The correct Internet tool for retrieving domain name-specific information from the NSI Registrar database is WHOIS, which is different from ping, traceroute, and DNS Lookup that serve other network-related functions.
The Internet tool that aids in retrieving domain name-specific information from the NSI Registrar database is c) WHOIS. WHOIS is a query and response protocol used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system. This tool provides a wealth of information, such as the domain name’s availability, ownership details, registration, and expiration dates.
It proves to be effective for various purposes, including network troubleshooting, domain name ownership verification, and ensuring responsible use of the internet domain name registration system.
In contrast, ping is a utility that checks the reachability of a host on an Internet Protocol (IP) network, traceroute is a network diagnostic tool for displaying the path and measuring transit delays of packets across an Internet Protocol (IP) network, and DNS Lookup is a tool that resolves domain names to IP addresses.
Therefore, regarding domain name-specific information retrieval from the NSI Registrar database, the correct tool to use is WHOIS.
