Internet father in growth warning

We are onto our last 4 billion addresses and estimates highlight that these will run out in spring 2011 with the continued usage of IPv4. Without any new addresses, we will not be able to add any new people and the problem of trying to sell a telephone without a telephone number will set in.

Although the technical foundations for IPv6, the internet protocol format which would allow for trillions of new unique IP addresses, have been ready for many years, only a small number of business websites, routing equipment and internet service providers use it. There is a lack of compatibility between IPv6 and IPv4. As such, there could be connection problems between mature markets and other new markets.
