Find the IP address of your computer, the subnet mask or default gateway of your Internet connection to troubleshoot connectivity issues. If you call your ISP’s technical support department, the representative will likely ask you for this information. The default gateway IP address is also used to access your router’s administration application from your computer. You can view the IP address, subnet mask and default gateway (DNS server) using a command in the command window on Windows Vista.

Step 1

Click the Windows “Start” button to display the Search input box.

Step 2

Type “cmd” into the Search box and then press “Enter.” A list of results is returned.

Step 3

Right-click on the “Command Prompt” entry and then click “Run as Administrator.” Click the “Continue” button if the User Account Control dialog box opens. The command window opens.

Step 4

Type “ipconfig” at the command prompt and then press “Enter.” The Windows IP Configuration list displays. The IP address of the computer, along with the subnet mask and default gateway, are listed on the screen. The IP address for the DNS server is the same as the default gateway IP.
