IPv6 is the new version of internet which is launched today. Internet was designed in 1973 and in 1983 it was launched as an experiment. Chief Internet Evangelist Vint Cerf who is also know as one of the father’s of Internet quoted that “Internet was an experiment which never ended”.

A device need an I.P address to connect to internet. IP address is just like a phone number which allows one device to connect with another device. Without an IP address it will be impossible for anyone to connect to internet. As it was an experiment and creators never thought that billion of devices will be connected to internet. So 1983 when Intent was launched, creators of internet allocated address space which sufficient to provide 4.3 billion IP addresses. 4.3 billion address  was a big number when internet was designed but the current situation is that internet is running out of IP address.

In 1996 IPv6 was designed and it has 128 bits of space address and now the limit is 2^128 addresses—more than 340 trillion, trillion, trillion. That is a big number. Can we exhaust this number?

Last year in February Internet Assigned Number Authority ran out of addresses to allocate Regional Internet Registries. If IPv6 is not launched soon netizens have to share IP addresses. Google point of view on this sharing IP addresses is  ”This tangled constrained internet address would be unsafe and unsustainable to use”.

IPv6 is launched today in coordination with Internet Society, supported by Number resource organization and Regional Internet Registries. Leslie Daigle, Chief Internet Technology Officer for the Internet Society said that ““World IPv6 Launch is a permanent step forward to ensure the Internet can connect all the people in the world, for many years to come”.

Google is one the founding participant’s of IPv6. Google commented on the launch of IPv6

[highlighter color="gray" ]We’re proud to be one of the founding participants; virtually all Google’s services have been available over IPv6 for a while, but IPv6 access was only available to networks participating in the “Google over IPv6” program. From now on, they will be made available to any IPv6 network on the Internet [/highlighter]

Facebook, Google, Bing and Yahoo are world renowned websites who have joined IPv6. As per the information provided on the website of  the world IPv6 launch  3004 website operator, 65 network operator and 5 Home router vendor operator ha joined. Transition from IPv4 to IPv6 will take time.
