What does a WHOIS database provide?

Personal information of all internet users
Data on internet traffic and servers
Information about internet domain names and registrants
Comprehensive internet security ratings

The correct answer is: Information about internet domain names and registrants

The WHOIS database is a crucial resource that provides valuable information regarding internet domain names and their registrants. It contains details such as the domain owner's name, contact information, and the administrative and technical contacts associated with a domain. This information is essential for several purposes, including domain management, regulatory compliance, and even cybersecurity investigations. WHOIS databases are publicly available, fostering transparency by allowing anyone to look up who owns a particular domain name. This accessibility aids in identifying domain name squatting or fraudulent activities while also helping organizations to verify the legitimacy of a domain before engaging with it. Thus, the correct answer highlights the primary function of the WHOIS database as a directory of domain name information and registrant details.
