Identifying your IP address, primary DNS and the address for your default router can help you troubleshoot problems with your network connection. Without an IP address, you can't connect to websites on the Internet, while Domain Name Systems translate the domain names you enter into your address bar into a purely numerical address. Usually, your Internet Service Provider assigns the DNS server for your devices. The default router address, also known as a default gateway, is the direct address that you can enter into your Web browser to access the configuration utility for your router.

Step 1

Move your cursor from the top right portion of the screen in a downwards motion to display the Charms bar, and then click the "Search" option.

Step 2

Type "cmd" (omit the quotes here and throughout) into the Search box, and then select "Command Prompt" from the list of results.

Step 3

Type "ipconfig /all" into the Command Prompt.

Step 4

Look at the IP Address field to identify your IP address; the first number in the DNS Servers field is your primary DNS; and the Default Gateway field lists the current default router address used to connect your computer to the Internet.
