What command is typically used to check the current TCP/IP configuration on a device?

The command used to check the current TCP/IP configuration on a device is IPConfig. This command provides essential information about the device’s network settings, including the IP address, subnet mask, and default gateway. It is particularly useful for diagnosing network issues, as it allows technicians to see the current state of network connectivity and configurations in real time.

IPConfig works specifically for Windows operating systems, providing a straightforward way to access necessary information regarding network interfaces. In contrast, while other options such as Netstat, TraceRoute, and Ping are valuable diagnostic tools in networking, they serve different purposes. Netstat displays active network connections and listening ports, TraceRoute tracks the route packets take to a specific destination, and Ping tests connectivity between devices by sending packets and measuring response times. However, none of these commands directly provides the configuration details needed to assess the TCP/IP settings on a device, making IPConfig the correct and most relevant choice.
