Background• Internet Protocol version 4 (IPv4) is used in the Internet as a

Internet Protocol now -IPv4 address assigned newly is going to disappear

23/04/21 Colloquium 3

If the IPv4 address completely disappear

• Can no longer connect device (computer, cell-phone, etc.) to the Internet

• Cannot establish a new website

As a result, development of the Internet stops

• Internet Protocol version 6 (IPv6) is going to be introduced to solve this problem

• IPv4 has 232, on the other hand IPv6 has 2128IP address This is huge number so as to remain even if assigns an IP address to stones

of the world

Main Issue

• IPv6 is not compatible with IPv4 must support both protocols during the parallel operative period

Dual Stack means that support IPv4 and IPv6 functions.

A technique that encapsulate a packet and send it in a network is tunneling

World IPv6 Day• World IPv6 Day was an event sponsored and organized by the

Internet Society started at 00:00 UTC on June 8, 2011 and ended 23:59 the same day The main motivation for the event was to evaluate the real world effects

of the IPv6 Many company participated -Google -Yahoo! -Facebook -Akamai -Limelight Networks ……

Percentage of IPv6 traffic of all Internet traffic

Conclusion

• The IPv6 is a method to solve the issue of IP address drying up

• Currently, manage two protocols of IPv4 and IPv6 parallel

• The percentage of the IPv6 is still low and will take more time to completely shift
