Internet Protocol Version 6: Federal Agencies Need to Plan for Transition and Manage Security Risks;Report to the Congress

摘要

The Internet protocol (IP) provide the addressing mechanism that defines how and where information such as text, voice, and video move across interconnected networks. Internet protocol 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, IP version 6 (IPv6) was developed to increase the amount of available IP address space. GAO was asked to (1) describe the key characteristics of IPv6$ (2) identify the key planning considerations for federal agencies in transitioning to IPv6$ and (3) determine the progress made by the Department of Defense (DOD) and other major agencies to transition to IPv6.
