How Can I Secure My Router If I Don’t Know It’s IP Address?

If you have a router you have most likely bought it yourself or been given it by your ISP. In those cases you should already have it’s IP address as it will have been included in the documentation that came with it. But what if you have lost/forgotten/never had the router’s IP address?

How Can I Secure My Router If I Don't Know It's IP Address?

Well, fear not, for there is an easy way to find out what it is. And need it you will if you want to access the router’s interface to make changes to it’s configuration, including security settings.

Discovering a router’s IP address

Firstly, you need to be using a Windows machine (sorry Mac fans). Press the ‘Windows’ button (which can be found between Ctrl and Alt¬†keys on the bottom left hand corner of your keyboard) and ‘R’ together. A box will appear, as seen below, and you need to type ‘cmd.exe’ in as shown:

cmd.exe

Now click on the ‘OK’ button and you will be presented with a rather black looking screen with a command prompt. Here you need to type ‘ipconfig’ as seen below:

ipconfig

Now hit your return key and you will be presented with the information that you need, as well as other details such as your own computer’s IP address. What you are looking for in this instance though is the router’s IP which is the number next to ‘Default Gateway’:

router IP address

In my case you can see above that the router I’m using has an IP address of 192.168.0.1 and that I am connected to it via an ethernet adapter and cable.

You should note at this point that there may be more than one Default Gateway present, especially if you have both an ethernet port and a wireless card in your machine so make sure you know which you are using just in case they are displaying different results.

Now that you know your router’s IP address you can now login to it’s web interface (as long as you know the username and password, both of which can be reset and then Googled if necessary) and make the changes necessary to secure your router.
