What Happens When IPv4 Address Space Is Gone 520

darthcamaro writes 'We all know that IPv4 address space is almost all gone — but how will we know when the exact date is? And what will happen that day? In a new report, ARIN's CIO explains exactly what will happen on that last day of IPv4 address availability: '"We will run out of IPv4 address space and the real difficult part is that there is no flag date. It's a real moving date based on demand and the amount of address space we can reclaim from organizations," Jimmerson told InternetNews.com. "If things continue they way they have, ARIN will for the very first time, sometime between the middle and end of next year, receive a request for IPv4 address space that is justified and meets the policy. However, ARIN won't have the address space. So we'll have to say no for the very first time."'

          That's not necessary, IPv6 already has the IPv4 address space blocked off and reserved for IPv4 addresses, so all you need is protocol translation for the systems that can't understand IPv6. It's not a hard problem. Yeah it will cost a little money, but really it's a drop in the bucket compared to everything else a business needs to deal with.

          You band-aid it until you can justify the necessary overhaul. Eventually everyone will be on IPv6.

          In other words, the reason nobody is rushing to fix it is because it's not that big of a deal. The problem is small enough that you won't really need to worry about it until it actually comes up.

IPv6 is better if you have a higher pressure internet, as it can move a greater volume but only if you support it. Lots of people are trying to squeeze their devices onto the intertubes, so the pressure of all of those electrons is really high. This clogs IPv4, freezes the electrons, and causes the web to burst.

      Fact of the matter is, nobody's moving to IPv6 until they *have* to. We can cry doom and gloom all we want (we have been, after all), and nobody cares. When Comcast can't address new customers, they'll get off their ass.

      Hmmm, maybe that's part of the problem? They never say no to anyone.

      They definitely say no. Not only that, if the utilization of your existing IP space drops below a certain threshold, ARIN will start taking it back. And they won't take back your emptier networks, they'll take back whatever they want (usually the largest ones, i.e. the ones you most want to keep). They also no longer issue anything bigger than... I think a /22? It might even be smaller.

      Everybody except ARIN was always like this, of course. ARIN could afford to be more generous because the US has a disproportionately large number of IPs for its population (and even for its server count). But now they're in the same boat as APNIC and RIPE, so they've gotten much stricter than they used to be.

    • Address space shouldn't be a scarce resource. The only reason that it is presently behaving like one is because of the cost associated with transitioning to IPv6. However, it really isn't ARIN's responsibility to regulate allocation based on need. Everyone is going to have to transition to IPv6, might as well happen sooner rather than later.

      Too late. Hindsight is 20/20, etc. Does MIT really need a /8? No. Does HP need two? No. But as with any scarce resource when no more IPv4 addresses are available they will rise in value and people will auction off their space. The price will have an upper bound at the cost of deploying IPv6. That'll buy us another few years. And then people will NAT even more. That'll buy us a few more. And by that time most people will be ready to move to v6. There really is no need to panic here. I'm not sure where all of the anxiety stems from. The people that understand the issue and care about it are aware of it and on top of it. I suspect an ulterior motive.

      The Internet was designed so that any computer could connect to any other computer. This is evident in the design of things like FTP, etc.

      Every phone, watch, fridge, TiVo, computer, and printer should have a public IP address. Imagine if you didn't need to port forward for Bittorrent, if Skype could connect right to your friend's computer, or you could print to your home printer by just entering its address. That's how the internet was/is supposed to work.

      NAT breaks this. Behind a NAT box, nobody can address a specific computer - only the NAT itself. This happens to lend some security, but is essentially accidental. With IPv6, your home router will instead be a firewall. Each computer will be addressable, but will still need to pass through.

      Plus, there's enough address to give each subscriber many thousand. And they don't need to change. No more charging for a static IP...

      Also, routing is more efficient since it can be done properly by hierarchy.

Replacing the router infrastructure and the configuration tools for stable, legacy systems to support IPv6 is expensive and the benefits of IPv6 are frankly underwhelming. It's exciting "auto-configuration" is, in most cases, a horrendously bad idea for public facing systems, and private systems don't need it. Useful security features, such as IPsec, were backported to IPv4. And the robust technical features of IPsec seem to be overwhelmed by the far easier to use client behavior of PPTP.

    Multicast? Oh, dear. Do _not_ get me started on the flaws of multicast programmers decided that the lack of information about missed packets in multicast forcing them to rewrite TCP, badly, as an unstable software layer on top of multicast.

    I just relocated to Virginia and to my surprise, Comcast is providing IPv6 addresses on their residential links. I'm going to activate IPv6 on my dd-wrt router and all my PCs sometime this weekend.

    There are currently two companies forcing the hand of the consumer ISPs to adopt IPv6.

    Since February this year Youtube has put all the actual media reachable on IPv6 as default when you access the youtube website through their normal DNS name.
    Apple's time capsule and airport extreme by default sets up IPv6 through tunnels.

    This means that a lot of people with Apple computers browsing youtube movies are heavy users of IPv6.
    As there are only a few tunnel brokers, the load on those will be quite high.

    ...and we can watch the nerds scramble to upgrade their home and work enterprises so they can access it. :-P

    I'm joking, or at least I think I am. If Slashdot did that I'm sure I would put more effort into getting an ipv6 address.

    I was part of Open Systems Interconnection, OSI. We were pushing one of those many technologies like XNS, CHAOSnet, DECnet, IPX, SNA, and ATM/SONET that 'competed' with TCP/IP (NCP had been beaten back by then;^). Before the days of NAT, I had a "very persuasive" presentation that showed the Internet running out of 32-bit IP addresses by 1995 (China and India were my big closers that silenced a lot of TCP wonks). OSI had a 'better' addressing scheme that did everything -- distinguished end systems (ES) from intermediate systems (IS), facilitated class of service, extended addressing to the transport/session/presentation layer services, incorporated MAC layer addressing, facilitated source routing, provided network management hooks, and would give you a blow job that pealed the cover off a plenum cable. It was the ultimate networking addressing scheme. The routing vendors, who were accustomed to shoving the whole network layer address into a 32-bit register, said they couldn't implement a 20+ byte NSAP address, even though they only had to route on a small portion of it. In the 1980s, that was probably true. Most of OSI died (X.500, ASN.1 and a few others survived), partly due to its massive scope (like ADA), and partly due to the fact that the authors ignored the IETF and most of the people who implemented the Internet. Much of what OSI tried to do is now being done by the IETF on their own schedule and their own mandate. To the victors go the spoils and the spillage.

    I paid thousands for 127.0.0.1 years ago in anticipation of this. Cha-ching!

It is easier to write an incorrect program than understand a correct one.
