In these days of Internet addresses will run out. In the Internet every object is identified by an IP address, which in the current version is composed of 32 bits and is therefore able to identify 4 billion different objects. Too bad that an object is for example my desktop, my laptop, my cell phone. So often I find myself using more IP addresses for various purposes. Too bad also that the number of inhabitants of our planet is nearly 7 billion, so it is not possible for all of us have at least its own address. There are technical solutions that until now have managed to enable the development of Internet in this scenario of limited resources. In particular, a technique, the NAT has allowed multiple users browsing with the same address through an additional port-based service differentiation. This technique has saved addresses, but the current need for mobility, the use of multiple simultaneous accesses by many of us, the enormous increase in service required by the emerging realities, the need to identify and control ever greater amounts of objects, the convergence of all telecommunications infrastructure to the Internet, this has meant that addresses today are really on the brink of exhaustion. What next? And how? Some say that exhaustion will be today. Other within a few months. All confirm that the period is still this. Do not have multiple addresses such means he can no longer turn on new servers, they can no longer create new services. The solution exists and is called IPv6, or Internet address of the new generation. With 128-bit address space becomes available, enormous, enough for today, tomorrow and probably forever. But the question is whether we're ready. They are ready our telecommunications operators? They are ready our home router? They are ready our operating systems? Our applications are ready? What investments should I do? An attractive challenge, we'll see what happens over the next few days.
