.Sh NAME
.Nm whois
.Nd "Internet domain name and network number directory service"
.Sh SYNOPSIS
.Nm
.Op Fl aAbfgiIklmQrR
.Op Fl c Ar country-code | Fl h Ar host
.Op Fl p Ar port
.Ar name ...
.Sh DESCRIPTION
The
.Nm
utility looks up records in the databases maintained by several
Network Information Centers
.Pq Tn NICs .
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl a
Use the American Registry for Internet Numbers
.Pq Tn ARIN
database.
It contains network numbers used in those parts of the world covered neither by
.Tn APNIC , AfriNIC , LACNIC ,
nor by
.Tn RIPE .
.Pp
(Hint: All point of contact handles in the
.Tn ARIN
whois database end with
.Qq Li -ARIN . )
.Pp
.It Fl A
Use the Asia/Pacific Network Information Center
.Pq Tn APNIC
database.
It contains network numbers used in East Asia, Australia,
New Zealand, and the Pacific islands.
.It Fl b
Use the Network Abuse Clearinghouse database.
It contains addresses to which network abuse should be reported,
indexed by domain name.
.It Fl c Ar country-code
This is the equivalent of using the
.Fl h
option with an argument of
.Qq Ar country-code Ns Li .whois-servers.net .
.It Fl f
Use the African Network Information Centre
.Pq Tn AfriNIC
database.
It contains network numbers used in Africa and the islands of the
western Indian Ocean.
.It Fl g
Use the US non-military federal government database, which contains points of
contact for subdomains of
.Pa .GOV .
.It Fl h Ar host
Use the specified host instead of the default variant.
Either a host name or an IP address may be specified.
.Pp
By default
.Nm
constructs the name of a whois server to use from the top-level domain
.Pq Tn TLD
of the supplied (single) argument, and appending
.Qq Li .whois-servers.net .
This effectively allows a suitable whois server to be selected
automatically for a large number of
.Tn TLDs .
.Pp
In the event that an IP
address is specified, the whois server will default to the American
Registry for Internet Numbers
.Pq Tn ARIN .
If a query to
.Tn ARIN
references
.Tn APNIC , AfriNIC , LACNIC ,
or
.Tn RIPE ,
that server will be queried also, provided that the
.Fl Q
option is not specified.
.Pp
If the query is not a domain name or IP address,
.Nm
will fall back to
.Pa whois.crsnic.net .
.It Fl i
Use the Network Solutions Registry for Internet Numbers
.Pq Pa whois.networksolutions.com
database.
It contains network numbers and domain contact information for most of
.Pa .COM , .NET , .ORG
and
.Pa .EDU
domains.
.Pp
.Sy 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
.Tn InterNIC
database
.Pq Pa whois.internic.net
is no longer handled by Network Solutions, Inc.
For details, see
.Pa http://www.internic.net/ .
.Pp
(Hint: Contact information, identified by the term
.Em handle ,
can be looked up by prefixing
.Qq Li "handle "
to the
.Tn NIC
handle in the query.)
.It Fl I
Use the Internet Assigned Numbers Authority
.Pq Tn IANA
database.
It contains network information for top-level domains.
.It Fl k
Use the National Internet Development Agency of Korea's
.Pq Tn KRNIC
database.
It contains network numbers and domain contact information
for Korea.
.It Fl l
Use the Latin American and Caribbean IP address Regional Registry
.Pq Tn LACNIC
database.
It contains network numbers used in much of Latin America and the
Caribbean.
.It Fl m
Use the Route Arbiter Database
.Pq Tn RADB
database.
It contains route policy specifications for a large
number of operators' networks.
.It Fl p Ar port
Connect to the whois server on
.Ar port .
If this option is not specified,
.Nm
defaults to port 43.
.It Fl Q
Do a quick lookup.
This means that
.Nm
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.
.It Fl r
Use the R\(aaeseaux IP Europ\(aaeens
.Pq Tn RIPE
database.
It contains network numbers and domain contact information
for Europe.
.It Fl R
Use the Russia Network Information Center
.Pq Tn RIPN
database.
It contains network numbers and domain contact information
for subdomains of
.Pa .RU .
This option is deprecated; use the
.Fl c
option with an argument of
.Qq Li RU
instead.
.El
.Pp
The operands specified to
.Nm
are treated independently and may be used
as queries on different whois servers.
.Sh EXIT STATUS
.Ex -std
.Sh EXAMPLES
Most types of data, such as domain names and
.Tn IP
addresses, can be used as arguments to
.Nm
without any options, and
.Nm
will choose the correct whois server to query.
Some exceptions, where
.Nm
will not be able to handle data correctly, are detailed below.
.Pp
To obtain contact information about an
administrator located in the Russian
.Tn TLD
domain
.Qq Li RU ,
use the
.Fl c
option as shown in the following example, where
.Ar CONTACT-ID
is substituted with the actual contact identifier.
.Pp
.Dl "whois -c RU CONTACT-ID"
.Pp
(Note: This example is specific to the
.Tn TLD
.Qq Li RU ,
but other
.Tn TLDs
can be queried by using a similar syntax.)
.Pp
The following example demonstrates how to query
a whois server using a non-standard port, where
.Dq Li query-data
is the query to be sent to
.Dq Li whois.example.com
on port
.Dq Li rwhois
(written numerically as 4321).
.Pp
.Dl "whois -h whois.example.com -p rwhois query-data"
