Internet Protocol 6 - Federal Government in Early Stages of Transition and Key Challenges Remain

GuidanceGovernment Accountability Office (GAO)General Information

Why GAO Did This Study

The Internet protocol (IP) provides the addressing mechanism that defines how and where information such as text, voice, music, and video move across interconnected networks. IP version 4 (IPv4), which is widely used today, may not be able to accommodate the increasing number of global users and devices that are connecting to the Internet. As a result, Internet version 6 (IPv6) was developed to increase the amount of available address space. In August 2005, the Office of Management and Budget (OMB) issued a memorandum specifying activities and time frames for federal agencies to transition to IPv6. GAO was asked to determine (1) the status of federal agencies' efforts to transition to IPv6; (2) what emerging applications are being planned or implemented that take advantage of IPv6 features; and (3) key challenges industry and government agencies face as they transition to the new protocol.
