1. IPV4 TO IPV6 By Justin Bode for CPE 401 @ UNR

2. Introduction  Why do we need a new version of IP?  What does IPv6 look like?  New features of IPv6  How will it be implemented?  Conclusion

3. Why a New Version? IPv4: 32-bit address space 2 ^ 32 = 4,294,967,296 That’s over 4 billion addresses! Only 3,706,650,624 are usable Appoximately 671,645,000 are still available

4. Why a New Version?

5. IPv6: 128-bit address space 2 ^ 128 = Well… 2 ^ 128 ≈ 340,282,366,920,938,463,463,374,607,431,770,000,000

6. Why a New Version?

7. What Does IPv6 Look Like?

11. New Features  Large address space!  Stateless address auto-configuration  Multicast  Mandatory network layer security  Simplified processing by routers  Jumbograms

12. New Features

13. How Will It Be Implemented?  Routers  Software  People who know how to use it

14. How Will It Be Implemented?

16. Conclusion  We will run out of IPv4 addresses. Need a larger address space.  IPv6 will solve the problem and enhance performance.  There are several new features in IPv6 (Jumbograms!)  Need routers, software, and people to implement IPv6.

17. Questions?
