What is Whois Lookup

WHOIS is a query and response protocol that is widely used for fetching values from 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, but is also used for a wider range of other information. You can find the registered, expiry and update date of domain. You can get registrant and registrar information with contact details. You can also find the status of domain, either domain is in lock, unlock or redemption period.
