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."

    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.

    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.

    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.

New devices (mostly) universally support IPv6, which has plenty of unallocated IP Space (we can allocate 200 quadrillion IPv6 addresses per square inch of land on the planet) popular and actively maintained services either have already, or will soon move over to providing services on an IPv6 address. ICANN has already switched over their root DNS Servers to resolve IPv6, and most larger ISPs are following suit. So, if you've got a new device on an ISP who has updated their DNS servers to work with IPv6, and you're accessing a popular website that has been updated to IPv6, you might already be using IPv6 and never notice the difference.

    There's a lot of ifs in that statement though. Plus there's a pile of legacy OSes and TCP/IP stacks that won't work with IPv6, so while you might be able to access Amazon, Google, and Facebook, it may be that your corporate payroll system is run off an old Windows NT4 system, which isn't IPv6 capable, so your whole corporate network is held up on the IPv6 migration because that NT4 system isn't IPv6 capable, and the payroll system isn't compatible with Windows Server 2008.

    Plus, even some modern equipment/software from low-price vendors is lacking IPv6 support, because it hasn't been cost-effective to add it.

    Eh, not really. IPv4 will be gone. If you are an ISP, and you pursue Carrier Grade NAT (CGN) as your solution, you growth limit yourself. It's equivalent to fixing your available bandwidth permanently - you can't add more customers past a certain point without significantly degrading performance for all customers. In a few years, you'll need to deploy IPv6 anyway; your customers will pay a price for the capital cost of your CGN gear, then your customers will pay a further price for the capital cost of your v6 gear.

    If you're only concerned about web+mail, deploy dual stack lite. Browsers and mail clients do IPv6 transparently already. CPE devices support v6 out of the box at the sub-$100 price range (Netcomm, Billion, and, uh, the one used in the big v6 trial by xs4all in the Netherlands). Going DS-Lite means that as more software supports v6, and more services appear on v6, the pressure on your public v4 addresses drops over time. You can sustain DS-Lite throughout transition. The capital cost is similar to CGN, and the ongoing expenses of v6 are generally covered by your existing v4 expenses (ie, bits you pay going over a v6 session are bits you no longer pay for over your v4, and if your upstream is charging you more for v6 it's time to go provider independent!)

    Some of the services that don't work over CGN include, by the way, XBox Live, BitTorrent, many network games, and most VOIP solutions. Some services do work over CGN, but rely on a reasonable proportion of Internet users having a public address to do so, and thus aren't long term viable: Skype, some of the smarter BitTorrent clients that do hole punching. Some services rely on emerging protocols for dealing with CGNs, like FaceTime: ICE, STUN, and TURN.

    You can get a taste for life under a CGN by configuring your home NAT device to ignore uPnP requests, and disabling any manual forwarding settings.

    Also, the summary is full of shit regarding the changing estimation. The linked articles are pretty clear that it's still early 2011. Available metrics (http://www.potaroo.net/tools/ipv4/ is one of the best) show a pretty unchanging date; that link, in fact, includes a few graphs down the bottom showing the change in predicted date over time. If you're an ISP, you've got a reasonably reliable date to plan around, and it should see you unrestricted on your IPv4 clear through to 2012, plenty of time to get ipv6 upstream (typically free or very cheap, when taken alongside your v4) and implement dual stack in your core.
