  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 WOW! 2 ^ 32 = 4,294,967,296 That’s over 4 billion addresses! But… Only 3,706,650,624 are usable But… Appoximately 671,645,000 are still available But…

  4. Why a New Version?

  5. Why a New Version? 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?

  8. What Does IPv6 Look Like?

  9. What Does IPv6 Look Like?

  10. 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?

  15. 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.
