IPv6The Internet address space available under the current protocol, IPv4, will run out real soon, 2011, and the only long term solution is to transition to IPv6 which has sufficient address capacity to give every grain of sand on the planet its own unique Internet address, or something like that.
Only 16% of the total IPv4 address space remained unallocated in early 2008, this situation is critical for the future of the Internet economy because all new users connecting to the Internet, and all businesses that require IP addresses for their growth, will be affected by the change from the current status of ready availability of unallocated IPv4 addresses.
