The nslookup command is a network administration tool used for querying the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS record. It's the most direct way to verify if a PC can resolve a website's domain name to its IP address.
Here's why the other options are not the primary tools for this task:
* B. hostname: This command displays the hostname of the computer.
* C. tracert: This command traces the route packets take to reach a specific destination. It can help identify network connectivity issues but doesn't directly test DNS resolution.
* D. netstat: This command displays active network connections and listening ports. It's not used for DNS troubleshooting.
How to use nslookup:
* Open a command prompt.
* Type nslookup <website address> (e.g., nslookup google.com) and press Enter.
* The output will show the DNS server used and the IP address(es) associated with the website.
* If the command returns an error or doesn't show an IP address, it indicates a problem with DNS resolution.
