Dept. of Defense IPv6 Interoperabilty Test Begins

securitas writes "The Department of Defense has launched Phase I of its delayed IPv6 interoperability test (mirror) in a six-month project dubbed Moonv6. It is the largest North American IPv6 test ever and its goal is to evaluate IPv6 for 'network-centric military operations.' Phase II was originally scheduled to begin in January 2004 but may be delayed due to the late start of the current test. 'IPv4 addresses are 32 bits long, enough for around 4 billion unique addresses.' In contrast, the IPv6 address length is '128 bits, or 340 billion billion billion billion unique addresses.' Experts hope this will solve a predicted IP address shortage as more devices are created to use the Internet."
