igWhois is an easy to install, easy to use Perl based whois lookup script. igWhois can search all top level domains (TLDs) and second level domains (SLDs) outputting the result in a configurable HTML template. You can easily customize the template to blend in with your site’s look and feel. igWhois comes with a domain wizard that suggests possible alternative domains if the domains requested is already taken. igWhois automatically checks its homepage to see if new whois server has been added to the server list.
