Nokia Views on IPv6 Transition
The transition to Internet Protocol version 6 (IPv6) is no longer debatable. An increasing number of global internet users and the impending exhaustion of IPv4 addresses managed by the five regional internet registries have increased the pace of transition to IPv6. These registries now predict the timeframe for IPv4 address exhaustion will be late 2011 to early 2012. Mobile network operators, ISPs, network equipment and device vendors, and standards bodies are all actively addressing the transition to IPv6. To ensure the growth trajectory of internet users and applications, a smooth transition to IPv6 is necessary, along with maintaining backwards compatibility with the legacy of IPv4.
