Hurricane Electric’s Martin Levy was interviewed for a recent article on IPv6 for The Economist. From the article:
Two raised to the 128th power is an enormous number: roughly 340 billion billion billion billion—or, as Martin Levy of Hurricane Electric likes to say, “more than four quadrillion addresses for every star in the observable universe”. That will come in handy when the “internet of things” becomes a reality. Already, some 2 billion people have access to the internet, many of whom own multiple devices. The use of Wi-Fi base-stations and routers that allow sharing of a single IP address has put off the day of reckoning for a while. But add all the televisions, phones, cars and household appliances that are currently being given internet access—plus, eventually, every book, pill case and item of inventory as well—and the need for IPv6 is clear.
