Finally, today (06-Jun-2012), IPv6 is launched and deployed by many of the major Internet companies like Google, Yahoo!, Facebook, MS Bing, Cisco etc as per World IPv6 Launch organization. Moreover, it was done almost one year after the World IPv6 Day held on 08-Jun-2012.
We were getting out of the IP numbers as some time we do with the phone number. Growing number of devices connected to internet made everybody to think that IPv4 is not going to provide the required IP addresses, hence came the IPv6. It may going to be normal thing in future but today it is great and it is going to be great as it was IPv4.
Happy Internet-ing! and lets give the warm welcome to IPv6.
