IPv4 Addresses Scheduled to Be Depleted in April 2012

John Curran, CEO of the American Registry for Internet Numbers (ARIN), has been sounding the alarm for several years about the importance of putting a framework in place for the transition to an IPv6 addressing protocol, which will provide an unlimited number of Internet Protocol (IP) addresses.  Service providers, industry groups and vendors are moving toward just that.  Holders of IPv4-based networks and web sites will run in “dual-stack mode” supporting both protocols as the transition continues, with IPv4 addresses scheduled to be depleted in April 2012.

The internet operates by transferring data in small packets, routed across networks.  Every host or computer has it’s own IP address.  So when a computer requests a packet of information from a host, the request is made to the correct address, and the packet is delivered to the correct IP address.  The tremendous growth of the internet has necessitated a new protocol for producing these IP addresses.

In June 2011 three was an event known as IPv6 day, that acted as a dress rehearsal of sorts to enable service providers to have dual runs while they tested the effects.  The event was successful in that there were no serious incidences.  However, home networking vendors such of items such as routers also need to ensure that these devices work under the new protocol.

It’s all about creating awareness . . . for service providers, vendors, and businesses, about having an IPv6 transition plan in place to ensure that seamless interaction among IP addresses continues after the depletion.
