Which command can help identify all current connections and listening ports on a system?

The command that can help identify all current connections and listening ports on a system is netstat. This command is a powerful network utility that displays the status of network connections, including both incoming and outgoing connections, alongside data about listening ports.

When executed, netstat provides a list of active connections, which includes the local and remote IP addresses along with the port numbers, and shows the state of each connection (such as established, listening, or closed). This information is crucial for network diagnostics, security monitoring, and troubleshooting connectivity issues.

In contrast, other options such as route, ipconfig, and tasklist serve different purposes. The route command is used for displaying and manipulating the IP routing table, ipconfig is primarily for displaying network configuration details like IP address, subnet mask, and default gateway, and tasklist is used to list all currently running processes on the system. Each of these commands is valuable in its own context but does not provide the network connection details that netstat specifically offers.
