Current Affairs on Science and Technology - 2012

World IPv6 Launch Day began on June 6th.
Global transition from Internet Protocol version 4 (IPv4) to Internet Protocol version 6 (IPv6) began on June 6th. In India 27 websites have been brought on IPv6 platform. Further, a direction has been issued to all the Government organizations to migrate their websites to IPv6 (dual stack) by December 2012. As IPv6 is not backward compatible with IPv4, the transition to IPv6 is likely to be a complex and long term exercise during which both IPv4 and IPv6 will co-exist. India has at present 35 million IPv4 addresses against a user base of about 360 million data users. In addition, Government is planning to have a target of 160 million and 600 million broadband customers by the year 2017 and 2020 respectively.

Moreover, there is a strong security requirement to provide unique IP address to each individual data user. In addition to addressing capacity, IPv6 also offers several other advantages over IPv4. IPv6 has been designed with many new features which make it possible to develop entirely new applications which are not possible in the IPv4 protocol e.g.Centralized Building Management System,Intelligent Transport Systems, Rural Emergency Health Care, Tele-education / Distance Education, Smart Grids etc. IPv6 is not just about addresses but about applications taking advantage of the new features built into the protocol.
