WHOIS Protocol Basics

• WHOIS Protocol: An Internet protocol that queries databases to retrieve information about registered domain names, including registrant details, administrative contacts, and technical contacts.
• Query Method: The tool sends simultaneous queries to multiple WHOIS servers (ICANN-accredited registrars) to retrieve real-time domain information.
• Response Time: Bulk queries typically complete within seconds to minutes depending on the number of domains and server response times.

Data Retrieved

• Registrar Information: The company that registered the domain and manages its DNS records.
• Registration Date: The date when the domain was first registered.
• Expiration Date: When the domain registration expires and renewal is required.
• Registrant Information: Owner details (name, organization, location) unless privacy protection is enabled.
• Contact Details: Administrative, technical, and billing contact information associated with the domain.
