Conclusion


IPv6 is designed to accommodate the much greater global demand for translation of vast real-time data of complex transmission systems and to solve problems of the limitation of IPv4 address space. IPv6 offers a number of new features and simplifications, which will provide additional services on the Internet.
 

IPv6 will have some influence on improving the general security of the Internet, because IPv6 machines will be able to tunnel directly to each other with no need for the virtual private network (VPN).
 

IPv6 will eventually replace Ipv4 and become the standard for the global Internet. The two protocols will coexist for several years until the transition is complete. The full transition to IPV6 will take at least a decade.
 

The greatest demand for new IPv6 addresses is in Asia. For example, the population of China is more than one billion, but China has only less than 30 million IPv4 addresses available. So the large states in Asia like China and Japan are adopting the IPv6 technology, because they need IP addresses and have no other choice [12].
 

The mission of Internet measurement projects is to analyze Internet topology and performance. They are designed, for example, to measure IP paths, collect round-trip performance data, track persistent routing changes, and help visualize network connectivity or provide selected IP multicast measurements for Internet sites such as loss, delay, jitter, round trip time (RTT), packet loss, topology, and throughput [13].
 

The Active Measurement Project (AMP) performs site-to-site active measurements and analyses; it is used for detecting link congestion, catching the impact of routing changes, and other diagnostics. It is used to detect link congestion, catch the impact of routing changes, and other diagnostics.
 

The active measurements project (AMP) of NLANR/MNA (NLANR Measurement and Network Analysis) includes IPv6 measurements [13].
 

Currently there are 11 Sites [SURFnet will be added shortly] that host an IPv6 AMP box for NLANR/MNA.
 

The site, hosting AMP IPv6 measurement endpoints, also hosts IPv4 AMP endpoints (on the same box). NLANR/MNA can compute the relative performance of both IPv6 and IPv4. It has been found by measurement that the performance of IPv6 is getting every day better than IPv4, partly depending on the topology of the underlying networks.
