Federal government agencies should prepare for the future of networking and Internet technology by enabling their networks to support IPv6 addresses and data packets.  There are many considerations when introducing any emerging technology into an organization’s infrastructure.  Therefore, this type of transition should be done methodically and mindfully, with full awareness of the benefits, challenges, and caveats surrounding the technical implementation of IPv6.  This document outlines many of these benefits, challenges, and caveats, and provides Federal government agencies with IPv6 transition “best practices” which can be used to inform agency IPv6 transition planning and the adoption of IPv6 into their IT infrastructure.
