1,273rd day from now, there will be a major web chaos. The Internet will run out of IP addresses.
More than 85 % of the available IP addresses have already been allocated and the rest will run out by 2011, according to a prediction by the Organisation for Economic Cooperation and Development (OECD).
Essentially, IP address is a unique 32-bit number that identifies the location of your computer
on a network. The current IPV4’s infrastructure was laid way back in early 80s keeping 4 billion addresses in mind. Things have multiplied since then and now we are left with only few machines!
What about IPV6?
IPv6 supports 2128 (about 3.4×1038) addresses, or approximately 5×1028 addresses for each of the roughly 6.5 billion (6.5×109) people alive today. In a different perspective, this is 252 addresses for every star in the known universe – more than ten billion billion billion times as many addresses as IPv4 supported.[source]
The challenge with IPV6 is the backward (in)compatibility of devices as well as lack of widespread adoption – neither ISPs nor manufacturers are investing enough in the infrastructure.
Another prediction: Internet can overshoot the supply by 2010 (thanks to rich media sites).
