    So your plain IPv4 name lookup is very slow: 4 seconds!

    Your wget is also very slow (22 seconds). Theoretically that might be caused my IPv6, but I don't think so.
    Easy final test "time wget www.nu.nl" (which is IPv4 only).

    Conclusion: you have a very slow systems and/or Internet connection. That's why the RIPE site is showing red logo's. I has nothing to do with IPv6.

    Getting IPv6 on your system is easy: "sudo apt-get install miredo". But at the current state of your system/connection I think you have more urgent things to do: make your system and/or Internet connection faster. I can only understand your slowness if:
    - you're on dialup Internet, and/or
    - you have minimum requirements system (like < 512 MB RAM)
    - your system is overloaded
    - your Internet connection is heavily used, for example bittorrent using the full upstream connection

    So if you want to solve that, start new thread.

    Miredo installed. And after that:

    http://ipv6eyechart.ripe.net



    http://ipv6.google.com



    http://test-ipv6.com/




    http://ipv6test.google.com



    Although everything is a little slower now. As for the speed of my connection, it is max 3.1 Mbps and at the time of this writing it is 1.2 Mbps. Is this slow?

    If you see the video (http://www.mediafire.com/download.php?dd09cx96khpr1px), you will notice that everything has just become more worse after Teredo. Many connections are failing even after a reload.

    Good: your IPv6 works. Easy, isn't it?

    3.1 and 1.2 Mbps are not explanations for your slow Internet connection. As a said: open a new thread with subject "Slow Internet". It's not IPv6 related.

    Re: Problems with IPv6

    But I am still confused, why should the problem occur only in Ubuntu? It doesn't occur in Windows. And Google tells me that I still ain't ready on Ubuntu. Before miredo, I got many red logos on http://ipv6eyechart.ripe.com/ and that would be resolved (the Akamai dual test was the only one that failed) if I reloaded the page. Now, 8-17 tests fail even after reloading.

    Re: Problems with IPv6

    My IP doesn't support IPv6 yet but using either a tunnel broker or miredo in 10.10 all test indicate good to go here.
    BTW quit quoting those pics every page.....not necessary and not doing so can prevent horizontal scrolling carpal tunnel syndrome.

    Re: Problems with IPv6

    Windows XP doesn't support IPv6 by default (run ipconfig /all; no ipv6 addresses will be visible.) In contrast, Ubuntu - like windows 7 - does have IPv6 on by default.

    If you check your test-ipv6.com results, you'll see that the two OS's are actually seeing the same upstream connectivity. The pie chart differences appear to be due to DNS resolution timing, not to differences in IPv4 versus IPv6 transport.

    Ironically, while you don't appear to have native IPv6, Tata is one of the world IPv6 day participants.

    If you want to experiment with IPv6 using a tunneling technology, the simplest would be Teredo; do sudo apt-get install miredo and it will be live. However, native IPv4 connections will rightly be preferred to tunneled IPv6, so it won't be used except with IPv6-only sites, of which there are very few at present.

    For more serious IPv6 R&D, I prefer setting up a point to point link with a tunnel broker. In the USA, the 3 main free choices are www.tunnelbroker.net, www.sixxs.net, or the "freenet6" service from gogo6.com. Setup details vary slightly. If your ISP offers something, that would be better than any of the free services.

    Re: Problems with IPv6

    here's my eyechart FTW

    6to4 seems not doing badly (those circles should be red X's i think)
    at least comparing to teredo as i see

    to bad it is going deprecated , 6to4

    Re: Problems with IPv6

    Well... if your ISP doesn't support it, then you can't do IPv6.
    Also, if that's the case, there is nothing to worry about, you will just use IPv4.

    No, you can do IPv6 whether your ISP supports it or not. The only reason you could not do it is if the ISP actively chooses to block protocol 41 packets.
