Why Do We Even Need IPv6?
More internet users than ever before know what an IP address is. Slightly fewer know that “IP” is the language of the internet. And while the average internet user probably doesn’t know that everyone’s trying to replace IP version 4 with IPv6, the number who do is growing. But couldn’t we just have gotten by with IPv4?
We need to move away from IPv4 because it’s how we give out addresses for internet devices, and we’re running out. Imagine it’s your job to hand out jersey numbers for a basketball team. What do you do when you have more than 99 players? Jerseys aren’t very wide, you can’t fit “4,385” on the back.
If a device goes to the internet, it needs an IP address. But IPv4 can only provide about 4.3 billion addresses. There are 7.8 billion people on earth, so the problem should be obvious. Fortunately IPv6 can theoretically contain a huge, huge number of addresses: 340 undecillion — or 340 billion billion billion billion — or 340 with 36 zeroes behind it.
That should last us a while.
