UK ISP PlusNet Testing Carrier-Grade NAT Instead of IPv6 445
judgecorp writes "Faced with the shortage of IPv4 addresses and the failure of IPv6 to take off, British ISP PlusNet is testing carrier-grade network address translation CG-NAT, where potentially all the ISP's customers could be sharing one IP address, through a gateway. The move is controversial as it could make some Internet services fail, but PlusNet says it is inevitable, and only a test at this stage."
Regarding the failure of IPv6, these graphs imply otherwise.
