Obtaining, and Installing JWhois Windows Whois Client

JWhois is a program which was created by the GNU for users to perform whois queries on domains in order to determine their ownership, and availability.

The only problem for a long time was that the GNU only distributed jwhois in source code for people using unix operating systems to compile and install themselves.

Fortunantely, a group of people have taken these GNU applications, and ported them over so they may be run on windows.

This tutorial will guide you on the steps needed to obtain this program, and install it, so you may be able to perform whois queries via the command line.

1) Point your browser to (it may be slow)

2) Pick the newest version, and the file which has an .exe extention, at this time, you will want to click on "Download jwhois-3.2.2-2.exe"

3) If you have never downloaded from, you will need to choose a file mirror. This is fairly simple, because it just requires you pick the location that is closest to you. I personally favor the easynews mirror.

4) Begin the download

5) Once the program is downloaded, go through the installation choosing all default options

If you are using Windows XP, you will continue to step 6, if you are using windows 2000 or otherwise, skip to step 7.

6) After the program is installed, click start, right click on the "My Computer" icon, and select properties. Once there, navigate to the "Advanced" Tab and click on the button labeled "Enviroment Variables"

7) After the program is installed, navigate to your desktop, and right click on "my computer" to select properties. Once that window opens, navigate to the advanced tab, and click the button labeled "Enviroment Variables"

8) In the enviroment variables window, click on the variable labeled "Path" in the bottom text box. Once that item is selected, click "Edit"

9) In the "Variable Value" input area, click that option, and hit your "End" key to navigate to the very end. Once there, add a semicolon ( and add "C:\program files\GnuWin32\bin\" to the very end. Once that variable is set, click "ok" in that window, and "ok" in the original my comptuer preferences window

10) Navigate to C:\program files\GnuWin32\bin\ in explorer, and rename jwhois.exe to whois.exe

11) Click start, and select "run", in the run dialog box, type cmd.exe

12) In this new window, attempt to run a whois query by running

it should return the domain registration records for . If it returns an error like

'whois' is not recognized as an internal or external command,
operable program or batch file.
you should run the "path" program to make sure c:\program files\GnuWin32\bin\ is included in your path variable. You may need to reboot in order for that path variable change to take effect.

One thing you should learn about domains is that sometimes results differ from whois server to whois server. To query a domain at a specific whois server run the following command:

One example i had to deal with a couple nights ago was (the domain registrar) showing the correct record, but (the .info domain registry) showing an older record. I had to run

To check the result at the enom whois servers, and

To check the result at .

To check a domain's availability, you will simply run

that would return the following:


Whois Server Version 1.3

Domain names in the .com and .net domains can now be registered
with many different competing registrars. Go to
for detailed information.


>>> Last update of whois database: Wed, 13 Apr 2005 08:24:07 EDT <<<

NOTICE: The expiration date displayed in this record is the date the
registrar's sponsorship of the domain name registration in the registry is
currently set to expire. This date does not necessarily reflect the expiration
date of the domain name registrant's agreement with the sponsoring
registrar.  Users may consult the sponsoring registrar's Whois database to
view the registrar's reported date of expiration for this registration.

TERMS OF USE: You are not authorized to access or query our Whois
database through the use of electronic processes that are high-volume and
automated except as reasonably necessary to register domain names or
modify existing registrations; the Data in VeriSign Global Registry
Services' ("VeriSign") Whois database is provided by VeriSign for
information purposes only, and to assist persons in obtaining information
about or related to a domain name registration record. VeriSign does not

by the following terms of use: You agree that you may use this Data only

operational stability.  VeriSign may restrict or terminate your access to the
Whois database for failure to abide by these terms of use. VeriSign
reserves the right to modify these terms at any time.

The Registry database contains ONLY .COM, .NET, .EDU domains and
If the query returns

that means the domain has yet to be registered at (the whois server which stores records for every domain that has been registered) .

Keep in mind, if you recently registered a domain, it may exist in your registrar's whois database, but not internic's . You should check your registrar's FAQ to see just how long registration takes. some domains may take longer to register than others. for example, .info domains usually register within minutes of initial purchase.

Happy Whoising
