AddInternet Domain Search is a free software that allows you to search for domain names available for registration as well as find out who is a domain owner by searching the global Whois database. The software features two main functions for global searches: Domain Search and Whois Search.

Just enter the internet domain name you are looking for and click Go. The software will show you all domains and domain extensions available for registration.
Whois Search: if a domain is already taken this function allows you to find out who is the domain owner including data such as company, name, address, email and more by searching the global Whois domain database. Just enter the domain name you are researching on the Whois Search box and click Go. The software will show you all available data for that domain and is able to do searches on all domain extensions!
