Code by Kevin has released version 4.0 of QuickWho (http://www.codebykevin.com/quickwho.html), a Mac OS X application to help users look up Internet domain registrations. The new version boasts improvement in domain accuracy and a new, under-the-hood application structure for better compliance with Mac App Store guidelines.
QuickWho provides an array of information about specific Internet domains. Are you curious about who owns a particular domain name? Do you want to contact them, or gather more information about them? QuickWho can help you with these tasks.
QuickWho is shareware. The download is a 30-day demo; you can purchase a license to use the program past the 30-day trial period. Mac OS X Lion is the minimum supported platform. QuickWho is a universal binary and licenses cost $24.99.
