Which command is used to view active network connections?

The command used to view active network connections is indeed netstat. This command provides various information about network connections, including the current status of TCP connections, details about the listening ports, and other network statistics. It is particularly useful for diagnosing networking issues or monitoring the network performance by displaying a list of all current connections and their states.

In contrast, ifconfig is primarily used to configure and display network interface parameters, such as IP addresses and network interface status, rather than displaying active connections. Ping is a network utility used to test the reachability of a host on an Internet Protocol (IP) network, but it does not provide a comprehensive view of active connections. Traceroute is designed to find the path that a packet takes to reach a destination and to diagnose network routing issues, not to display active connections. Thus, netstat is the appropriate choice for obtaining a detailed overview of active network connections.
