Last of the IPv4 Addresses Allocated

Ah, excellent!

I'm starting to hear "404" in everyday speech more and more, as a general synonym for "lost", "invisible", or otherwise unavailable, among people who haven't the foggiest idea where it came from.

IPv6 is 2^128. It’s a truly astounding number of addresses.

Absolutely. I'll bet you that we'll run out of them in our lifetime though because of how horribly inefficient the allocation of those addresses will be.

I personally know of two large companies and at least one major university each using HUNDREDS of public IPs for their (private) LANs. THAT is why we're out of v4 addresses, because of nincompoops who didn't get the memo about using private network address space (10.x.x.x, 172.16.x.x-172.31.x.x, 192.168.x.x) on their LANs, and the arrogant jerks who are intentionally hoarding far more public addresses than they could ever use.

There should be a simple rule requiring proof of actual, public devices using public IPs or they must be forfeited back to IANA.

There would BE no shortage if not for those two groups of addressees.
