To answer that question first we need to look at the significance the current IP layer has in our day to day lives. Beyond that we need to, for lack of better words, “follow the money” that these IP based applications, services and infrastructure support. Stability of IP based communication is something we may take for granted but what would happen if that stable IPv4 layer was replaced with a not so stable upgrade? My home network connection goes out, kind of irritating but in the big picture I will probably forget it… the first time. Service Providers realize that if they cannot provide you with a stable service you may not be a happy customer, which may open the door for you to look elsewhere. Beyond that, the loss of IP based communication in many industries is seen as a loss of hundreds of thousands of dollars per second both in revenue generation and loss of opportunity. The point is, much of the world economy relies on a stable network at all times.
