World IPv6 Launch

World IPv6 Launch

June 6 2012, is being celebrated worldwide as the IPv6 Launch Day, I just added an IPv6 to my blog and the IPv6 of this blog is 2607:f298:1:107::c53:5ffc

IPv6 was planned in the year 1996 but took decades to get launched many ISP's are still not supporting it but will soon start supporting the same. ISP's in India are yet to start their support to IPv6.

Here is a video of Vint Cerf, Chief Internet Evangelist at Google, and a founding father of the Internet, discusses the next version of the Internet, IPv6, and why we need it.
