A Linux user needs to display their system’s IP address and network configuration details. Which command should they use?

Traceroute is a network diagnostic tool used to track the path that packets take from one host to another. While it can provide information about the network route, it does not display the local system's IP address or its network configuration details. Therefore, it is not suitable for the user's needs in this context.

Netstat is used for displaying network connections, routing tables, and various interface statistics. Although it provides useful information about network activity and connections, it does not directly present the IP address or the detailed configuration of network interfaces, making it less relevant for the user's request.

Ping is a command used to test the reachability of a host on a network and to measure round-trip time for messages sent from the originating host to a destination computer. While it can confirm network connectivity, it does not provide the user's IP address or detailed network configuration information, making it an inappropriate choice for the user's requirement.
