.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 Ds
|
||||||
|
.It Fl 6
|
||||||
|
Use the IPv6 Resource Center
|
||||||
|
.Pq Tn 6bone
|
||||||
|
database.
|
||||||
|
It contains network names and addresses for the IPv6 network.
|
||||||
|
.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 a
|
||||||
|
Use the American Registry for Internet Numbers
|
||||||
|
.Pq Tn ARIN
|
||||||
|
database.
|
||||||
|
It contains network numbers used in those parts of the world
|
||||||
|
not covered by
|
||||||
|
.Tn AfriNIC ,
|
||||||
|
.Tn APNIC ,
|
||||||
|
.Tn LACNIC
|
||||||
|
or by
|
||||||
|
.Tn RIPE .
|
||||||
|
.Pp
|
||||||
|
(Hint: All point of contact handles in the
|
||||||
|
.Tn ARIN
|
||||||
|
whois database end with
|
||||||
|
.Qq Li -ARIN . )
|
||||||
|
.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 d
|
||||||
|
Use the US Department of Defense database.
|
||||||
|
It contains points of contact for subdomains of
|
||||||
|
.Tn \&.MIL .
|
||||||
|
.It Fl f
|
||||||
|
Use the African Network Information Center
|
||||||
|
.Pq Tn AfriNIC
|
||||||
|
database.
|
||||||
|
It contains network numbers used in Africa.
|
||||||
|
.It Fl g
|
||||||
|
Use the US non-military federal government database, which contains points of
|
||||||
|
contact for subdomains of
|
||||||
|
.Tn \&.GOV .
|
||||||
|
.It Fl h Ar host
|
||||||
|
Use the specified host instead of the default NIC
|
||||||
|
(whois.crsnic.net).
|
||||||
|
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 AfriNIC, APNIC , 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 Tn whois.networksolutions.com
|
||||||
|
database.
|
||||||
|
Historically, it contained network numbers and domain contact information
|
||||||
|
for most of
|
||||||
|
.Tn \&.COM ,
|
||||||
|
.Tn \&.NET ,
|
||||||
|
.Tn \&.ORG
|
||||||
|
and
|
||||||
|
.Tn \&.EDU
|
||||||
|
domains.
|
||||||
|
However, 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
|
||||||
|
.Lk http://www.internic.net/ .
|
||||||
|
.Pp
|
||||||
|
(Hint: Contact information, identified by the term
|
||||||
|
.Em handle ,
|
||||||
|
can be looked up by prefixing
|
||||||
|
.Qq Li \&!
|
||||||
|
or
|
||||||
|
.Qq Li handle\ \&
|
||||||
|
to the
|
||||||
|
.Tn NIC
|
||||||
|
handle in the query.)
|
||||||
|
.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 the
|
||||||
|
.Dq whois
|
||||||
|
port listed in
|
||||||
|
.Pa /etc/services
|
||||||
|
(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) nor will it contact InterNic if a lookup
|
||||||
|
fails.
|
||||||
|
This flag has no effect when combined with any other flag.
|
||||||
|
.It Fl R
|
||||||
|
Use the Russia Network Information Center
|
||||||
|
.Pq Tn RIPN
|
||||||
|
database.
|
||||||
|
It contains network numbers and domain contact information
|
||||||
|
for subdomains of
|
||||||
|
.Tn \&.RU .
|
||||||
|
This option is deprecated; use the
|
||||||
|
.Fl c
|
||||||
|
option with an argument of
|
||||||
|
.Qq Li RU
|
||||||
|
instead.
|
||||||
|
.It Fl r
|
||||||
|
Use the R\(aaeseaux IP Europ\(aaeens
|
||||||
|
.Pq Tn RIPE
|
||||||
|
database.
|
||||||
|
It contains network numbers and domain contact information for Europe.
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
The default action, unless directed otherwise with a special
|
||||||
|
.Ar name ,
|
||||||
|
is to do a very broad search, looking for matches to
|
||||||
|
.Ar name
|
||||||
|
in all types of records and most fields (name, nicknames, hostname, net
|
||||||
|
address, etc.) in the database.
|
||||||
|
For more information as to what
|
||||||
|
.Ar name
|
||||||
|
operands have special meaning, and how to guide the search, use
|
||||||
|
the special name
|
||||||
|
.Dq help .
|
||||||
|
.Ss Special cases
|
||||||
|
Queries beginning with an exclamation point
|
||||||
|
.Ql \&!
|
||||||
|
are assumed to be
|
||||||
|
.Tn NSI
|
||||||
|
contact handles.
|
||||||
|
Unless a host or domain is specified on the command line,
|
||||||
|
.Pq Tn whois.networksolutions.com
|
||||||
|
will be used as the
|
||||||
|
.Nm
|
||||||
|
database.
|
||||||
|
.Pp
|
||||||
|
Similarly, queries beginning with
|
||||||
|
.Dq COCO-
|
||||||
|
are assumed to be
|
||||||
|
.Tn CORE
|
||||||
|
contact handles.
|
||||||
|
Unless a host or domain is specified on the command line,
|
||||||
|
.Pq Tn whois.corenic.net
|
||||||
|
will be used as the
|
||||||
|
.Nm
|
||||||
|
database.
|
||||||
|
.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 obtain information about an
|
||||||
|
.Tn IPv6
|
||||||
|
address or hostname using the
|
||||||
|
.Fl 6
|
||||||
|
option, which directs the query to
|
||||||
|
.Tn 6bone .
|
||||||
|
.Pp
|
||||||
|
.Dl "whois -6 IPv6-IP-Address"
|
||||||
|
.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).
