The work presented in this paper is intended to introduce to both IPv4 and IPv6. This paper is a comprehensive guide to the evaluation of IPv6 from beginning to end and, therefore, it is meant for audiences of varying expertise from beginners to experts who wish to learn about the next generation internet protocol (IPv6), and have a clear unbiased performance overhead of the new internet protocol. As of October 2011, about 3% of domain names and 12% of the networks on the internet have IPv6 protocol support. Since 2009, the DNS can be used in IPv6 as major web sites like Google. IPv6 was first used in a major world event during the 2009 Summer Olympic Games. Finally, modern cellular telephone specifications mandate IPv6 operation and deprecate IPv4 as an optional capability. The paper its main aim is to perform an unbiased empirical performance analysis between the two protocol stacks (IPv4 and IPv6), and how it related to the performance on identical settings. Over the last decade, many fundamental changes have occurred in data communications and network infrastructure that will be shaping the future of IT for years to come. The Internet is now at the core of communications for worldwide economy and individuals. IPv4 is the basic building block of the Internet and has served well, but it has limitations that hinder its growth. The solution is IPv6, which addresses inherent problems of the earlier version. However, due to the increased overhead in IPv6 and its interaction with the operating system that hosts this communication protocol, there may be network performance issues. The overhead between the IPv4 and IPv6 should be directly proportional to the difference in the packet’s header size, however according to our findings, the empirical performance difference between IPv4 and IPv6 are taken into consideration. Here two OSs (W2Kand Linux Ubuntu) are configured with the two versions of IP and empirically evaluated for performance difference. We first examine the performance of IPv4 and IPv6 independently. This is a necessary and crucial step for IPv6’s success since clear performance limitations and advantages should be well defined and agreed upon in advance. Here performance related metrics throughput is empirically measured on P2P test-bed implementation. The results show that network performance depends not only on IP version and traffic type, but also on the choice of the OS. Our empirical evaluation proved that IPv6 is not yet a mature enough technology. The performance of IPv6 in many cases proved to be worse than IPv4, incurring an overhead much higher than its anticipated theoretical counterpart.
