.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
program is a client implementation of the WHOIS protocol for querying
|
|
databases and directory services on the Internet.
|
|
Most often, it is used to query the domain name contact and administration
|
|
databases of Internet Domain Name Registrars.
|
|
.Pp
|
|
The WHOIS protocol does not specify very much of the format of
|
|
either the query or the servers' response.
|
|
In essence, the protocol calls for a
|
|
.Tn NETASCII
|
|
word or phrase to be sent on a
|
|
.Tn TCP
|
|
connection to a
|
|
.Tn WHOIS
|
|
server, which then sends some amount of
|
|
.Tn NETASCII
|
|
in response on the same connection,
|
|
closing the connection when it has finished sending.
|
|
Necessarily, both the format and the content of the response will be server-dependent
|
|
.Po
|
|
e.g. what you get back depends on who you ask, and what you ask
|
|
.Pc .
|
|
.Pp
|
|
By default,
|
|
.Nm
|
|
will send the query to
|
|
.Qq whois.internic.net .
|
|
.Pp
|
|
When
|
|
.Nm
|
|
is used to query an Internet domain name registrar's database, the
|
|
.Ar identifier
|
|
can be either a name
|
|
.Po
|
|
e.g.
|
|
.Qq Karrenberg
|
|
.Pc ,
|
|
a
|
|
.Tn NIC-handle
|
|
.Po
|
|
e.g.
|
|
.Qq DK58
|
|
.Pc ,
|
|
an IP network number
|
|
.Po
|
|
e.g.
|
|
.Qq 192.87.45.0/24
|
|
.Pc ,
|
|
or a domain name
|
|
.Po
|
|
e.g.
|
|
.Qq ripe.net
|
|
.Pc .
|
|
.Sh OPTIONS
|
|
.Bl -tag -width indent
|
|
.It Fl h Ar host
|
|
Query a host other than the default.
|
|
.It Fl p Ar port
|
|
Connect to a
|
|
.Tn TCP
|
|
port other than 43 (the default).
|
|
.El
|
|
.Pp
|
|
By default,
|
|
.Nm
|
|
will attempt to connect to a WHOIS server with both IPv6 and IPv4,
|
|
in that order.
|
|
To force one or the other transport:
|
|
.Bl -tag -width indent
|
|
.It Fl 4
|
|
connect with IPv4/TCP only.
|
|
.It Fl 6
|
|
connect with IPv6/TCP only.
|
|
.El
|
|
.Ss RIPE specific extensions
|
|
This version of
|
|
.Nm
|
|
implements protocol extensions compatible with a version of the RIPE
|
|
database WHOIS server that supports classless IP addresses.
|
|
All IP network numbers are considered classless IP network numbers of
|
|
the form prefix/length, like 192.87.45.0/24 for a class C sized network
|
|
number and 128.86.0.0/16 for a class B sized network number.
|
|
Any length can be given.
|
|
If no length is given, the server assumes a host lookup (i.e. length 32).
|
|
.Pp
|
|
By default, the server will return the first less specific network
|
|
number, which can be an exact match if available in the database.
|
|
.Bl -tag -width indent
|
|
.It Fl a
|
|
This causes the server to include information from
|
|
non-RIPE WHOIS databases in the reply.
|
|
Currently these are the public parts of the US NIC and NSFNET databases.
|
|
Please note that the RIPE NCC does not maintain these databases.
|
|
The information is included for for your convenience only.
|
|
.It Fl F
|
|
fast output.
|
|
Force the WHOIS server to not reformat the output.
|
|
This can save time for large objects.
|
|
The output of the RIPE WHOIS server will be in two letter short form.
|
|
This option implies -r.
|
|
.It Fl L
|
|
lookup all less specific networks.
|
|
Has effect only when looking up IP network numbers.
|
|
.It Fl m
|
|
lookup first level more specific networks.
|
|
Has effect only when looking up IP network numbers.
|
|
.It Fl M
|
|
lookup all more specific networks.
|
|
Has effect only when looking up IP network numbers.
|
|
.It Fl r
|
|
non-recursive lookup.
|
|
This will cause the server to not lookup referenced objects.
|
|
.It Fl R
|
|
suppress referrals.
|
|
Forces local copy of a domain object to be shown even if it contains referral.
|
|
.It Fl i Ar attributes
|
|
attributes is a comma separated list of attributes.
|
|
the WHOIS server will return all objects that match the search keys
|
|
in one of these attributes.
|
|
.It Fl s Ar sources
|
|
sources is a comma separated list of database sources.
|
|
The WHOIS server will only search the databases that match the
|
|
specified sources.
|
|
.It Fl S
|
|
requests the server to leave out "syntactic sugar" that may normally
|
|
be inserted in some database objects.
|
|
.It Fl t Ar type
|
|
requests the server to send a template for an object with type "type".
|
|
.It Fl v Ar type
|
|
requests the server to send a verbose template for an object with type "type".
|
|
.It Fl T Ar types
|
|
types is a comma separated list of object types.
|
|
requests the server to only send back objects that match one of the "types".

.Ss Other Useful WHOIS Servers
|
|
Herewith follows an incomplete list of other potentially useful
|
|
WHOIS servers on the Internet.
|
|
.Pp
|
|
For information about IP address allocations,
|
|
the registrars who handle those allocations are:
|
|
.Bl -tag -width indent
|
|
.It whois.arin.net
|
|
American Registry for Internet Numbers.
|
|
.It whois.apnic.net
|
|
Asia-Pacific Network Information Center.
|
|
.It whois.ripe.net
|
|
Reseaux IP Europeens - Network Coordination Center.
|
|
.El
|
|
.Pp
|
|
Internet domain names can now be registered through many different
|
|
competing registrars, many of whom (but probably not all of whom)
|
|
operate WHOIS servers:
|
|
.Bl -tag -width indent
|
|
.It whois.networksolutions.com
|
|
Network Solutions, operators of the InterNIC.
|
|
.It whois.ripe.net
|
|
RIPE domains, assignments, \*[Am] routing info.
|
|
.It whois.ra.net
|
|
Merit/IRR routing info.
|
|
.It whois.geektools.com
|
|
recursing proxies that query internic.net.
|
|
.It whois.fucknsi.com
|
|
a meta-WHOIS server that attempts to query all the registrars.
|
|
.It whois.opensrs.net
|
|
same as above, but also authoritative for OpenSRS domain names.
|
|
.El
|
|
.Sh RIPE VERSION
|

|
|
Most of the extra flags are ONLY supported by the RIPE whois server,
|
|
or copies of the same version of the software.

Usage of these flags may cause errors on other whois servers.
