It's official: Asia's just run out of IPv4 Addresses

Summary: Now, will you take switching over to IPv6 seriously?

Well, that was fast. The Asia Pacific Network Information Centre (APNIC) has just released the last block of Internet Protocol version 4 (IPv4) addresses in its available pool. We knew this was coming when the Internet Corporation For Assigned Names and Numbers (ICANN) and the Internet Assigned Numbers Authority (IANA) announced in February that the last of the world's remaining IPv4 blocks had been assigned to the Regional Internet Registries (RIR). What we didn't know was that APNIC would run out quickly. I, and most other people, thought that its supply of IPv4 addresses would last until at least early summer. We were wrong.

In a statement, APNIC announced that, "This event is a key turning point in IPv4 exhaustion for the Asia Pacific, as the remaining IPv4 space will be 'rationed' to network operators to be used as essential connectivity with next-generation IPv6 addresses (PDF Link). All new and existing APNIC Members who meet the current allocation criteria will be entitled to a maximum delegation of a /22 (1,024 addresses) of IPv4 space. "

So what happened? APNIC Director General Paul Wilson explained the Asia Pacific region is the first to reach the point of being unable to meet IPv4 demand. This is due to the unprecedented fixed and mobile network growth the region is experiencing. "Considering the ongoing demand for IP addresses, this date effectively represents IPv4 exhaustion for many of the current operators in the Asia Pacific region," Wilson said. "From this day onwards, IPv6 is mandatory for building new Internet networks and services."

Now the question is who's going to go next. RIPE, which handles Europe, the Middle East and the former Soviet Union countries? The American Registry for Internet Numbers (ARIN)? I'd thought at one time, ARIN, at least, would hang on to 2012, but now I'm not so sure any of RIRs will make it to the end of 2011 with unused IPv4 addresses.

Owen DeLong head of the professional services division, at Hurricane Electric, a leading IPv6 backbone provider and ISP, told me that now that "APNIC is out now. RIPE is probably next and will probably be in a few months. Counting on IPv4 for continued growth is a dead-end strategy."

DeLong continued, "With APNIC running out this week, it is one more clear wakeup call for anyone thinking that the end of IPv4 growth is not yet upon us. It is real. It is here. It is urgent to deploy IPv6 to minimize the disruption this will cause."

Don't think he's just saying that because Hurricane Electric is in the IPv6 business. He's also saying it because he's dead right. Sure you, or your CIO or CFO, may not want to switch to IPv6, but there's simply not enough IPv4 addresses to go around.

There are work-arounds that make sense. For example, you can use IPv6 on the Internet side of your load balancers or Web servers while behind these devices or servers your intranet's platforms stick with IPv4. The bottom line still though is that sometime soon your business is going to need to at least be able to deal with IPv6 on its Internet connections. You can either wait until events force you into it-and that won't be pretty-or you can start planning on it now.

As DeLong said, "Whether you have enough IPv4 addresses or not, people you need to talk to will probably be pushed to IPv6 in the coming months. As a result, you will need IPv6 connectivity sooner, rather than later. The time to make a planned deployment is now."

Sure you can try to buy your way out by picking up unused IPv4 addresses. But, like John Curran, president and CEO of ARIN, recently told me that while "ARIN will recognize any transfer of address space that meets the policies developed by the community. Parties do not have to make use of ARIN's listing services; those are entirely a convenience to allow others, not ARIN, to match those needing and those with available space." But, I fully expect the prices for IPv4 addresses from such IP address middlemen, such as Addrex, to go way up in the coming months.

Wilson, who's now facing ISPs and customers that are in a panic over APNIC's new IPv4 restrictions said, with little sympathy, "IPv4 exhaustion has been identified as a key turning point for a long time, and it should come as no surprise. Any organization that wishes to remain viable must push forward with their IPv6 deployment." Amen.

Want to buy an Internet IPv4 address? Cheap?

        No wonder that Asia ran out of Addresses. The population of the continent is growing very fast and more and more people have access to web even in their homes. http://www.handyortungkostenlos.eu/Handyortung-gratis/ | http://www.handyortungkostenlos.eu/Kostenlos-Handy-orten/

  • How about...

    Asking people to return their unused blocks, and becoming more efficient with their usage?

      @Yensi717 Return? For free!? It's not happening. IP address blocks are valuable now.

        @sjvn@... True, my hosting provider used to charge 1.99 per ip, now he wants 4.99 per one. These are getting really expensive

      @Yensi717 Why not just do what should have been done 10 years ago and switch to ipv6? Rationing addresses is just plain stupid when if people were just willing to upgrade their systems, they could have as many as they like.

  • What More Can We Do......

    We have made sure all our stuff is ready to roll with IP6, but since our ISP hasn't given us an IP6 block yet, then all the blog posts in the world aren't going to matter.

      @Shmythey Bug your ISP. Better still threaten to go with Hurricane or another IPv6 savvy ISP. They'll get the message.

      @Shmythey We went with a Hurricane Electric Tunnel. Thus far it was worked fine.

      @Shmythey
      We are using COX and we can't even get a time frame for rolling out 6.

  • I don't always like your blogs

    but this was a good one. Thumbs up!

    And yes, IP6 is a f'in nightmare compared to IP4, at least for those of us who natively think in IP4, but we have to change and get moving. It has amazed me at how slowly vendors are moving to IP6. We've been talking about this for 10 years now and everyone I knew would have bet money IP6 would have been the norm last year. We're still not even close.

    • Nobody &quot;natively&quot; thinks in IPv4

      @LiquidLearner

      You're just accustomed to it. It's a learned skill just as IPv6 will be. People will be used to it in a couple of weeks. The hyperbole around how much of a shift it will be for networking types to make the mental switch is staggering.

      • RE: It's official: Asia's just ran out of IPv4 Addresses

        @RationalGuy IP addresses were converted to Base 10 which is kinda our native mathematics.. Ipv6 is Hex, base 16.. its not that easy of a switch. So, technically, we DO think in Ipv4.. more or less. Not saying it won't be easy once its learned, but its quite a lot more to remember than 4 sets of numbers that are less than 256.

    Great article! Very good writeup.<br><br>I've been following yours and others articles on this for the last year- year and a half; and I have been surprised at the exponential increase in speed in which this has come to a head. Certainly faster than most ever forecasted (even when the predictions changed, they still overshot!)<br><br>Our company has done our due diligence to make sure we are prepared, but sadly, until our ISP and our business partners take the same action, it doesn't really do us a whole lot of good.<br><br>Now, if we could just get our Fed. Govt to start developing up-to-date <i>rational</i> technology legislation, we might be making some progress.

    Time to head to my shelter. People, it's been real. Good luck.

    BTW, you can't blame us Cylons here. We've been IPv6 since 2008 :)
