Each router has 2 IP addresses: an internal IP address and an external IP address.
Notice the dashed line in the image below. The dashed line represents the division of two different IP addresses in your router.
We have two software tools that can find your router's IP address. Both of them are free downloads. You can use the free software tools or the windows command prompt to find your router's IP address.
To find your routers internal IP address the easiest method is with a little command line tool called ipconfig that comes with Windows. First you need to click Start and find the Run command. You should see a little run dialog box that looks something like this.
In the run dialog box type in cmd and either press enter or click the Ok button. You should see a black window with white text, referred to as a command prompt.
At the command prompt type in ipconfig and press enter. You should see results that look like the following image.
I have circled the routers IP address in red in the above image. Notice that windows lists it under the title Default Gateway.
REMEMBER: This is the IP address that you use to configure your router for port forwarding.
The easiest way to determine your routers external IP address is to visit a website that reports it back to you. We do that for you. Below is your real external IP address as of right now.
