The November 6, 2006 issue of Business Week (www.businessweek.com) includes an article entitled "More Elbow Room on the Net: A pending upgrade will provide an almost limitless number of addresses"
The current standard for IP addresses on the Internet (IP version 4) supports up to 4.3 billion IP addresses (4.3 x 10 to the 9th power). This limit is projected to be reached by 2010.
The new standard for addressing (IP version 6) will support up to 3.4 x 10 to the 38th power addresses. IP version 6 comes with encryption and authenication built in.
The Department of Defense and other government agencies expect to spent tens of billions of dollars over the next ten years to upgrade its telephone and computer systems.
"Federal purchasing officials have already said they plan to require all civilian and defense agencies to upgrade their key network equipment to IPv6 within 20 months."
