WHOIS Domain Lookup allows you to query a certain domain name and to view its associated details. This can be very helpful when you're looking to register a domain.
To find WHOIS information for a specific domain name, type the domain name in the search box and select the TLD from the drop down menu.

Please note that there are restrictions in place on how many queries you can make per day from the same IP address. If you exceed the limit your access can be blocked.
