Explanation

The netstat (network statistics) command displays active network connections, routing tables, and port usage. Running 'netstat -an' (all connections, numeric format) or 'netstat -an | find "LISTENING"' on Windows lists all ports currently in a TCP LISTENING state, showing which services are waiting for incoming connections. 'net use' manages mapped network drives and shared resources. 'nslookup' queries DNS servers to resolve hostnames - it has nothing to do with local port states. 'ping' tests ICMP connectivity to a host. Only netstat provides local port and connection state information.
