This continual whining about how the end of the world is nigh really would make baby Jesus cry.
"A week ago, we reached the magic number of 2.7 billion IPv4 addresses used. With 3.7 billion possible addresses,¹ this means we now have less than a billion unused IPv4 addresses left."
Well, whoop dee fucking doo.
"However, we're now so close to running out that the exact figures don't really matter anymore."
Ach, away and stop havering a load of pish. If people better used what they had, we wouldn't need to be looking at a very fucking expensive upgrade to a hell of a lot of the internet. (New routers, larger routing tables, reconfigure stuff, pray it works. Swear when it doesn't...)
Now, bawjaws briefly talks about RFC 3330 address, a subset of which are RFC 1918 addresses - more on this later...
What he doesn't tell us is who "owns" a metric fuckload of IP addresses.
Now. Let's ask ourselves if these companies (and government agencies) actually need all those addresses which can be routed on the public internet or, if perhaps they could use a combination of CIDR blocks, class Cs and the RFC 1918 address space, mentioned earlier.
If this is the case, then perhaps the Class A networks, /8s, (that's 16,777,214 addresses) could be thrown back in to the pool, and re-allocated to more deserving causes...
Allow me to pick one company at random... Hewlett-Packard. (OK, I was always going to pick them - but does that make me a bad person?) HP has 15/8, 16/8. HP also has a number of Class B networks, sadly not listed in an obvious manner, but trust me, they have them...
Do they need 33 million IP addresses which are routable? Do they fuck. Machines on desks are given IP addresses which are theoretically able to be routed on the public internets. This never happens, because it would be utterly insane to do so, so this is a bloody nonsense, and should be sorted out.
Most large companies barely need a class C per site (office, factory, whatever) - 254 addresses. Remember, we're talking public facing systems here, not internal intranet stuff. You could chop up 10/8 across the international organisation of how many hundred sites? Say a thousand anyway, and you'd still be on waaaaaay fewer IPs than if you'd hogged a class A - or two.
So anyway, the purpose of this rant is to say that guy is havering a load of pish. The end of the world is not nigh. If people did the decent thing, and sorted out their own houses, internet addresses wouldn't run out for ages and ages, and everything would be fab, and my blood pressure would be lower, and I'd drink less.
OK, the last bit was a lie.

"If people did the decent thing, and sorted out their own houses.."
Come on. Who's being naïve now? What are the chances of that ever happening in any field whatsoever.
On a related note, how come the UK Department for the Workshy has ended up with a whole class A?
booga booga booga indeed.
