Find WHOIS information for a domain name using this online tool. For example, try wikipedia.org or twitter.com to view their WHOIS information.
WHOIS (pronounced as "who is") is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system.
A WHOIS lookup provides information such as the domain registrar, registration date, expiration date, domain status, name servers, and sometimes contact information for the domain owner (though this is often redacted for privacy reasons).
This tool allows you to quickly look up WHOIS information for any domain name, helping you determine domain availability, ownership details, and registration status.
