The depletion of IPv4 addresses is an immediate concern facing service providers and large network operators of all types. In the very near term, service providers will need strategies and tools to help them deal with the depletion of IPv4 addresses while starting their eployment of IPv6. IPv6 and IPv4 are not interoperable out of the box, and this causes certain technical challenges. Moving abruptly to an IPv6-only network would put service providers at a competitive disadvantage for two reasons. First, there is very little content available on IPv6. Second, there are many devices and applications today that can only work in an IPv4 environment.
The future of the Internet is going to certainly include both IPv6 and some form of “natted” IPv4 with technologies such as Carrier-Grade NAT (CGN AT) for many years.
Our consultants have been involved with some of the largest carriers in Europe to determine their IPv6 deployment strategy. We have expertise in the various techology alternatives related to IPv4 and IPv6 integration, such as CGNAT, NAT44, Dual Stack.
