Certified Ethical Hacker (CEH v11) — Question 125

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 ARIN, which stands for American Registry for Internet Numbers, a resource used to obtain information about IP addresses and network allocations. DuckDuckGo and Baidu are search engines that do not provide detailed network information, while AOL is an internet service provider not focused on this type of data retrieval.
