Overview: The original framers of ARPAnet did not foresee the growth of what is now known as the Internet, or that the IPv4 address structure would fall short of the addresses needed, or all the new devices that would need IP addressing. Consequently, the IPv4 addresses are being exhausted. IPv6 satisfies the increasingly complex requirements of hierarchical addressing that IPv4 does not provide. One key benefit is that IPv6 can re-create end-to-end communications without the need for NAT--a requirement for a new generation of shared-experience and real-time applications. This white paper explains why a transition from IPv4 to IPv6 can be beneficial.
