That’s 4 Billion IP addresses for the whole world: the IP being a set of 4 two or three digit numbers that your computer or internet-connected device uses to route all the information to it’s door. Without them the whole shebang wouldn’t work; like a homing pigeon with no loft.
Anyway the current system doesn’t include enough possible numerical variations to go beyond the original 4 billion arrived at so, a bit like they had to change the London telephone codes from 01 to 071 and 081 as more and more impertinent people wanted a phone line, they are going to have to start changing the format of new IP addresses from four sets of number variations to six sets. Otherwise they will run out next month…
Oh how my poor nerves are wracked by the very thought of it.
I wonder who came up with 4 billion in the first place? Did they even consider China: population 1,341,750,000 or *India:1,198,003,000. What the hell those two numbers are in words, I’ve no idea. Anyway, whichever eejit settled on 4 billion (4,000,000,000,000) it was a bad day at the office for them, and they should be sent to stand in the corner to think about it.
*India’s population predicted to exceed that of China’s by the year 2030.
