IP Tunneling and Stateless DHCPv6 Implementation in an Enterprise Network

IPv4 has so many limitations such as limited assignable addresses, complex subnetting structure, and inefficient employment of NAT among others. It is because of these shortcomings of IPv4 that IPv6 protocol was introduced. IPv6 increases efficiency in routing and packet processing, promotes a simplified network configuration, supports new services and adds to the improvement QoS by reducing latency during packet transfer. There is therefore a need to move to the IPv6 platform. However, such a process is not automatic but deliberate and requires dealing with the current complexities of the IPv4 network. Tunneling is one of the common ways of transiting from IPv4 to IPv6 and vice versa. In this paper we simulated an IPv6to4 tunnel using cisco packet tracer and GNS software. It was shown that tunneling is a possibility and an effective step to preserving IPv4 infrastructure investments towards migrating from IPv4 to IPv6
