It’s official... there are no more IPV4 (Internet Protocol version 4) Internet addresses available, which means the future expansion of the Internet is now dependent on the successful global deployment of the next generation of Internet protocol, called IPv6.
At a news conference in Miami, Florida, ICANN (Internet Corporation for Assigned Names and Numbers) joined the Number Resources Organisation (NRO), the Internet Architecture Board (IAB) and the Internet Society in announcing that the pool of first generation Internet addresses has now been completely emptied.
The final allocation of Internet addresses was administered by the Internet Assigned Numbers Authority (IANA), which is a function of ICANN.
“This is a major turning point in the on-going development of the Internet,? said Rod Beckstrom, ICANN’s President and Chief Executive Officer. “No one was caught off guard by this. The Internet technical community has been planning for IPv4 depletion for some time. But it means the adoption of IPv6 is now of paramount importance, since it will allow the Internet to continue its amazing growth and foster the global innovation we’ve all come to expect.?
The new Internet protocol, IPv6, will open up a pool of Internet addresses that is a billion-trillion times larger than the total pool of IPv4 addresses (about 4.3 billion), which means the number of IPv6 addresses is virtually inexhaustible for the foreseeable future.
