Exam 312-50v11 topic 1 question 71 discussion

WHOIS is a protocol and a database system that provides information about registered domain names, IP addresses, and autonomous system numbers on the internet. It allows individuals to query the ownership and other details of a domain name, IP address, or other internet resources. This information is publicly available and is used for various purposes, including identifying domain name owners, verifying domain availability, and investigating potential misuse or abuse of internet resources.

WHOIS is the protocol and it is asking for the Database. But IANA is the Authority responsible for the coordination of DNS rooting, and other internet protocol resources. Not 100% clear, but I go with A. WHOIS, it access the database.

Hacking Phase: Reconnaissance Searching for the target company’s web site in the Internet’s Whois database can easily provide hackers with the company’s IP addresses, domain names, and contact information. (P.49/33)

According to CEH book it looks like Whois. Whois Footprinting > Whois Lookup > This protocol listens to requests on port 43 (TCP). Regional Internet Registries (RIRs) maintain Whois databases, which contain the personal information of domain owners. For each resource, the Whois database provides text records with information about the resource itself and relevant information regarding assignees, registrants, and administrative information (creation and expiration dates).

EC Council Module 1 page 32 " Searching for the target company's website in the Internet's Whois database can easily provide hackers with the company's IP addresses, domain names, and contact information."

Sorry guys, but I think the 'A' should be the correct answer. "Searching for the target company's web site in the Internet's Whois database can easily provide hackers with the company's IP addresses, domain names, and contact information." In the CEHv11 online book they were multiple times refered the "whois database" , but only a couple of times for the IANA, which by the way is the handler of the well known ports, etc. In this particular case, the "WHOIS" should be the right answer.

A la kot

I'll go with IANA, The IANA WHOIS Service is provided using the WHOIS protocol on port 43. See this site : https://www.iana.org/whois

An ambiguous question. WHOIS - yes, this system contain these info... IANA - yes, same, but IANA provide IP addr to Domain, response for ROOD DNS and more... Stupid question...

A is Correct

The correct answer should be C.IANA, not Whois. Whois is a protocold and command to query the databses, no the databse itself.

A is correct: Taking from CEHv11 page 49, Searching for the target company’s web site in the Internet’s Whois database can easily provide hackers with the company’s IP addresses, domain names, and contact information. IANA can't provide contact information, IANA is responsible for the global coordination of DNS Root, IP addressing, and other Internet protocol resources

Whats correct for this? IANA or WHOIS? both seems correct to me!

be careful with this one! I think the more correct answer here is IANA actually... https://en.wikipedia.org/wiki/WHOIS

correct
