As the IPv4 address pool is rapidly reaching exhaustion, Silvia Hagen, a leading expert on IPv6 and the author of O'Reilly's book, "IPv6 Essentials," stresses that a primary step towards IPv6 address space is not about "transition" but "integration".
IPv4 and IPv6 are going to co-exist for many years to come and so what companies need to do, in the first place, is to look at their IPv4 landscape and identify areas of priority, Hagen said in a recent interview with CircleID. "And also they need to identify spots where it is very complex to integrate IPv6 and make sure they have enough time for planning and integration," she said. "It's about learning to manage our future dual stack network."
Hagen, who is the president of the Swiss IPv6 Council and has recently joined BlueCat Networks' Technical Advisory Board, believes the value of IPv6 is about connectivity and the continuation of the Internet. Countries in Asia such as Japan, South Korea and China, already have a strong head start in IPv6 due to their greater IPv4 depletion rate and so Hagen believes IPv6 integration is simply a matter of remaining accessible to an increasing number of IPv6 users.
So why do so many companies, particularly at the management level, still remain undecided when it comes to IPv6 integration. Hagen finds that reasons mainly fall into two classic categories: Lack of practical understanding about IPv6 and the incorrect assumption that there is no urgent business case for IPv6. Hagen says that IPv6 is a matter of upgrading a critical infrastructure within all organizations and a simple 3 to 5 year analysis makes it very clear that the time to do it is now.
