Communications technologies are evolving rapidly. This pace of evolution, while slowed somewhat by economic circumstances, still moves forward at a dramatic pace. This is indicative to the fact that while the ‘bubble’ of the 1990’s is past, society and business as a whole has arrived to the point where communications technologies and their evolution are a requirement for proper and timely interaction with the human environment.
This has profound impact on a number of foundations upon which the premise of these technologies rest. One of the key issues is that of the Internet Protocol, commonly referred to simply as ‘IP’. The current widely accepted version of IP is version 4. The protocol, referred to as IPv4 has served as the foundation to the current Internet since its practical inception in the public arena. As the success of the Internet attests, IPv4 has performed its job well and has provided the evolutionary scope to adapt over the twenty years that has transpired. Like all technologies though IPv4 is reaching the point where further evolution will become difficult and cumbersome if not impossible. As a result, IPv6 was created as a next generation evolution to the IP protocol to address these issues.
