2. What is an IP address? o Web address of your house, on the internet o Every website also needs an IP address Current standard IPv4 o Only 4 billion addresses o Running Out What is "Internet Protocol"? image from ArstechnicaArstechnica

3. IPv4 Created in 1981 Was the 1 st version used for internet protocol The address size is a 32-bit number There are a little over 4 billion IPv4 addresses These IP addresses are running out Some countries have already used up their IP addresses *ARIN. "IPv4 and IPv6." ARIN (American Registry for Internet Numbers). ARIN, 18 Dec. 2011. Web. 05 Mar. 2012..

4. IPv4 IPv4 uses the dotted-decimal notation Is still the standard internet protocol used throughout the world 99% of the world’s networks still use IPv4 *Joan, Ben. "Difference Between IPv4 and IPv6 | Difference Between | IPv4 vs IPv6." Difference Between Similar Terms and Objects. 05 Sept. 2011. Web. 05 Mar. 2012..

5. IPv4 vs. IPv6 The major difference between these two versions is the number of available addresses:  IPv4= 2^32= 4,290,000,000 billion addresses  IPv6= 2^128= 340,282,366,920,938, 000,000,000,000,000,000,000,000 addresses * http://mashable.com/2011/02/03/ipv4-ipv6-guide/ IPv6 reduces the size of routing tables, which consequently makes routing more efficient. * http://www.networkcomputing.com/ipv6/230500009

6. IPv4 vs. IPv6 A routing table is basically a “map” that tells data the best way to be transferred over a network. IPv6 supports multicast rather than broadcast.  “Multicast allows bandwidth-intensive packet flows (like multimedia streams) to be sent to multiple destinations simultaneously, saving network bandwidth” *http://www.networkcomputing.com/ipv6/230500009

7. IPv4 vs. IPv6 IPv6 is more efficient at processing data by eliminating IP-level cheksums. Time isn’t wasted on recalculating the same checksum at every router hop.  A checksum is a value that verifies the integrity of a file or a data transfer.  If the checksums don't match those of the original files, the data may have been altered or corrupted. *http://www.networkcomputing.com/ipv6/230500009 **http://www.techterms.com/definition/checksum

8. How Is IPv6 Emerging? Adopting IPv6 will be a very gradual transition o Content networks and service providers will be slow to adopt permanently This has provided many opportunities for existing technologies: o Digital rights management (DRM) o Radio-frequency identification (RFID) devices Running out of IP addresses o Because they ran out of IP addresses for IPv4, this is the reason there is now an IPv6. This is possible to continue when IPv6 runs out of IP addresses as well. *www.us.ntt.com/en/about-us/newsroom/press-releases http://Voicendata.ciol.com/content/bporbit/watch/111061704.as p

9. World IPv6 Launch Day June 6 th : Bunch of companies saying, we'll permanently allow IPv6 on this day Old version will continue to work Major participants, more than 400 total o Comcast o Google o Facebook o Microsoft o Cisco: make the machines that move Internet traffic *http://www.worldipv6launch.org/faq/

10. Difficulty In Switching Upgraded hardware required o New routers need to be sent out by internet companies o Expensive to give everyone new routers o Older operating systems have no clue what IPv6 is Two versions are incompatible o IPv4 can't talk to IPv6, like different languages o Parallel implementation of both is seen as best way to go People don't know what IPv6 is o Difficult to explain the problem o Many aren't interested, and just want it to work *By Logan G. Harbaugh, PCWorld,. "Why You Shouldn't Worry About Switching to IPv6 Now." PC WORLD. N.p., 2011. Web. 9 Mar 2012. <http://www.pcworld.com/businesscenter/article

11. Transition Period "The immediate challenge lies in encouraging all organisations in both the public and private sectors to make content available via IPv6, to ensure the continued growth of the internet." ("Switching to IPv6" bcs.org) o Employees will need to be retrained on how to operate and maintain new software tailored to IPv6 Some new hardware and software companies are already developing with IPv6 compatibility in mind. o helps reduce transition costs o makes the transition almost invisible, people wont know its happening o Ideally only those with hardware or software more than a few years old will experience transition costs. *"The Chartered Institute for IT." Switching to IPv6. bcs.org, 2009. Web. 9 Mar 2012..
