      internet is about freedom? what the fuck bullshit are you talking?

      did "the owner of the internet" have a press release I missed on "what it's all about"?

      as far as I can tell it's primarily about information and communication, and more recently secondary aims like commerce.

      should you have the "freedom" the post information or conduct communications that would be illegal in another medium? no, of course not.

    With all of the advances going on in Asia with regards to IPv6, is this going to result in a large split in the internet as more sites appear on possibly ipv6-only servers?

    Most of Europe and the US is seriously falling behind with IPv6, and there's still very little incentive to improve this - chicken and egg indeed. My employer is a large telecom with 1 million ADSL subscribers, but has no concrete plans to roll out IPv6 still, as they see no pressing business need for it. But I fear this will isolate us from the huge economy in asia.

    There will soon be a time where there will be a lot if great content on servers that are only IPv6 capable, and these may slowly develop into separate 'internets'. What can be done for the rest of the world (ie, Europe and the US) to catch up on this? We may end up being left behind as asia powers ahead with technology.

    But then again, Asia is where most of the newer tech goodies come from, so hopefully we will start seeing more everyday appliances supporting IPv6 natively, which could be the boost we need for full v6 support in the infrastructure.

      Oops forgot to login for my comment. You could always vote with your credit card and change to an ISP which does support ipv6. They do exist. The ISP I use supports ipv6 (it's in the UK though so no use to most people here I suppose). The point is that ISPs supporting ipv6 do exist and is a unique selling point for those ISPs. It's of limited use at the moment but I suspect soon enough it will be become more use and those few isps and their customers who do support it now will have a great headstart,
    • Well, there are already several 6-to-4 and 4-to-6 gateway sites. This one is one example [sixxs.net]. If there was a site that was only accessable through IPv6 you could use a service like that to access it over any IPv4 host.

      Also, if you have an IPv6-capable host you can use a tunnel broker (such as Hurricane Electric's free service [tunnelbroker.net]) to achieve connectivity to IPv6 sites over IPv4.

      So you really don't need an IPv6-capable ISP to access IPv6 hosts, although it's cleaner that way of course.

      From wikipedia [wikipedia.org]:

      ". IPv6 is intended to replace the previous standard, IPv4, which only supports up to about 4 billion (4 × 109) addresses, whereas IPv6 supports up to about 3.4 × 1038 (3.4 dodecillion) addresses. This is the equivalent of 4.3 × 1020 addresses per inch (6.7 × 1017 addresses/mm) of the Earth's surface."

      It should hold for a little while.

      It's enough addresses for many trillions of addresses to be assigned to every human being on the planet.

      The earth is about 4.5 billion years old.

    From the article: One big benefit of the IPv6 is to solve the problem of shortage of IP addresses. In the current Internet based on IPv4 technology, the United States controls 74 per cent of 4 billion IP addresses, while the amount that China has is only equal to a campus of the University of California, despite its 80 million Internet users.

    Although people think that with NAT all IPv4 related problems could be solved here we see a very good reason why the rest of the world could use IPv6. Most of the IPv4 ranges are in the US. The rest of the world just has to get by with whatever is left (Big companies gobbling up entire classes of IP ranges which they never really use should be obliged to gives those ranges back so others can use them).

    Would this step be beneficial to the transition to IPv6? With the advent of the internet in other countries then the western world it could well be that things need to be sped up so that we will not see different internets. Has anyone done some real research on this subject? I know i keep hearing that with NAT and similar technologies IPv6 might not be necessary but is that really so given the rise of internet usage in Asia and other countries?
    • NAT doesn't solve all IPv4 related problems. It makes is possible that your second computer doesn't need another IP address and for that we don't really need IPv6.

      But IPv6 solves a bigger problem, namely that routing tables of the core internet routers (those which don't have a default route) are really getting too big with IPv4. With IPv6 the number of routes can be an order of mangitude smaller.
