Here in part 2, I'm going showing why these duplicate addresses don't cause chaos when messages are sent across the internet. Let's use an example to show how items can communicate successfully even though they share the same address. Say your laptop has an IP address of 192. 168. 1. 5 and your wireless internet CCTV camera comes with a address of 192. 168. 1. 101. Let's also say that the neighbour's laptop has, by coincidence, the same tackle as your laptop: 192. 168. 1. 5. Before we go any longer, you may be thinking that the odds of the following are infinitesimally low. Well, actually they are not necessarily. This is because the majority of home networks have IP addresses that are generally in the same several ranges, often from 192. 168. 0. 1 to help 192. 168. 0. 255 and also from 192. 168. 1. 1 to 192. 168. 1. 255. Into our example, this means that when your neighbour tries to connect with your wireless internet CCTV camera (assuming you have given him the private data), we would find it difficult if only the property networks' IP addresses have been used, because your neighbour's laptop on 192. 168. 1. 5 would send a phone message to your camera at 192. 168. 1. 101, but when the video camera replies, would the reply check out back to your neighbour's laptop on 192. 168. 1. 5, or even your laptop on 192. 168. 1. 5, or someone else's computer somewhere else on the globe that also happens to have a 192. 168. 1. 5 address? Clearly this would not necessarily work, and that's why the web has its own number of IP addresses that are universally unique. Continuing the above mentioned example, when your neighbour's netbook at 192. 68. 1. 5 in his network sends a phone message to your internet video camera, first of all this message will reach their router, which wraps it up making it labelled with your neighbour's sole unique internet IP address, say 74. 5, is never sent across the internet at all. Today, when the message reaches your house, more specifically your router, the router hands it for a wireless internet camera. In this way, home networks throughout the modern world can reuse the exact same IP addresses. There is actually something missing from this explanation that you may have spotted. How does your router "know" that a message coming in ideal for your internet CCTV video camera, if that camera's IP tackle of 192. 168. 1. 101 is not sent in the principles? The answer is that the camera is allocated a "port" number, which is sent while using the message. So your neighbor, when logging into your camera, would type not only your internet IP address of 209. 191. 93. 53 into his browser address bar, but rather 209. Always keep alive or auto-reconnect attribute.
