You don't see them (hopefully), but they're there. Ideally, there are firewalls all around you, even now. Free online course: RHEL Technical Overview.That's because your home router actually has two addresses: one public and one local, and the public one shields the local one from being detected by the internet, much less from being confused for someone else's 192.168.1.1. One of those is probably the same number as your home router, yet when I navigate to 192.168.1.1, I reach my router's login screen and not your router's login screen. For instance, my home router's local IP address is 192.168.1.1. This is possible because of local addresses.Īll local networks in the world use the same address pools. In fact, there are more networked devices in the world than there are IPv4 addresses, and yet IPv4 continues to function. Currently, most of the world (still) uses an addressing system called IPv4, which famously has a limited pool of numbers available to assign to networked electronic devices. The first thing you need to understand is the difference between a local internet protocol (IP) address and a public IP address. This means you need to be able to route traffic from the internet into your local network-correctly and safely.
There are both technical and security reasons for this, but sometimes you want to open access to something within a local network to the outside world. If you've ever tried installing a service, such as a web server or a Nextcloud instance at home, then you probably know from first-hand experience that, while the service is easy to reach from inside the network, it's unreachable over the worldwide web. Ideally, most local networks are protected from the outside world.
