The unique numbers, which are known as Internet protocol addresses, help identify the world's networked devices.
An IP address uses four numbers from 0 to 255 to distinguish one computer from another. As an example, computers around the world can recognize the IP address 18.104.22.168 as a server for fairfax.com.au, which publishes this newspaper online.
IPv6 has a vastly larger address space than IPv4. This results from the use of a 128-bit address, whereas IPv4 uses only 32 bits. The new address space thus supports 2128 (about 3.4×1038) addresses
While personal computers have been capable of understanding IPv6 since Windows XP and Apple OS X, Huston says only about 5 percent of devices are configured to do so. Among web servers, the figure is less than 1 per cent.
Internode is one of the few Internet service providers that offers an IPv6 service. Telstra is among the many that do not. Tens of millions of mobile phones are on an IPv4 network only.
Lacking that, consumers whose computers are not configured to use IPv6 won't see new websites. Likewise, iPhones, which don't understand IPv6, will be limited to the "old" Internet.

Remember that little page/alert box that someone made that said "You have reached the end of the Internet, there is nothing more to see" or something similar to that any way.

Fake, fake, fake, did I mention FAKE? This is an old time stupid e-mail hoax. IP addresses will never 'run out' and anyone with any understanding would know better. Why even post such garbage? If you're going to post links, then please at least use reliable, trust worthy news. Not those like india times and what ever else that are known for posting nonsense.

Internet Service Providers urgently need to roll out the next generation of net addresses for online devices, internet pioneer Vint Cerf has said.
Every device that goes online is allocated a unique IP address but the pool of numbers is finite and due to run out around 2010.
A new system, called IPv6, has been awaiting roll out for 10 years.
The "father of the internet" has warned that the web is running out of addresses and users need to act now to change to a new system.
Vint Cerf, the man who helped invent the system and one of the world's leading computer scientists, said that the web does not have enough unique codes that allow computers to communicate with each other.
The new address space thus supports 2128 (about 3.4×1038) addresses.

If the ISP's serve IPv6 to their customers, IPv4 addressing won't be a problem for the backbone as the ISP will NAT, similarly to how home routers NAT public IP addresses to private- 10.x.x.x; 192.168.x.x, 169.254.x.x; 172.16.x.x-172.31.x.x. So, if an iPhone or other device has a "private" IPv4 address and if AT&T has their stuff together, the phone-to-Internet gateways will translate properly from public IPv4/v6 as necessary.
I'm not saying addressing is not going to be a problem but fear-mongering is one. Even if it gets to where the backbone uses only IPv6, that will free up A LOT OF IPv4 addresses for ISP usage.
