What does the Netstat command primarily do?

The Netstat command primarily displays all active network connections on a computer. When executed, it provides information about both incoming and outgoing connections, along with their current status. This includes details such as the local and remote IP addresses, the port numbers, and the state of each connection (e.g., listening, established, or closed). This information is crucial for network troubleshooting and monitoring, as it allows users to see which applications are using network resources, identify potential unauthorized connections, and assess the overall health of the network.

The other choices involve different functionalities that are not related to what Netstat does. For instance, converting IP addresses to domain names pertains to DNS functionality, configuring network settings is handled through various network configuration commands, and managing software updates typically requires a completely different set of commands or tools specific to the operating system's update system.
