Certified Ethical Hacker (CEH v12) — Question 51

Clark, a professional hacker, was hired by an organization to gather sensitive information about its competitors surreptitiously. Clark gathers the server IP address of the target organization using Whois footprinting. Further, he entered the server IP address as an input to an online tool to retrieve information such as the network range of the target organization and to identify the network topology and operating system used in the network.
What is the online tool employed by Clark in the above scenario?

Answer options

Correct answer: C

Explanation

The correct answer is C, ARIN, as it is a regional internet registry that provides information about IP address allocations, including network ranges and organization details. The other options, DuckDuckGo, AOL, and Baidu, are search engines or web services that do not specialize in providing detailed network information related to IP addresses.
