1. Goodbye IPv4…

2. Why the change? IPv4 – 1980’sIPv6 – 2000’s

3. IPv4 – What Happened Bro?  32 bit address  Limited to only 4.3 billion addresses  Slow header processing by router

4. IPv4 – You won’t be forgotten!  Gave us NAT (Network Address Translation)  Lasted 3 decades!  IPv4 support will continue… for few…  Easy to say dot decimal addresses ex. 192.168.1.1

5. IPv6 - Why, Hello there.  128 bit address  340 undecillion addresses (5 x 10 28 addresses per PERSON)  Faster Header processing  Example IPv6 address - 2001:0db8:85a3:0000:0000:8a2e:0370:7334

6. IPv6 – New Innovations  Multicasting - the transmission of a packet to multiple destinations in a single send operation  Stateless address autoconfiguration (SLAAC) - IPv6 hosts can configure themselves automatically when connected to a routed IPv6 network  IPsec – Internet Protocol Security integrated into network layer.

7. Why must we say goodbye?

8. Audience Participation Time!

9. Which of these devices need an IP address?

14. IPv4 Depletion  4.3 billion addresses used?

15. IPv6 to save the day! (kinda)

16. Slow Deployment  Expensive cost of upgrading hardware to IPv6  No dire need for change  Testing is difficult  Already existing support since Windows XP

17. World IPv6 Day

18.  June 8, 2011  Internet Giants will switch for one day  Google estimates only 0.09% of users will have problems

19. So When is the Switch?  The near future… (nobody knows)  Google’s 6to4 technology will aid users with issues  Be prepared or be left in the dark!
