What does it mean in practice? If the hacker’s computer is not directly connected to your local network (Wi-Fi), he cannot access it. This address is not the address of a particular computer, but rather a temporary address of the home router. Just go to, and you will see that all home devices have the same address (Macs, PCs, iPhones, etc.). The same thing happens in your home network, and you can quickly check it. So, instead of using 50 public IPs, all computers in the same local network use only one. But when Bob needs to reach Google, his computer uses shared public IP (one for all local computers). Inside the office, the engineers build a local network with local IPs, such as 192.x.x.x or 10.x.x.x.įor instance, if Bob wants to get access to John’s computer, he uses the local IP. So, in reality, we need just one public-facing IP address, and all computers inside the office share it when making calls outside. The network engineers said that there is no need for each computer in the office to be accessed from outside the office. And one of them, in layman terms, is not to let all computers have dedicated public IPs. So, in reality, we have much less range for use, and also I suspect that the number of devices connected to the Internet is higher than 4 billion anyway.Īll of this led to multiple solutions. Since there is no one central service or entity that gives away IP addresses, we had a situation when most of the range was wasted (for various reasons). In theory, if these numbers were appropriately used, the range would be enough for more than 4 billion devices. Originally, the IP address looked like four numbers ranging from 0 to 255, e.g., 192.168.0.111. The entire idea is based on computers connecting to each other by using IP addresses. I guess you wouldn’t be terribly surprised if I tell you that the Internet was poorly designed.

Now, let me elaborate on all of this on examples of macOS and Windows. If the computer was shut down, then hackers cannot get into it if even it is connected to the power and network. The hacker must know the public IP address, the computer must be either in sleep or hibernate mode, and wake on network access must be enabled. The following requirements must be true for hackers to get into your computer. While cybercriminals have lots of tools in their arsenals, they still cannot break laws of physics. I know some of my friends and family members turn off their devices at night, but even then, they worry what if mighty hackers can get into completely turned off the computer. And it is natural for people to fear being targeted. We hear stories about computers being hacked all the time.
