Which command-line tool is primarily used for displaying network statistics and active connections?

The command-line tool that is primarily used for displaying network statistics and active connections is Netstat. This tool provides detailed information about the network connections on a computer, including current TCP and UDP connections, listening ports, the routing table, and other network statistics. Such information is crucial for diagnosing network issues or understanding network activity on a machine.

Netstat's output helps users see which applications are using the network and can assist in identifying unwanted connections or issues with network traffic. It can also show statistics for different protocols, making it a comprehensive tool for network monitoring.

Other tools mentioned have different purposes: Ping is used to test the reachability of a host on an IP network, Traceroute is designed to trace the path packets take to their destination, and Ipconfig provides configuration details about the network interfaces on a Windows system, including their IP addresses. While these tools are valuable for network troubleshooting, they do not focus on displaying detailed statistics and connections like Netstat does.
