   Current projections place IPv4 address space exhaustion somewhere in late 2011, and while technologies such as Network Address Translation (NAT) can offer temporary respite, they complicate the Internet's architecture, pose barriers to the development of new applications, and run contrary to network openness principles.

.... Google search is also available over IPv6 at ipv6.google.com (you'll need an IPv6 connection to view it). While IPv4 provides about four billion IP addresses — not enough to assign one to every one of Earth's more than six billion inhabitants — IPv6 provides enough address space to assign almost three billion networks to every person on the planet. We hope that by allowing every computer and mobile device on the network to talk to each other directly — an idea known as the "end-to-end principle" that was crucial to the original design of the Internet — IPv6 will allow the continued growth of the Internet and enable new applications yet to be invented.

It appears that some savvy techies already knew this

You are right Tony

**** Warning ****
There is a serious potential hazard with adopting ipv6.
Because its address space is so large, it can be used for wide spread tracking and spying. This is similar to embedding a tracking code in a url, but much harder to detect and thus much harder to avoid.

George R: not really.

Although everyone and their refrigerator can have a unique IPv6 address, it's also true that everyone can have many IPv6 addresses. You could use a different one every day if you wanted to avoid tracking.

Also, there's nothing to stop you using technologies such as NAT with IPv6, in which case your IPv6 address would be no more trackable than your IPv4 address. But then you also lose many of the other advantages of IPv6.

IPv6 cannot be sustained as the ""end-to-end principle" without net neutrality. This is of prime importance. Having sufficient Address space can't stop that problem. Carriers will leverage the Priority and Flow Label fields within the IP header. What we might see are islands of IPV6's within the cloud.

As for tracking, its possible, even f you change you V6 address every day!!

I am not concerned about my IP being tracked.
I am concerned about being tracked by a unique IP to which I respond.
