NRO Warns They Are On Final IPv4 Address Blocks
eldavojohn writes "According to the Number Resources Organization, they will have issued their final twelve IPv4 blocks in a few months. Each block is 16 million addresses and represents 1/256th of the total addresses issued. We are now down to 12 blocks left in the global pool for issuing to Regional Internet Registries, who will then assign the last addresses that will run out sometime later in 2011. The pool of free addresses works out to be less than half of where we were in January. The new numbers from the NRO indicate estimated global pool IP address exhaustion in a few months, a year earlier than they estimated at the beginning of 2010."
When it gets expensive to continue using IPv4, which may not be until well after we "run out."
You're not seeing some magic IP address fairy making them last longer, you're seeing armies of senior IT pros working until after dark trying to sort this all out and deal with things because the pointy-haired bosses on top have been seeing that IPv4 is 'good enough.' As long as IPv4 looks easier and cheaper on paper than IPv6, that's what we'll be using.
You are misstaken, notable predictions have predicted the following:
May 21, 2007: ARIN predicts sometime in 2010
June 20, 2007: LACNIC sets final date to januari 1, 2011
June 26, 2007: APNIC sets the date to sometime in 2010
April 15, 2009: ARIN says sometime before 2011
So for the last 3-4 years there has been a fairly good estimate on when they are supposed to run out.
Less than one year (12 months)
For sure before the end of next year, but probably not by the end of this year.
My bet is in Feb or March of 2011.
Keep in mind, despite having 12 /8 blocks left, that really means 6.
Once there are only 6 blocks left, whoever purchases #6 has ended the game, because the remaining 5 left are automatically to be given to the other world registries at that same moment.
So in reality those last 6 blocks will all go at the same time.
So 6 more /8 purchases and we will be out of space.
They just sold off 12 /8's in the past few months, so it will take half of 'a few months' at the same rate, even though I suspect it will go faster now that there is a crunch for it.
I would not count on it. ISPs are increasingly consumption-oriented services; I would guess that instead of deploying IPv6, we will start to see ISPs offer lower prices for customers who agree to be NATed (or perhaps, demanding higher prices from those customers who refuse to be NATed).
Maybe there is some hope at the universities, though...

You don't want that question answered. Just like when a car's headed for a sheer cliff, you don't want to know exactly when it'll go over it. You want to avoid ever having to have that question answered.
The reason the day of recekoning's been being pushed back is because the IT techies, even as they've been warning of the inevitable cliff, have also been doing everything they can to push the deadline back. They know there's going to inevitably be problems making the switchover to IPv6, and they're trying to buy as much time as possible so we'll have time to fix any glitches, but sooner or later they're going to run out of ideas and tricks and the deadline's not going to move anymore. Ideally by that point it shouldn't matter because we've taken the warning and done what's needed to avoid the cliff entirely. But if everyone keeps assuming that, just because the deadline's been pushed back once, it'll keep being pushed back indefinitely, well, suddenly going into free-fall as the car's wheels pass over the cliff-edge is not a good feeling.
You want really impressive examples? Look back to the big fireball over Cape Canaveral that a few seconds before was STS-51-L (Challenger), or the big fireball over Texas that a few minutes before was STS-107 (Columbia). Challenger blew up because the managers at NASA knew the O-rings were eroding and would sooner or later be breached, and they brushed this off with "Well, it hasn't happened yet so it won't happen ever.". Columbia disintegrated during re-entry because managers at NASA knew pieces of heavy foam insulation were striking the leading edges of the wings during launch and sooner or later one of those strikes would fatally damage the heat-resistant panels, and they brushed this off with "Well, it hasn't happened yet so it won't happen ever.". When we run out of IPv4 addresses the results won't be quite so pyrotechnic, but if we keep saying "Well, it hasn't happened yet so it won't happen ever." we will end up regretting it.
And yet none of those would make more than a dent.
They're allocating /8s, even the addition of several /8s would only extend the time frame by a few to several months, compared to the siginifigant effort required to reclaim them.

Yeah, this gets posted EVERY TIME there's an article about IPv4 address exhaustion, and every time the answer is the same - increasing assignment efficiency will at most buy us a few months, perhaps a year or two, of time. It doesn't solve the problem, only postpones it a little longer.
In truth, when the addresses are exhausted, I expect all the holders of /8's to start auctioning off their unused allotments to the highest bidder. There's a reason none (or most) of them have not given addresses back voluntarily - they are about to become a very scarce, very valuable commodity for trade. Those companies who got in early and got a Class A will make maybe hundreds of millions or even billions of dollars auctioning off the addresses. When companies who have IPv4 address blocks are going into bankruptcy or up for sale, the value of their allotments will start to be accounted for as assets.
Which, I think, is one reason that some tech companies are not pushing harder for IPv6 adoption - they stand to make a lot of money off of artificial scarcity.
Why do we have to have this conversation every single time the issue comes up? gods...
We have allocated 14 /8 networks since January of 2010 (source: http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.txt )....meaning we go through about 1.5 /8s every month. Reclaiming a /8 will take more than a couple weeks, so the simple fact is that reclamation isn't worth the effort: we would burn through several /8s in the time it would take us to reclaim one of them.
To build on this post, we've gone through 14 /8s just since January of 2010. Reclaiming a /8 would buy not even a month, and it would take more than a month to reclaim it.
Reclamation is wasted effort. Implement IPv6.
We will just NAT the NATed NATed NeTed NAT and run the entire internet on a single IP address TRA-LA!
Then there's the free market cool-aid crowd who can't see why bidding wars driving the price of a single IP into the thousands a year is a big deal.
Next up, the "It's so HAAAAAAAAaaaaaRRRRRRRRrrrd!" crowd who don't understand why they should burn their geek card for saying that. That and their close relatives who still haven't realized that very simple firewall rules grant 100% of the security NAT does.
So let me get this straight.. In the beginning we had a very simple very open design. Any host can talk to any other host on any port. Then, over the years bouts of paranoia, fear, and idiocy have created default drop firewalls and nat devices that fundamentally break the open nature of the internet, protocols that rely on that nature break when presented with that stupidity, and somehow it's the fault of the protocol designer?
How would you suggest we operate? Instead of using my internet connection to accept connections from my peers should I proxy through a 3rd party? Should I use a ridiculous hack like upnp to beg the nat device for a forward? What happens when we're all behind default drop inbound firewalls w/ a nat'd address generously provided by our ISP? Suddenly and even though you have an internet connection and I have an internet connection we can no longer communicate directly with each other? Do you not see this as a problem? Is this still a protocol issue?
Here's a decent list of SOHO routers with IPv6 support.
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
They spent HOW long advertising those free-or-highly-subsidized digital converter boxes and people still threw away perfectly functional TVs?
Regardless, no. Both WinXP (unless you're seriously out of date on your software updates) and OS X 10.5 support IPv6 just fine. Of course that's separate from hundreds of badly-coded apps that somehow shoehorned themselves into the IPv4 stack, but that's hardly OS-dependant.
How are sites slashdotted when nobody reads TFAs?
I want IPv4 to run out. The sooner the better. When Y2K was about to come around, all the businesses who had old code some of it from the '60s, started hiring programmers like crazy. They needed to convert all the dates from two digit year to 4 digits. A massive effort but still only a very small amount of the total codebase that was out there needed to be modified.
Fast forward to 2010, 4-byte IPv4 address running out. A new protocol exists but much of the old software and networks cannot use them. The only solution is to hire a massive number of programmers and rewrite the software..
Think of this, every piece of software on every computer that accesses the internet, has to be rewritten. How big is that codebase? A lot larger than Y2K. I can see this pulling in programmer after programmer like some huge vortex, in a race to be done before last address is given out..
You see why I welcome the new of IPv4. The end of the recession in the tech industry and plethora of new job.
If every person in the world had a personal network the size of the Internet, and every machine on it was routable, then IPv6 would still be doing sparse addressing - we'd have used approximately the square root of the possible IPv6 addresses.
