Finding Your Public Internet Address

You cannot tell someone on the internet to connect to you using an address that begins with 192.168.x.x or 10.x.x.x because this is the private LAN address of your computer. You need to tell them your public/real IP address instead, which can be obtained as follows.

1. On the computer acting as the router (sharing the internet connection), click the Start menu, then "Control Panel".

2. Click on "Network and Internet Connections" then "Network Connections".

3. A list of network adaptors is shown. Double-click on the network adaptor that represents your connection to the internet.

4. Click on the "Support" tab.

5. The address is where it says "IP Address:" on the Support tab.
