In case you haven’t noticed -which should be a good thing- today is the World IPv6 Day.

On 8 June, 2011, Google, Facebook, Yahoo!, Akamai and Limelight Networks will be amongst some of the major organisations that will offer their content over IPv6 for a 24-hour “test flight”.

Not need to worry about access. IPv4 access will still be available. But you should know that IPv6 is designed to succeed Internet Protocol version 4. The new address space will support 2^128 addresses. To make things clearer, every person on Earth could get a-29-digit number of IPv6 addresses. That’s a lot. Why? Because we are running out of IPv4 addresses.

Taking advantage of this new Internet Protocol version could not only take care of our need for more IP addresses but also lead to great innovation. Imagine a world where you can control every device on your home remotely, let’s say from your mobile phone. Of course you can already do this. But this is something slightly different.

You can test your IPv6 connection on ipv6test.google.com. If you need a more technical take on IPv6 you should read RFC 2460.
