Which command provides information about network connection details?

1. tcpdump

2. nslookup

3. ipconfig

4. netstat

The correct answer is: netstat

The command that provides information about network connection details is netstat. This command is widely used to display active network connections, including TCP and UDP ports, their states, and the addresses of both local and remote hosts. By examining this information, users can gauge network activity, identify open ports, and troubleshoot network-related issues. When using netstat, you can obtain a comprehensive overview of all active connections to and from your machine, which is crucial for diagnosing network problems or monitoring network performance. It also helps in identifying potential security threats by revealing any unexpected connections that may indicate unauthorized access or services running on the system. While other commands listed serve specific purposes—tcpdump captures and analyzes network packets, nslookup queries DNS to resolve domain names into IP addresses, and ipconfig provides configuration details related to the network interfaces—the focus of the question is specifically on retrieving information related to active network connections, which netstat is designed to do effectively.
