the onus is on you to support that point with evidence I'm not claiming to be an absolute authority on these matters, but merely trying to breed some discussion around the topic. I don't think it's a clear cut case. Most of the problems NAT-unfriendly technologies were supposed to solve have instead been solved by brute force My argument is that over time the brute force required may possibly exceed the work of an actual migration away from IPv4 to something better. The rest of your comment just ignores my argument, which is that individuals don't need routable IP addresses for the Internet to work. In that case, my bad. And this is certainly true for large parts of the internet. If this remains true with the evolution of VoIP, SIP and other unified, global communication protocols taking over for traditional telephony, is probably another matter. as long as the next YouTube can get reachable servers online, what do I care whether my iPencil has a 1918 address? If routable IPs become such a scarcity only rich people can afford it, expect to see internet creativity drop significantly. Part of what makes internet great today is that anyone can contribute and put something online if they want to. Sorry if I can't get all worked up over whether my phone can talk to your phone over direct BitTorrent. That's obviously an extreme, but on the other extreme, if nobody except commercial entities can afford routable IPs, technologies like BitTorrent will die because there will be no connectible peers.

The underclass can't get IP addresses today. Hust because we make hundreds of billions of numbers available tomorrow, doesn't mean those people will be routable for fractions of a cent. There are plenty of logistical problems (RIB size, portability) besides the artificial "scarcity" of IP addresses that retard universal fixed addressing. The rest of your argument just seems like hand-waving. What fraction of "creativity" on the Internet depends on end-station addressing? Web applications don't care what number your laptop claims, and neither does email or IM. If addressing is hurting creativity, it's because you're being creative at the wrong layer of the stack.

  Just because we make hundreds of billions of numbers available tomorrow Actually its more like 4 billion billion billion billion IPs. There are plenty of logistical problems (RIB size, portability) besides the artificial "scarcity" of IP addresses that retard universal fixed addressing. This is indeed true. If you want a small RIB size you need hierarchial address assignment. If you want portability, you need to break hierarchial address assignment. That being said, if portability becomes a limited issue, routing doesn't have to be much worse than it is today, where it is pretty much random. What fraction of "creativity" on the Internet depends on end-station addressing? Today I can put up a server on any DSL, have a public IP (and DynDNS if it's dynamic) and I can serve up new stuff to the entire internet without having to pay for hosting. Granted, that is not a business-class solution by any means, but anyone can do it. If you all of a sudden have to use commercial hosting to put something online, you are 100% at their mercy. What they offer, how they offer it, it will have to work on their server-setup unless you are willing to pay premium for a VPS etc etc. You want to develop some new kind of project/service which doesn't run over HTTP or on Apache? It sure must be encouraging to know that 99% of the internet wont be able to run or host your stuff since you are at the hosting provider's mercy and they have no plans deploying untested software. If addressing is hurting creativity, it's because you're being creative at the wrong layer of the stack. I'll assume this comment means you misunderstood what I was thinking about.

    It's 4 zillion IP addresses just like 64 bit address space is 17 billion gigabytes --- meaning, not any time soon. Let's stipulate that we can both do math, OK? Again, the rest of your argument is hand-wavy. Virtual servers cost dollars a month. Virtually everybody uses them. What's the application I've heard of that, it turns out, is served off someone's DSL? You're saying, the best argument you've got for IPv6 is that it means I might be able to start something Posterous out of my home DSL instead of off Slicehost? Here's a news flash: you can't do that today; your DSL ToS forbids it. Maybe fix that problem before demanding that all the world's socket code get ported to a new address format.
