WHOIS
WHOIS is a query and response protocol used to retrieve registration information about domain names, IP addresses, and autonomous systems. WHOIS records typically include registrant contact details, registration dates, nameservers, and registrar information. OSINT investigators use WHOIS lookups to identify domain owners, track registration changes over time, and discover connections between websites.
