The network address of a Windows device can be determined in two ways. The first method is to open the Command Prompt application and type in “ipconfig”. This will display the IP address, subnet mask, and default gateway of your device. The second method is to open the Network Connections window by pressing the Windows logo key + R, then typing “ncpa.cpl” and hitting enter. This will open a list of all the active network connections on your system. Click the network connection for your internet, then click Details. This will show the IP address, subnet mask, and default gateway for your device.
