Abstracts: IPv6 is the next generation protocol for the Internet, designed to support continued Internet growth in number of users and functionality. The current version, IPv4 was developed in the 1970’s and provides the basis for today’s Internet interoperability. Ipv4 suffers some limitations that may be inhibitors to growth of Internet, and use of the Internet as the global networking solution. Requirements for more address space, simpler address design and handling at the IP layer, better quality of service support, grater security, and an increasing no of media types and internet-capable devices have all contributed to drive the development of IPv6. IPv6 is a new version of IP which is designed to be an evolutionary step from IPv4. IPv6 is designed to run well on high performance networks and at the same time still be efficient for low bandwidth networks. In addition it provides a platform for new internet functionality that will be required in near future. IPv6 is designed to solve many of the problems of IPv4 such as address depletion, security, auto-configuration, research and extensibility. Its use will expand the capabilities of the Internet and enable a variety of valuable and exciting scenarios, including peer-to-peer and mobile applications. IPv6 includes a transition mechanism which is designed to allow users to adopt and deploy IPv6 in a highly diffuse manner and to provide direct interoperability between IPv4 to IPv6 hosts.The IPv6 transition allows the user to upgrade their hosts to IPv6, and the network operators to deploy IPv6 in Routers, with very little co-Ordination between the two.
