Explanation

'netstat -ano' combines three flags: '-a' displays all active TCP/UDP connections and listening ports; '-n' shows IP addresses and port numbers in numerical form instead of resolving hostnames; '-o' appends the owning Process Identifier (PID) for each connection. Together these flags provide a complete view of all network connections, their states, and the process IDs responsible - essential for incident response. '-r' shows the routing table, '-b' shows the executable involved (requires elevation), and '-s' shows per-protocol statistics.
