  1. From IPV4 to IPV6..., How far have we come???How far to go??? Course:- Introduction to Networks and Communication. Prof:-Dr. Kurt Maly Student:-LoksaiPulivarthi

  2. Overview • Why IPv6? • How much IPV4 is left? • How much IPV6 is being used? • Do we have a problem? • What Next?

  3. What is IP and IPV4? • “IP” is the internet protocol, the set of digital communication codes which underlies the internet infrastructure. • IP allows the flow of packets of data between any pair of points on the network providing the basic service up on which the entire internet is built. • Without IP, the internet as we know it would not exists.

  4. Why, what is IPV6? • Currently the internet makes use of IPV4 which is now reaching the limits of its capacity to address additional devices. • IPV6 is the “Next Generation of IP” which provides a vastly expanded address space. • Using IPV6, the internet will be able to grow to millions of its times its current size, in terms of number of people, devices and objects connected to it.

  5. Other reasons for choosing IPV6 • More Efficient Routing. • More Efficient Packet Processing. • Directed Data Flows. • Simplified Network Configuration. • Support For New Services. • Security.

  6. How much IPV4 is left?

  7. Coexistence of IPv4 and IPv6 (“Dual Stack”) Size of the Internet IPv6 Deployment The Transition Plan… IPv4 Deployment Time

  8. Bigger • IPV6 is massively bigger than IPV4. • There is plenty of IPv6 space left for new networks connecting from developing countries over the next 100+ years.

  9. Disadvantages of IPV6 • It will be much harder to remember IP addresses (compared to the addresses now). • Creating a smooth transition from IPv4 to IPv6. • IPv6 is not available to machines that run IPv4. • Any consumer costs in having to replace an IPv4 machine. • Time to convert over to IPv6.
