What does the nslookup command do?

Displays current TCP/IP network configurations
Translates name to IP address
Shows the routing table
Lists all current TCP/IP network connections

The correct answer is: Translates name to IP address

The nslookup command is used to translate human-readable domain names into IP addresses. This can be useful when troubleshooting network issues or verifying DNS configurations. Option A, displaying current TCP/IP network configurations, does not accurately describe the purpose of the nslookup command. Option C, showing the routing table, is also incorrect as this is not a function of the nslookup command. Option D, listing all current TCP/IP network connections, is also incorrect as this information would be provided by the netstat command. Therefore, the correct answer is B, translating name to IP address.
