Very clever technical networking tricks have kept things going. In fact, we began running out in the 1990s. But with all the computers, smartphones, and tablets that connect to the internet, not to mention IoT devices, we have run out of IPv4 addresses. IPv4 has a total pool of 4.3 billion addresses, which sounds like a lot. IPv4 dates back to the early 1980s, when the internet was a private network for the military. When you use a VPN, it prevents your network from revealing your address. In this case, it’s possible to mask your IP address from the outside world through a Virtual Private Network (VPN). You may not always want the outside world to know exactly which device and network you're using. 1, and each subsequent device gets assigned. The Host ID refers to the specific device on that network. The Network ID indicates which network the device is on. So on your home network - 192.168.1.1, for example – 192.168.1 is the network ID, and the final number is the host ID. The parts of your IP addressĪn IP address has two parts: the network ID, comprising the first three numbers of the address, and a host ID, the fourth number in the address.

IPv4 addresses contain a series of four numbers, ranging from 0 (except the first one) to 255, each separated from the next by a period - such as 5.62.42.77. It’s easy to recognize the difference if you count the numbers. There are two types of IP addresses: IPv4 and IPv6. IP addresses do the exact same thing when you’re online - that’s why every single device that is connected to the internet has an IP address. When you contact someone, your phone number identifies who you are, and it assures the person who answers the phone that you are who you say you are. IP addresses are like telephone numbers, and they serve the same purpose. (Internet protocols do other things as well, such as routing internet traffic.) This way, it’s easy to see which devices on the internet are sending, requesting, and receiving what information. The internet protocols manage the process of assigning each unique device its own IP address.
