Our Goal

The Task Force aims to examine the impact of IPv4 address exhaustion from the varying standpoints of the multiple players invloved in the provision of network systems (infrastructure providers, equipment vendors, system integrators, service providers, etc.), imparting the need for an industry-wide recognition of issues and consideration of countermeasures. WIthin this process we would like to continually emphasize the importance of the open sharing of information.
As a collaboration of Telecommunications and Internet-related Associations, the Task Force hopes to integrate the resources of our various member communities, actively working toward the smooth continuity of Internet-based business throughout the process of and following the exhaustion of IPv4 addresses.
