A worldwide test was under way on Wednesday of the next generation of Internet addresses designed to replace the exhausting pool of 4.3 billion unique identifiers in the original system.
Hundreds of companies, organizations and institutions around the world are taking part in “World IPv6 Day,” including Internet giants such as Facebook, Google, Microsoft and Yahoo!
Internet Protocol version 6 is the new system of unique identifying numbers for websites, computers and other Internet-connected gadgets and is replacing the original addressing system, IPv4, which is nearing exhaustion.
IPv6 provides more than four billion times more addresses than IPv4 – more addresses.
The number of available IPv4 addresses will run out later this year and the transition to IPv6 is needed to keep pace with the exponential growth in Internet use.
United States networking company Cisco forecast in a report released this month that the number of devices connected to the Internet will top more than fifiteen billion by the year 2015, more than double the world’s population.
