The Internet addressing system conceived in 1977 at the U.S. Department of Defense by Vint Cerf, today chief Internet evangelist at Google, used 32-bit Internet Protocol (IP) addresses to connect people to people, providing more than 4.3 billion unique hosts for trusted user accounts. As the Internet began to be dominated by M2M connections, a revised, 128-bit scheme (IPv6) was adopted to allow for 18 billion billion hosts, accommodating more than 300 trillion trillion trillion secure devices.
Now there is more than enough address space, along with Internet Protocol Security (IPsec), to accommodate the universe of cloud-ready devices that IBM Corp. last year predicted would surpass 1 trillion nodes by 2015.
