 Hello! With this video I want to teach you how to determine if you are using a private IP address or a public IP address to access the internet. We are going to use a tool from NIRsoft NetRouteView. You can find it at this URL. So download this, open the zip file and run NetRouteView. Ok, so here you have all the routes on your machine and a standard machine. You will find a route with destination 0,0,0 and mask 0,0,0. This is the route that will be used to direct your traffic to the internet. So take a look at the interface IP and you can see it starts here with 192.168. So this is a private IP address and from your machine this IP address, all requests to the internet will be sent to the gateway to this IP address which is also a private IP address 192.168. So this is here my network device that gives me access to the internet. Here are the ranges of IP addresses that determine if you are dealing with a private IP address. If your IP address starts with a 10, it is a private IP address. If it lies between 172.16.00 and 172.31, 255, 255, it is a private IP address. And then last one here, if it starts with 192.168, then it is also a private IP address.
