"I am following the issue of the decreasing availability of network addresses, and I am concerned about this. When network technology was first developed, no one could have anticipated how broadly it would be adapted and how many addresses would be required across the globe. I believe that we as an industry can address this in several ways. The first is to ensure that all the currently allocated addresses are in use, and if not, to reallocate them for new users. I also believe we can work on technology that would enable the existing addresses to be used by multiple users with techniques such as machine code and multiplexing algorithms. I understand that Cisco, along with some of the international network standards organizations, is already working on these types of solutions."
