For those of you unfamiliar with the issue and how the internet works (in simple terms) each and every connected device on the internet needs an IP address. It’s like a phone number, basically a unique number given to your computer, mobile phone, or whatever, whenever it is connected to the internet. It then “dials” another number whenever you check your email, go to a web page or any other activity.
Of course, to dial a number you need a number your self. And as we all know the number of connected devices on the internet is by no means slowing down. So we need more numbers to allocate to these devices. But here’s the catch: There are no more numbers available.
