TPWhois is a new GPL component released by TemplatePlazza.com, developed based on J!whois from J!Factory, a Joomla! integration of EP Dev Whois by EP-Dev.com. This component will add ability to search any submitted domain whois status within your website, without forwarding (or linking) result page into any external website.

Features :

• Acts as an ordinary whois script, returning whois information natively on about 200 different extensions with the ability to easily add more.
• Can be acted as a whois script for registrars who plan to pass available domains into a billing system for a customer to order.
  
• All of the configuration can be edited from within backend parameter
