WHOIS, also known as "who is", is the name for an Internet function that allows you to search remote WHOIS databases for domain registration information. By performing a simple WHOIS search you can discover when a domain was registered, who registered it, contact information, and more. A WHOIS search can also reveal the name or network mapped to a numerical IP address. Originally, WHOIS searches were performed in a command line environment and took the form, [drive]:\>whois domain.com. Searches can still be performed from the command line, but now you can simply visit a WHOIS website and enter the IP address or domain name.
