My company has been offering a free piece of desktop software, called Whois Web, for a couple of years now. It allows you to lookup the owner of any domain name or IP address from the "comfort of your own desktop" without any advertisements.

It runs on Windows 9x/Me and 2000/XP. You can find out more details or download it from:

Please let me know if have any questions about the program or have any suggestions for improvement.

Best regards,
Frank Rietta
