An administrator is troubleshooting connectivity issues and needs to determine the IP address of a website. What is the best command to use to accomplish the task?

Explanation & Hint:

For an administrator who needs to determine the IP address of a website, the most appropriate command to use is:

nslookup

This command is used to query Domain Name System (DNS) servers to find out the IP address associated with a domain name. By typing nslookup followed by the website’s domain name in a command line interface (such as Command Prompt on Windows or Terminal on Unix/Linux systems), the administrator can find out the IPv4 and IPv6 addresses for that website.

The other commands are more specific to network device configurations and are not typically used for resolving domain names to IP addresses:

• show ipv6 route displays the IPv6 routing table of a router.
• show ipv6 interface shows details about IPv6-enabled interfaces on a router.
• copy startup-config running-config is a command used on Cisco devices to copy the saved configuration (startup-config) to the current running configuration; it’s unrelated to DNS queries.
