Best SEO Tools offer an easy-to-use Domain Whois Retriever. Simply enter the URL that you wish to check into the search box, press "Continue" and you'll quickly receive the domain name details.

There is much information surrounding a domain name, including the registration information and trademark information. Also, this Domain Whois Retriever allows the user to research which domain names are available and which domain names were previously, recently used but that have now become available.

The Internet Corporation for Assigned Names and Numbers (ICANN) catalogs the personal information of all registrants to the Whois database. The Domain Whois Retriever taps into that information, delivering it back to whoever is searching that specific domain name. Any listing on the ICANN directory is public knowledge and searchable by practically anyone.

There are many reasons to search the Whois database. You may want to know if a domain name that you've had your eye on will be expiring any time soon so you can plan to grab it once it's available. A registrar may want to check out the particulars of a domain name if they're transferring ownership. Also, domain name information can even help out the authorities in criminal cases.

It's important to understand that there are businesses out there that protect people's privacy by substituting the business information for personal information. This means that when you're looking up information about a domain name, you may actually get a business' information instead of the actual owner of the domain name.
