Google Testing on IPv6

I found this notification when I were reading Blogger Help. Google is testing their IPv6 web site. And successfully done, congrats Mr. G :).

IPv6 will be enabled on major sites (Google, Bing, Yahoo!, Facebook etc..) on June 8 2011. Its called World IPv6 Day. Don't worry, they still support old IPv4. If you experience delay when access www.google.com, you may visit http://ipv4.google.com/ instead.

For those who come late...

IP?
Your cellphone identified by its RUIM number, example 0811 1234 567. And your computer identified by its IP number, example 192.168.1.1. Got it?

What is IPv6?
IPv6 stand for Internet Protocol version 6. It is next generation of IPv4 (Internet Protocol version 4). IPv4 is running out, and IPv6 comes to resolve this problem.

IPv6 enabled on windows XP

And how to uninstall, if something went wrong?
Just repeat step above from 1 to 6. Select Microsoft TCP/IP version 6, then click Uninstall, click Close to exit and save change, that's it.

That's easy, should I activate it now?
No :). Remember that you are connected to Internet by your ISP (Internet Service Provider). You must consult to their tech-support, if their network is IPv6 enabled or not. You also should check your network equipment (modem, router, switch), check  if they are IPv6 ready.
