Whois Domain Lookup

WHOIS (pronounced as the phrase 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 but is also used for a wider range of other information. The protocol stores and delivers database content in a human-readable format. The WHOIS lookup is used to identify the owner of a domain name, their contact information, and when the domain was registered, among other information. The WHOIS system is typically maintained by the organization responsible for allocating Internet resources, such as ICANN for domain names, and various organizations for IP addresses.

You can perform a WHOIS lookup by visiting a domain registrar or a WHOIS service website and entering the domain name you want to look up. Some of the well-known WHOIS services include ICANN, Network Solutions, GoDaddy, Namecheap, etc. These services will often provide more information beyond just the owner's contact details, including the status of the domain name, expiration date, name servers, and more.
