Internet Protocol version 6 (IPv6) : Trouble connecting - Web Search Help

"Ready for the future of the Internet?

Looks like your connection isn’t ready for IPv6.

This may be due to problems with your home router, operating system, or ISP. For help resolving these issues, visit the Google Help Center.

If you don’t fix your connection, you may experience severe problems connecting to Google and other sites on World IPv6 Day, June 8.

Learn more about IPv6, or read about World IPv6 Day."

I just got this message today when I went to do a search on Google.com, after 6PM! And I've been on the Internet Every Day All Day... forever! Yes, I did know about the coming of IPv6 for a while now. But not this, "World IPv6 Day On 8 June, 2011". I have my older Router at the Gateway of my Internet Connection and it looks like it is only IPv4. I have a new Router that I got just a month ago, setup behind it. It was just easier to setup my Port Forwarding that way and the older Router was already setup the way I needed it to be. I looked at my new Routers Manual and I don't see anything in it about IPv6. Who would have thought that a Brand New Router Wouldn't Support IPv6!:O I guess I will have to Rewire things to make sure though. I tried the Suggestions for making an "/etc/gai.conf" file. But that did nothing for me. I set my IPv6 settings in my Fedora 14 to Automatic and will do a Reboot to see if that helps or hurts. Usually when I try this, I loose my Internet Connection All Together... Yep, that's what it did. No Connection after a Reboot. So I set IPv6 back to "Ignore". That's the Default. I figured changing things in my Computer wouldn't help, since my Gateway is a Router. Well, actually my Cable Modem is my Internet Gateway and then the Router is my Gateway for my Home Network. I know just enough about Networking, to be dangerous! Very Dangerous!;) Guess I'll try putting the new Router ahead of the older one in the Daisy Chain, Tomorrow. I'm done for today...

Test your IPv6 connection to see if your computer and connection are ready for IPv6.

What is IPv6?

The Internet Protocol (IP) is the language that computers use to communicate with each other on the Internet; it works much like phone numbers, which let us connect one telephone to another.

IPv6 is the new version of the Internet Protocol. The addresses used by the current version of the Internet Protocol, IPv4, are nearly all used. At Google, we believe that IPv6 is essential to the continued health and openness of the Internet – and that by allowing all devices on a network to talk to each other directly, IPv6 will enable innovation and allow the Internet to continue to grow.

World IPv6 Day

Most websites today use only IPv4. But on June 8, 2011 - World IPv6 Day New window         icon - major web companies, including Google, Facebook, Yahoo!, and Bing, will enable IPv6 on their main websites for 24 hours. IPv6 will be enabled in addition to IPv4, so if you don’t have IPv6, don’t worry - you will simply use IPv4 as usual.

IPv6 connectivity issues

Over 99.9% of users do not have any problems going to IPv6-enabled websites. However, in rare cases, users may have IPv6 enabled, but not working properly. This may cause delays and connection problems when visiting Google and other participating websites on June 8.

IPv6 connectivity problems are usually caused by misconfigured or misbehaving home network equipment (e.g., home routers), bugs in operating systems, or issues in ISP networks. In many cases, the problem can only be solved by upgrading or replacing home routers and by upgrading operating systems, or if the ISP fixes it. However, it is possible to work around the problem by using IPv4.

If you experience delays connecting to IPv6-enabled websites, you can work around the problem using one of the following:

  • Use an IPv4-only website, if one is available. For example, you can access Google at ipv4.google.com instead of www.google.com.
  • Upgrade to the latest version of your browser. Older versions of many browsers have known bugs with IPv6, and later versions may incorporate workarounds for IPv6 connectivity-related issues in operating systems, routers, and ISP’s.
  • Install a browser that includes workarounds for IPv6 connectivity problems, such as Google Chrome.

If you are still experiencing connectivity issues, here are some additional suggestions for common operating systems:

Windows 7 / Windows Vista

Try one of the following options:

  • Disable IPv6 tunnel interfaces. Tunnel interfaces are less reliable than native IPv4 or IPv6 connectivity. You can do this by downloading Microsoft Fix it 50412.
  • Configure your computer to use IPv4 instead of IPv6. You can do this by downloading Microsoft Fix it 50410.

    scopev4 ::ffff:127.0.0.0/104 2
    scopev4 ::ffff:0.0.0.0/96 14
  • Disable IPv6 by using the following command:
