44.Sh DESCRIPTION
45The
46.Nm
47utility looks up records in the databases maintained by several
48Network Information Centers
49.Pq Tn NICs .
50.Pp
51By default
52.Nm
53starts by querying the Internet Assigned Numbers Authority (IANA) whois server,
54and follows referrals to whois servers
55that have more specific details about the query
56.Ar name .
57The IANA whois server knows about
58IP address and AS numbers
59as well as domain names.
60.Pp
61There are a few special cases where referrals do not work, so
62.Nm
63goes directly to the appropriate server.
64These include point-of-contact handles for ARIN,
65.Pa nic.at ,
66NORID, and RIPE,
67and domain names under
68.Pa ac.uk .
69.Pp
70The options are as follows:
71.Bl -tag -width indent
72.It Fl a
73Use the American Registry for Internet Numbers
74.Pq Tn ARIN
75database.
76It contains network numbers used in those parts of the world covered neither by
77.Tn APNIC , AfriNIC , LACNIC ,
78nor by
79.Tn RIPE .
80The query syntax is documented at
81.Pa https://www.arin.net/resources/whoisrws/whois_api.html#nicname
82.It Fl A
83Use the Asia/Pacific Network Information Center
84.Pq Tn APNIC
85database.
86It contains network numbers used in East Asia, Australia,
87New Zealand, and the Pacific islands.
88Get query syntax documentation using
89.Ic whois -A help
90.It Fl b
91Use the Network Abuse Clearinghouse database.
92It contains addresses to which network abuse should be reported,
93indexed by domain name.
94.It Fl c Ar TLD
95This is the equivalent of using the
96.Fl h
97option with an argument of
98.Qq Ar TLD Ns Li .whois-servers.net .
99This can be helpful for locating country-class TLD whois servers.
100.It Fl f
101Use the African Network Information Centre
102.Pq Tn AfriNIC
103database.
104It contains network numbers used in Africa and the islands of the
105western Indian Ocean.
106Get query syntax documentation using
107.Ic whois -f help
108.It Fl g
109Use the US non-military federal government database, which contains points of
110contact for subdomains of
111.Pa .GOV .
112.It Fl h Ar host
113Use the specified host instead of the default.
114Either a host name or an IP address may be specified.
115.It Fl i
116Use the traditional Network Information Center (InterNIC)
117.Pq Pa whois.internic.net
118database.
119This now contains only registrations for domain names under
120.Pa .COM ,
121.Pa .NET ,
122.Pa .EDU .
123You can specify the type of object to search for like
124.Ic whois -i ' Ns Ar type Ar name Ns Ic '
125where
126.Ar type
127can be
128.Nm domain , nameserver , registrar .
129The
130.Ar name
131can contain
132.Li *
133wildcards.
134.It Fl I
135Use the Internet Assigned Numbers Authority
136.Pq Tn IANA
137database.
138.It Fl k
139Use the National Internet Development Agency of Korea's
140.Pq Tn KRNIC
141database.
142It contains network numbers and domain contact information
143for Korea.
144.It Fl l
145Use the Latin American and Caribbean IP address Regional Registry
146.Pq Tn LACNIC
147database.
148It contains network numbers used in much of Latin America and the
149Caribbean.
150.It Fl m
151Use the Route Arbiter Database
152.Pq Tn RADB
153database.
154It contains route policy specifications for a large
155number of operators' networks.
156.It Fl p Ar port
157Connect to the whois server on
158.Ar port .
159If this option is not specified,
160.Nm
161defaults to port 43.
162.It Fl P
163Use the PeeringDB database of AS numbers.
164It contains details about presence at internet peering points
165for many network operators.
166.It Fl Q
167Do a quick lookup;
168.Nm
169will not attempt to follow referrals to other whois servers.
170This is the default if a server is explicitly specified
171using one of the other options or in an environment variable.
172See also the
173.Fl R
174option.
175.It Fl r
176Use the R\(aaeseaux IP Europ\(aaeens
177.Pq Tn RIPE
178database.
179It contains network numbers and domain contact information
180for Europe.
181Get query syntax documentation using
182.Ic whois -r help
183.It Fl R
184Do a recursive lookup;
185.Nm
186will attempt to follow referrals to other whois servers.
187This is the default if no server is explicitly specified.
188See also the
189.Fl Q
190option.
191.It Fl S
192By default
193.Nm
194adjusts simple queries (without spaces) to produce more useful output
195from certain whois servers,
196and it suppresses some uninformative output.
197With the
198.Fl S
199option,
200.Nm
201sends the query and prints the output verbatim.
202.El
203.Pp
204The operands specified to
205.Nm
206are treated independently and may be used
207as queries on different whois servers.
208.Sh ENVIRONMENT
209.Bl -tag -width WHOIS_SERVER
210.It Ev WHOIS_SERVER
211The primary default whois server.
212If this is unset,
213.Nm
214uses the
215.Ev RA_SERVER
216environment variable.
217.It Ev RA_SERVER
218The secondary default whois server.
219If this is unset,
220.Nm
221will use

226.Sh EXAMPLES
227To obtain contact information about an
228administrator located in the Russian
229.Tn TLD
230domain
231.Qq Li RU ,
232use the
233.Fl c
234option as shown in the following example, where
235.Ar CONTACT-ID
236is substituted with the actual contact identifier.
237.Pp
238.Dl Ic whois -c RU CONTACT-ID
239.Pp
240(Note: This example is specific to the
241.Tn TLD
242.Qq Li RU ,
243but other
244.Tn TLDs
245can be queried by using a similar syntax.)
246.Pp
247The following example demonstrates how to query
248a whois server using a non-standard port, where
249.Dq Li query-data
250is the query to be sent to
251.Dq Li whois.example.com
252on port
253.Dq Li rwhois
254(written numerically as 4321).
255.Pp
256.Dl Ic whois -h whois.example.com -p rwhois query-data
257.Pp
258Some whois servers support complex queries
259with dash-letter options.
260You can use the
261.Fl -
262option to separate
263.Nm
264command options from whois server query options.
265A query containing spaces must be quoted as one
266argument to the
267.Nm
268command.
269The following example asks the RIPE whois server
270to return a brief description of its
271.Dq Li domain
272object type:
273.Pp
274.Dl Ic whois -r -- '-t domain'
