The Whois Tool is a client utility that obtains domain registration information from WHOIS servers worldwide. It supports IP address queries, and automatically selects the correct WHOIS server for IP addresses.
Some background information on what Whois is: it's a protocol for submitting a query to a database to determine the owner of a domain name, IP network or autonomous system number.
But back to Whois Tool. It's a powerful yet incredibly user-friendly resource. It's fully multithreaded and 100% RFC 954 compliant. It's able to perform recursive whois queries and automatically finds whois servers for any top level domain and can query them.
For hosting companies on the lookout for a reliable Whois search, Whois Tool is the perfect fit. With its ability to allow customers to lookup and register available domain names, you'll be able to provide a top-notch service to your clients.
