During the time of migration from Internet Protocol Version4 to Internet Protocol Version6 network, a various number of transitions mechanism have been proposed to ensure smooth, stepwise and independent changeover. IPv6 was proposed by IETF (Internet Engineering Task force) as a replacement of IPv4 protocol. When IPv6 was applied in cellular network, need of some improved Protocols was felt in order to support the mobility and Quality Of Service of a node.IPv6 Tunneling is a process where an encapsulation technique is fairly simple in which outer IP header is added before the original IP header, between them any other headers for the path, such as security headers specific to the tunnel configuration. The outer IP header source and destination identify the “end points” of the tunnel. Tunneling has two types i.e. automatic and configured. Tunneling is applied in four way i.e. Host-to-Host, Host-to-Router, Router-to-Router, Router-to-Host. Analyze the Automatic and Configured Tunneling in all the four way of Tunneling. Automatic tunnel is not point-to-point; it is point-to-multipoint. Configured tunnel is Simple point-to-point tunnels that can be used within a site or between sites.
