Your IPv6 Client Needs to Communicate w/your IPV4 Server Now!

It’s quickly becoming a reality.  Every organization must eventually adopt IPv6 at some point in time. For many, the time is now because IPv4 address space has been depleted.

Consequently, IPv4 depletion forces rapid adoption to IPv6 because an IPv4 client simply can’t directly communicate with an IPv6 server.

  1. The end-to-end communication must have both ends talking the same language
    ( IPv4 or IPv6)
  2. More and more ‘things’ will require integration with IPv6.   Each entity requires an IP ‘address’ to identify itself.  IPv6 is the only way to provide this at the current time.
  3. All the existing entities (running on IPv4) should be able to talk to the newly connected online entities.


This is why it is so critical for older clients and servers to communicate with newer servers and clients respectively. All these clients and servers are likely running separate IP versions.  It’s virtually impossible for so many clients and servers to transition to IPv6 at the same time under the best of circumstances.

In fact, the hurdles of moving to IPv6 are more than the original architects of IPv6 imagined. The cost factor, application level changes to accommodate IPv6, availability to all infrastructure gears supporting IPv6, moving from IPv4 to IPv6 network without any disruption to services are some of the hurdles.


So, the question of how organizations handle IPv6 transitioning becomes very crucial.

Technology has offered various solutions, or more appropriately intermediary steps, for this transition. These steps/techniques have enabled an IPv4 client to communicate with an IPv6 server by doing “what I call, “some magic’ in-between.” They have enabled IPv6 client to communicate with IPv4 server. The list of techniques is very big and each organization chooses one or some of them based on their preference, strategic planning etc.

With so many complexities in mind, look for me to provide information about the various techniques necessary to enable your systems in the near future.  As, I hope to provide you with the information you need to complete a successful conversion process.  One by one, allow me to cover each technique and describe how each can best be implemented.  And, oh yes.  Let’s include NetScaler as well.
