NAME
whois - client for the whois directory service
SYNOPSIS
whois [ { -h | --host } HOST ] [ { -p | --port } PORT ] [ -abBcdGHKlLmMrRx ]
[ -g SOURCE:FIRST-LAST ] [ -i ATTR[,ATTR]... ] [ -s SOURCE[,SOURCE]... ] [ -T TYPE[,TYPE]... ]
[ --verbose ] OBJECT
whois -q KEYWORD
whois -t TYPE
whois -v TYPE
whois --help
whois --version
DESCRIPTION
whois searches for an object in a RFC 3912 database.
This version of the whois client tries to guess the right server to ask for the specified object.
If no guess can be made it will connect to whois.networksolutions.com for NIC handles or
whois.arin.net for IPv4 addresses and network names.
OPTIONS
-h HOST, --host HOST
Connect to HOST.
-H Do not display the legal disclaimers some registries like to show you.
-p, --port PORT
Connect to PORT.
--verbose
Be verbose.
--help Display online help.
--version
Display client version information.
Other options are flags understood by whois.ripe.net and some other RIPE-like servers:
-a Also search all the mirrored databases.
-b Return brief IP address ranges with abuse contact.
-B Disable object filtering. (Show the e-mail addresses.)
-c Return the smallest IP address range with a reference to an irt object.
-d Return the reverse DNS delegation object too.
-g SOURCE:FIRST-LAST
Search updates from SOURCE database between FIRST and LAST update serial number. It's use‐
ful to obtain Near Real Time Mirroring stream.
-G Disable grouping of associated objects.
-i ATTR[,ATTR]...
Search objects having associated attributes. ATTR is attribute name. Attribute value is
positional OBJECT argument.
-K Return primary key attributes only. Exception is members attribute of set object which is
always returned. Another exceptions are all attributes of objects organisation, person,
and role that are never returned.
-l Return the one level less specific object.
-L Return all levels of less specific objects.
-m Return all one level more specific objects.
-M Return all levels of more specific objects.
-q KEYWORD
Return list of keywords supported by server. KEYWORD can be version for server version,
sources for list of source databases, or types for object types.
-r Disable recursive look-up for contact information.
-R Disable following referrals and force showing the object from the local copy in the
server.
-s SOURCE[,SOURCE]...
Request the server to search for objects mirrored from SOURCES. Sources are delimited by
comma and the order is significant. Use -q sources option to obtain list of valid
sources.
-t TYPE Return the template for a object of TYPE.
-T TYPE[,TYPE]...
Restrict the search to objects of TYPE. Multiple types are separated by a comma.
-v TYPE Return the verbose template for a object of TYPE.
-x Search for only exact match on network address prefix.
NOTES
Please remember that whois.networksolutions.com by default will only search in the domains data‐
base. If you want to search for NIC handles you have to prepend a ! character. When you do this,
the default server becomes whois.networksolutions.com.
When querying whois.arin.net for IPv4 or IPv6 networks, the CIDR netmask length will be automati‐
cally removed from the query string.
When querying whois.nic.ad.jp for AS numbers, the program will automatically convert the request
in the appropriate format, inserting a space after the string AS.
When querying whois.denic.de for domain names and no other flags have been specified, the program
will automatically add the flag -T dn.
When querying whois.dk-hostmaster.dk for domain names and no other flags have been specified, the
program will automatically add the flag --show-handles.
RIPE-specific command line options are ignored when querying non-RIPE servers. This may or may not
be the behaviour intended by the user. When querying a non-standard server, command line options
which are not to be interpreted by the client should always follow the -- separator (which marks
the beginning of the query string).
If the /etc/whois.conf configuration file exists, it will be consulted to find a server before
applying the normal rules. Each line of the file should contain a regular expression to be matched
against the query text and the whois server to use, separated by white space. IDN domains must
use the ACE format.
The whois protocol does not specify an encoding for characters which cannot be represented by
ASCII and implementations vary wildly. If the program knows that a specific server uses a certain
encoding, if needed it will transcode the server output to the encoding specified by the current
system locale.
Command line arguments will always be interpreted accordingly to the current system locale and
converted to the IDN ASCII Compatible Encoding.
FILES
/etc/whois.conf
ENVIRONMENT
LANG When querying whois.nic.ad.jp and whois.jprs.jp English text is requested unless the LANG
or LC_MESSAGES environment variables specify a Japanese locale.
WHOIS_OPTIONS
A list of options which will be evaluated before the ones specified on the command line.
WHOIS_SERVER
This server will be queried if the program cannot guess where some kind of objects are
located. If the variable does not exist then whois.arin.net will be queried.

BUGS
The program may have buffer overflows in the command line parser: be sure to not pass untrusted
data to it. It should be rewritten to use a dynamics strings library.
HISTORY
This program closely tracks the user interface of the whois client developed at RIPE by Ambrose
Magee and others on the base of the original BSD client. I also added support for the protocol
extensions developed by David Kessens of QWest for the 6bone server.
