Which command can be used to display all active network connections and listening ports?

The command that effectively displays all active network connections and listening ports is netstat. This command provides a detailed overview of current TCP/IP connections, including the local and remote IP addresses, port numbers, and the state of each connection (e.g., established, listening, etc.). It is a valuable tool for network troubleshooting and monitoring, as it allows users to identify any unauthorized or unexpected connections that may indicate security issues or performance problems.

In contrast, the ipconfig command is primarily used to display and manage the configuration of network interfaces, including IP addresses, subnet masks, and default gateways, but does not show active connections. The ping command is utilized to test connectivity between devices on a network by sending ICMP echo requests and receiving echo replies, and it is not concerned with listing active connections. The arp command is used to display and manipulate the Address Resolution Protocol (ARP) cache, which maps IP addresses to MAC addresses, but it does not provide information on active connections or listening ports.
