IPv4 Will Not Die In 2010

darthcamaro writes "A couple of years ago, the big shots at IANA (that's the people that handle internet addressing) issued a release stating that the IPv4 address space was likely to be gone by 2010. Here we are in 2010 and guess what, IPv4 with its 4.3 billion addresses will NOT be all used up this year. In fact there could be another two years worth of addresses still left at this point. 'We're at about 10.2 percent (IPv4 address space) remaining globally,' John Curran, president and CEO of ARIN said. 'At our current trend rate we've got about 625 days before we will not have new IPv4 addresses available. We're still handling IPv4 requests from ISPs, hosting companies and large users for IPv4 address space, but that's a very short time period.'"

      NAT is a blessing. It allows people to access the net without being exposed to it.

      Someone should write some software that can be put on a router that would offer the same protection without also causing all the problems that come with NAT. It would be like this large barrier that burns up any unauthorized data that tries to get by.

      No, this sums it up. If you'd bother to read this or an estimation done by someone else, then you'd know that the uncertainty is less than 3 months with high confidence. Of course the 625 days thing is bullshit, but saying 1.5 years +-3 months is probably what will happen, unless something really major changes don't start happening in the IPv4 process, which I wouldn't say is too likely based on the fact that it would require immediate global cooperation (see how well that went in Copenhagen).

Out of the 256 "/8s" only 219.914 /8 is theoretically usable, even before subtracting the legacy allocations. The summary makes it sound like it was a doom-and-gloom prediction that didn't happen to be true, but that's not the case.

    Also, it's "not the next 2 or 3 years", based on the available number of addresses 1.5 years for the IANA pool and 2,5 years are hard bars until RIRs (regional internet registries) run out.

    It's also the point at which the market for IP addresses opens, and companies start selling subnets.

    No. Repeat after me, there is no market in IPv4 addresses. The current rule is that when a RIR requests a block from IANA that would bring the IANA pool below 5 /8s, then every RIR gets one last /8 from the "final five". Then IANA is done and the RIRs have whatever addresses they have left in their unused pool. For AfrNIC it'll last decades, for APNIC/ARIN it's curtains in about a year.

    There is no market in IPv4. There never will be, because reclaiming addresses is too hard and routing can't handle it atm (routing too small blocks). Let's switch to IPv6 already, for fuck's sake, we'll have to do that anyway even if a miracle happens, technical problems get worked out and someone sets up an IPv4 market, about 6 months after.

    IPX won't die in 2010, either.

    But, in all seriousness, there's a few things to remember here.
    1. The v4 address space will be exhausted in the foreseeable future.
    2. Reclaiming large blocks only delays that inevitability by a few months.
    3. With a few exceptions, modern, supported OSes (Windows [2003, 2008, Vista, 7], GNU/Linux, all of the BSDs, OS X) support IPv6 perfectly.
    4. Most of the critical applications support IPv6 perfectly.
    5. The big holdup on the consumer side has been with the ISPs. The DOCSIS 3.0 roll-out is ongoing in many places.
    6. The US government has mandated it. The compliance date was in 2008 for all of the Federal agencies on their backbones. It's just a matter now of getting ISP access to those sites, and configuring lower-level systems.

    The luddite attitude here about this is amazing. If you're really all that concerned about it, and don't want to focus too much on the nuts-and-bolts, here's some advice: Learn BIND. Setting up your resolvers properly will spare you headaches.

    I use IPv6 every day. I get lots of e-mail over IPv6 (netbsd and freebsd mailing lists, to name just a couple). I enjoy being able to ssh to all of my machines at home directly. It's here. Evaluate your crap, and see what's not going to work. Plan to replace that stuff. Most of it probably will need replacing by the time you get assigned a /64 or /48 by your ISP, anyway.

    Yes there are a lot of ipv6 addresses, however looking at the total size of a 128 bit address space is very misleading as ipv6 addresses are designed to be allocated in a more heirachical manner and designed to support stateless autoconfiguration for clients. Originally end sites were meant to be allocated a /48 though ripe now seems to be pushing for smaller allocations to smaller end sites.

    Plus only 2::/3 is assigned to the ipv6 internet with other address space being reserved for other purposes.

    Those figures would give us 2^45 end sites, this should be enough that we don't run out of addresses any time soon but it's a lot less than the ammount people assume from just looking at the number of bits in the IP.

    There are going to be lots of little solutions that will stretch out IPv4 for a while.

    One that I came up would be to offer a financial incentive to reclaim unused blocks of addresses. Ten or fifteen years ago, IP address space was handed out like candy. You could get a class C block readily, and class B blocks just needed a little justification. I did some contract work in the late 90s for a company that I still keep up with, and they have a few entire C nets in their possession and not in use. Now how do we get these back? There is going to be demand for IP addresses, and as the supply becomes more and more limited, that demand will make people desperate.

    So why not let people who already have address space sell what they have? It does reward unrightfully holding onto stuff, but if these addresses are needed, then hey!

    You could easily use 64 bit addresses in IPV4 by sticking the rest of the source and destination addresses in the options field of the packet. But why? We would still need to upgrade all the routers and software to work with the new system, except we would be upgrading to a hack not a solution, and we would be ignoring the solution that has already been implemented in many computers around the world. As likely as not, IPv6 already works with the computer you are holding, it just needs to be turned on.

    IPv6 is the way to go, and everyone is already heading that way. By the time IPv4 addresses run out, the biggest difficulty may be explaining to your friends how to fix their internet that is no longer working and they don't know why.
