Using WhoisThisDomain

This utility doesn't require any installation process or additional DLLs. Just put the executable file (WhoisTD.exe) anywhere you like, and run it.
When running WhoisThisDomain utility, the "Choose Domains" window appears. You can type a single domain, or multiple domains separated by commas, space characters, or enter characters. After pressing the 'OK' button, WhoisThisDomain start to retrieve the domain registration records for the domains that you typed.

Creating whois-servers.txt

Starting from version 1.20, you can create your own WHOIS servers list to override the default servers defined by WhoisThisDomain.
In order to use this feature, follow the instructions below:
  1. Create a file named 'whois-servers.txt' in the same folder of WhoisTD.exe
  2. Add the needed servers to the list. Each line should contain the domain extension, a space character, and then the whois server address. For example:
    gov whois.nic.gov
    com rs.internic.net 
    il whois.isoc.org.il
    ir whois.nic.ir
    
  3. In the next time that you run WhoisThisDomain, the specified servers will be used instead of the default servers list stored in WhoisThisDomain.
Be aware that WhoisThisDomain only supports WHOIS servers in port 43. It doesn't support Web-based WHOIS requests.

Build Domains List Option

If you want to check multiple domain names in combinations with multiple domain extensions, this feature can help you. For example, if you want to check abcde, poiuyt, lkjhgf names with .com, .org, .net, .biz extensions, simply type the names list in the first text-box, and the extensions list in the second one. After you click OK, you'll get the list of all possible combinations (abcde.com, abcde.org, abcde.net, and so on...)

Command-Line Options

/domainsfile <Filename> Load all domains in the specified text file and start to get the WHOIS information for them without pressing any button or key. The text file can be in Ascii, Unicode, or UTF8 (with byte order mark)

For example:
WhoisTD.exe /domainsfile "c:\temp\domainslist.txt"

/domainslist <Domains List> Load the specified domains and start to get the WHOIS information for them without pressing any button or key.

For example:
WhoisTD.exe /domainslist "yahoo.com google.com youtube.com"

Translating WhoisThisDomain to other languages

WhoisThisDomain allows you to easily translate all menus, dialog-boxes, and other strings to other languages.
In order to do that, follow the instructions below:
  1. Run WhoisThisDomain with /savelangfile parameter:
    WhoisTD.exe /savelangfile
    A file named WhoisTD_lng.ini will be created in the folder of WhoisThisDomain utility.
  2. Open the created language file in Notepad or in any other text editor.
  3. Translate all menus, dialog-boxes, and string entries to the desired language. Optionally, you can also add your name and/or a link to your Web site. (TranslatorName and TranslatorURL values) If you add this information, it'll be used in the 'About' window.
  4. After you finish the translation, Run WhoisThisDomain, and all translated strings will be loaded from the language file.
    If you want to run WhoisThisDomain without the translation, simply rename the language file, or move it to another folder.
