Yahoo!®: IPv6 upgrade threatens Intenet Users

The Internet Protocol version 4 in current use will suffer an IPv4 address exhaustion in this decade, experts argue it could be as soon as this year or max in 2 to 3 years. This necessitates the induction of IPv6. When IPv$ was started in the late eighties such widespread usage of net and so many domain names were not expected hence it was thought that IPv4 would suffice. However reports by CISCO and others in early 2000s stated that the pool of available addresses would dry up in as little as 4 to 5 years.

Yahoo is the most vocal of this problem and has started with a move to IPv6 on its main website by the end of this year despite worries that up to 1 million users will suffer from IPv6 Brokenness. Yahoo is concerned about the fact that 0.05% of internet users won’t be able to access the sites that support both IPv6 and the current standard IPv4.

At an Internet Engineering Task Force meeting in Toronto in 1994 it was decided to replace the 32 bit addressing system of IPv4 with a 128 bit addressing system of IPv6. A framework was set. However due to the expensive and time consuming nature of the job no major carrier has made a step in this direction. According to the latest prediction of max 1200 days left until the internet runs out of the IPv4 addresses the US federal Government had mandated all agencies to support the new protocols by July 2008.

June 8 2011 is being celebrated as World IPv6 day and is being supported by Facebook , Google and Yahoo. These and many more major web based services and sites will switch to IPv6 on June 8th to spread awareness about IPv6 and the global Web Address shortage due to the limitations of IPv4.
