A certified ethical hacker is conducting a Whois footprinting activity on a specific domain. The individual is leveraging various tools such as Batch IP Converter and Whois Analyzer Pro to retrieve vital details but is unable to gather complete Whois information from the registrar for a particular set of data. As the hacker, what might be the probable data model being utilized by the domain's registrar for storing and looking up Whois information?
A Thin Whois model stores only limited information about a domain name, mainly the name of the Whois server of the registrar. Since the individual is unable to gather complete Whois information, it is likely because the data model in use is the Thin Whois model, which does not hold complete details but refers to the registrar for additional information.

Selected Answer: A What is a Thin WHOIS lookup?

The remaining data, that being the contact details, are stored directly at the holding registrar(OpenSRS). Examples of this would be .COM and .NET, which soon will be moving to thick WHOIS as per the articles above at ICANN. What is a Thick WHOIS lookup? A thick WHOIS lookup contains all the technical data with the registry, as such administrative and technical, owner contact details. In addition, the sponsoring registrar and registration status.
