What is WHOIS (RDAP)?
WHOIS is a query and response protocol used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name. RDAP is the modern version of WHOIS, providing data in a machine-readable JSON format.
Why check WHOIS data?
- Domain Expiry: Check when a domain needs to be renewed.
- Availability: See if a domain is already taken or if it's available for purchase.
- Security: Verify the registrar and nameservers of a specific website.
