WHOIS lookups are a foundational tool for domain research, offering insight into who owns a domain name, when it was registered, when it expires, and which registrar issued it. These records are essential for cybersecurity, brand protection, and investigating suspicious websites. In this article, we’ll explore what WHOIS records are, what kind of data they provide (e.g., name servers, creation and expiry dates, registrar info), and how WHOIS Trackr simplifies the lookup process. ### What Is WHOIS Data? WHOIS is a protocol that queries databases to return registered users or assignees of a domain name or IP address. ICANN requires domain registrars to maintain accurate WHOIS data, and it’s publicly accessible through tools like WHOIS Trackr. ### Common Use Cases: - Verifying domain ownership before a purchase - Investigating phishing domains - Confirming registration and expiry dates for domain management WHOIS Trackr gives you real-time access to this data with a fast, no-cost interface and API access for integrations.
