IPv4 is being replaced with the new Internet protocol IPv6. The current protocol IPv4 having problems such as impending exhaustion of its address space, configuration and complexities due to rapid growth of the Internet and emerging new technologies. To eliminate the shortcomings of IPv4 and deliver new features and services, Internet Engineering Task Force (IETF) developed the next generation IP called IPv6. IPv6 is designed to replace the 35-year-old IPv4 protocol and some transition technologies were developed for the transition from IPv4 to IPv6. A smooth transition mechanism is required during the time of migration from IPv4 to IPv6 networks. This paper describes how this transition is possible, we proposed three different methods for migration to IPv6 from the existing network namely Tunneling, Dual Stack and Translation and we brief tunneling mechanism for implementation an IPv6 network over IPv4. This papers aims to supplement the design for co-existence of IPv4 and IPv6 network using manually configured tunneling, a strong transition tool.
