You may know IPv6 is ridiculously bigger, but you don’t know it.
There are enough IPv6 addresses that you could give 10^17 addresses to every square millimeter of Earth’s surface. Or 5×10^28 addresses for every living human being. On a more cosmic scale, you could issue 4×10^15 addresses to every star in the observable universe.
We’re not going to run out by giving them to lightbulbs.
He’s too big a chicken for that.
