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

NAME
     whois - Internet domain name and network number directory service

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

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

     -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
             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 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.)

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

     -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
             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.

     -6      Use the IPv6 Resource Center (6bone) database.  It contains
             network 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''.

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
     handled 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 obtain information about an
     IPv6 address or hostname using the -6 option, which directs the query to
     6bone.

           whois -6 IPv6-IP-Address
