Summary
Perform WHOIS lookups across more than 40 domain extensions.
The Whois® lookup app is essentially a bookmarklet for your home/starting page that will take you on our WHOIS lookups page, where you can do 2 types of WHOIS lookup.
The WHOIS lookup tool is a hosted tool that will first give you the results of a thin query, and then if you need more detail, a thick WHOIS query.
If you don't want a bookmarklet, and would prefer to do single click WHOIS lookups from a page that you are visiting, take a look at our WHOIS lookup extension for Chrome.
