What will be an ideal response?
The Whois utility is a commonly used tool for gathering IP address and domain information. With just a company's Web address, you can discover a tremendous amount of information. Unfortunately, attackers can also make use of this information. Often companies don't realize that they're publishing information on the Web that computer criminals can use. The Whois utility gives you information on a company's IP addresses and any other domains the company might be part of.
