If you follow CNN, you’re almost certainly already aware that, due to a shortage of IP addresses, “the internet might stop working.”
I just wanted to take a moment to make three quick points:
1) The Internet is not going to stop working when we run out of IP addresses. In fact, that whole idea is incomprehensibly dumb.
2) There are PLENTY of IP addresses!!
Okay, get this… There are fewer than 300 million internet users in the world. There are over 4 BILLION IPv4 addresses.
Get it? There are plenty of addresses. The problem is not the number of addresses. The problem is that the crackheads assigning them don’t care whether or not they end up being utilized. What an incredible (and expensive) waste.
3) There is a very simple solution to this that doesn’t involve spending billions of dollars on forcing the world to move to IPv6 before it’s ready:
ARIN should just start reclaiming unused IP blocks.
It’s that simple. It really is.
Ping each IP address, and if there’s no response, check a few ports.
Use that data to create a utilization metric for each IP block.
If the IP block is underutilized, or not used at all, simply recover part or all of the IP block for someone else to use.
That’s it. That’s all that has to be done.
People are idiots.
