摘要：In the rapidly evolving concept of IPv4 addressing space, it has become a high priority for serviceproviders, enterprises, IP appliance manufacturers, application developers and governments to initiate their ownimplementations of IPv6. Seamless migration from IPv4 to IPv6 is difficult to achieve. Therefore, several mechanismsare required to ensure a smooth, step-like and independent change of IPV6. Not only is the transition, IPv6 integrationis also required in existing networks. The solutions (or mechanisms) can be divided into three categories: Tunneling,Dual Stack and Translation. Many people think that NAT is a better approach, but Tunneling is a preferred and moreversatile way of deploying IPv6 in existing IPv4 environments. IPv6 can be enabled where IPv4 is enabled along withthe associated features required to make IPv6 routable, highly available and secure. In some cases, IPv6 is not enabledon a specific interface or device because of the presence of legacy applications or hosts for which IPv6 is not supported.Conversely, you can enable IPv6 on interfaces and devices for which IPv4 support is no longer needed. The MobileInternet Protocol (IP) allows the routing of IP packets on the Internet regardless of location. A tunnel is a virtual tubefor the movement of data packets between its input and the endpoint. Encapsulation is the mechanism of wrapping theheader and data of a packet and embedding it in the data section of the next packet. The biggest challenge was theincreasing number of users with a variety of services and mobile devices in a wireless communication when movingfrom a home area network to a foreign network. In such a situation, the mobile node also interacts with the homenetwork.
