Transcript Goodbye IPv4*

Goodbye
IPv4…
Hello IPv6!
Why the change?
IPv4 – 1980’s
IPv6 – 2000’s
IPv4 – What Happened Bro?
 32 bit address
 Limited to only 4.3 billion addresses
 Slow header processing by router
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
IPv6 - Why, Hello there.
 128 bit address
 340 undecillion addresses (5 x 1028 addresses per PERSON)
 Faster Header processing
 Example IPv6 address 2001:0db8:85a3:0000:0000:8a2e:0370:7334
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.
Why must we say goodbye?

IPv4 Depletion
 4.3 billion addresses used?
IPv6 to save the day! (kinda)
Slow Deployment
 Expensive cost of upgrading hardware to IPv6
 No dire need for change
 Testing is difficult
 Already existing support since Windows XP
World IPv6 Day
World IPv6 Day
 June 8, 2011
 Internet Giants will switch for one day
 Google estimates only 0.09% of users will have problems
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!
