Which term describes the specialized Whois service that stores only the registrar's Whois server name?

• A. IP2Location
• B. DNSstuff (Professional Toolset)
• C. Thin Whois
• D. Full Whois

Answer: (C)

The concept here is how Whois data is organized in registries. A thin Whois service stores only the registrar’s Whois server name, with the actual registration details held at the registrar’s own server. This is the thin (or delegated) model, where the central database doesn’t keep full records—queries point you to the registrar for complete information. In contrast, a full (thick) Whois maintains complete registration data in one place, not just the registrar’s server name. The other options aren’t related to this storage model: IP2Location is for geographic IP data, and DNSstuff is a set of DNS tools. So the term described is Thin Whois.
