WHOIS is a query and response protocol widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name or an IP address block.
When you perform a WHOIS lookup, you can discover details like:
- Registrar details: The company through which the domain was purchased.
- Registration dates: When the domain was registered and when it expires.
- Contact information: Technical and administrative emails (often redacted for privacy).
- Name Servers: The DNS servers handling traffic for the domain.
