WhoIs information refers to the data recorded for a specific domain. Whenever you register a domain, you’re required to provide certain personal details.

However, most of the time, you have the option to keep this personal information private and not share it publicly.

Additionally, WhoIs databases store other crucial details about a domain, including its registration date, expiration date, and the registrar’s information.

This information is particularly useful if you’re interested in purchasing a domain that’s already owned by someone else, as it allows you to find out when the domain might become available again.

At the very least, a WhoIs lookup will reveal the domain’s registration and expiration dates, along with the registrar’s details, providing a snapshot of the domain’s current status and ownership.
