Use the R'eseaux IP Europ'eens (RIPE) database.  It contains
             network 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
             subdomains 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.

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

EXAMPLES
     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
     Russian TLD domain "RU", use the -c option as shown in the following
     example, 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
     ``whois.example.com'' on port ``rwhois'' (written numerically as 4321).

           whois -h whois.example.com -p rwhois query-data
