BetterWhois, named after the original whois, lets you look up registration information from all Internet domain name registrars at the same time. BetterWhois is located at the BetterWhois.com Web site.
In the past, the whois facility has provided the way for anyone to find out whether a domain name had been taken and, if so, the name of the company who had reserved or paid for it. whois is maintained by Network Solutions, the original .com, .org, and .net registrar on the Internet. Network Solutions has a contract with the U.S. Commerce Department and, until recently, has been the sole registrar in these domains. Recently, however, the newly-formed Internet Corporation for Assigned Names and Numbers (ICANN) has opened the service of domain name registration in these domains to other companies. While Network Solutions continues to be the largest registrar, at least six new companies are now offering similar services, and scores of companies are expected to be offering registration services in the near future.
BetterWhois lets you search the registration databases of all the accredited registrars in a single search. They also provide a linked list of all the registrars and allow a user to receive the detailed domain report by e-mail.
