OREANDA-NEWS. Fujitsu Limited, Fujitsu Computer Technologies Limited, the National Institute of Information and Communications Technology (NICT), and the Japan Advanced Institute of Science and Technology (JAIST) announced that they recently conducted a successful large-scale test of a solution technology that will enable IPv4 addresses to be assigned (shared) to different devices at datacenters configured with IPv6 networks.

The test succeeded at running SA46T-AS - a technology developed by Fujitsu for sharing IPv4 addresses on IPv6 networks, announced June 12, 2012 - using StarBED(2), NICT's large-scale network testbed. For the first time the test confirmed automatic large-scale operations, with no need for manual operation or individual settings, even with virtual servers running SA46T-AS on StarBED.

The success of the test on a large-scale network demonstrated the practicality of SA46T-AS. This, in turn, will make it possible for multiple devices that employ IPv4 addresses - which are still in widespread use despite the fact that IPv4 address space is becoming scarce - to share a single IPv4 address, rather than each needing to be assigned their own separate address. As a result, it will be possible to continue and even augment the use of IPv4.

Details of this technology will be presented at the 6th Internet and Operations Technology Symposium (IOTS2013), to be held from December 12-13 at Hiroshima University.
