The emergence of IPv6, providing the world with an exponentially larger number of available IP addresses, is essential to the continued growth of the Internet and development of new applications leveraging mobile Internet connectivity. Although the information technology (IT) community has come up with workarounds for this shortage in the IPv4 environment, IPv6 is the true long-term solution to this problem.
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
