IPv6: issues and solution for next millennium of internet

IPv6 is coming, whether we like it or not. It isn't a matter of new features or "killer applications," although those may come with time. Rather, it is the rapid depletion of the remaining IPv4 addresses that is leaving IPv6 as the only feasible alternative for the continued growth of networks beyond the next few years. Governments and service providers in many regions of the world have been cognizant of this fact for a long time, and are currently in various stages of planning for IPv6 deployment in their networks. The IPv6 was developed to replace and improve the existing Internet Protocol (IP), the IPv4 in many ways. Among the improved areas are addressing space, routing efficiency, header format, auto-configuration, Quality-of-Service (QoS), security and mobility. This paper investigates the IPv6 deployment issues' in India and provides potential solution for the same.
