What network utility is available in both Windows and Linux to display open network connections?

Netstat is a network utility that provides detailed information about network connections, routing tables, and protocol statistics. It is available on both Windows and Linux operating systems, making it versatile for network management tasks across different environments. By using netstat, users can view open ports, established connections, and their current status, which is crucial for troubleshooting network issues or monitoring network activity.

The other utilities mentioned serve different purposes: Ping is used to test connectivity to a specific IP address, Traceroute tracks the path packets take to reach a destination, and Ipconfig is specific to Windows for displaying network configuration settings. These tools do not provide the same detailed insights into open network connections as netstat does.
