|
||||
.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 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 covered neither by
|
||||
.Tn APNIC
|
||||
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 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 d
|
||||
Use the US Department of Defense
|
||||
database.
|
||||
It contains points of contact for subdomains of
|
||||
.Pa .MIL .
|
||||
.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 , 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 Internet Assigned Numbers Authority
|
||||
.Pq Tn IANA
|
||||
database.
|
||||
It contains network information for top-level domains.
|
||||
.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.
|
||||
This database holds no information on 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 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 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.
|
||||
.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 operands specified to
|
||||
.Nm
|
||||
are treated independently and may be used
|
||||
as queries on different whois servers.
|
||||
.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).
|
||||
.Pp
|
||||
.Dl "whois -h whois.example.com -p rwhois query-data"
