By Justin Bode for CPE 401 @ UNR

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

Why a New Version?

IPv4: 32-bit address space2 ^ 32 = 4,294,967,296That’s over 4 billion addresses!

Only 3,706,650,624 are usable

Appoximately 671,645,000 are still available

WOW!But…

But…

But…

Why a New Version?

Why a New Version?

IPv6: 128-bit address space2 ^ 128 = Well…

2 ^ 128 ≈ 340,282,366,920,938,463,463,374,607,431,770,000,000

New Features

Large address space! Stateless address auto-configuration Multicast Mandatory network layer security Simplified processing by routers Jumbograms

New Features

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

How Will It Be Implemented?

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.
