What Happens When IPv4 Address Space Is Gone

Posted by timothy on from the stars-wink-out-one-by-one dept.

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."'

  1. no advantages to IPv6 by davros-too · · Score: 0, Troll
    The reason nobody is adoping ipv7 is that all the so-called advantages of ipv6 are all disadvantages, except bigger address space. If there were some advantage then we would be willing to invest the substantial time and money to switching over.

    * get rid of NAT - I like NAT, it helps me keep the private parts of my network - well - private

    * auto-configure - what an awful idea, a recipe for disaster

    * every device their own ip - um why?

    And then there's the cost of implementing. Just as a simple example you can currently ssh or rdp to servers without needing dns to be working because you remember those critical ips and can type them in quickly. Try doing that in the ipv6 world. So you need new infrastructure to manage your addresses - that's not theoretically a difficult thing to do, but just one more reason to put off a non-urgent (to the people with ip4 addresses) change which gives no upgrade advantage.

    There may be advantages to ISPs and network managers, I don't know, but they obviously aren't big enough that ISPs are pushing this change to consumers.

    In theory, there's no difference between theory and practice; in practice there is.

    Yes, it's in the interest of society. They don't need them, just take them and give it to others....

    What? That's not fair? Well of COURSE it's fair and as long as I am the person to implement it everything will be OK. Anybody who disagrees with this is OBVIOUSLY a nut case as rebalancing the fairness of internet addressing is in the public good and of course I'm only interested in the public good.

    The road to Hell is paved with good intentions. God save me from people who would do good my name.
