Remaining IPv4 Addresses to be Redistributed to Regional Internet Registries – IPv4 is Nearing Total Exhaustion
This move signals that the global supply of IPv4 addresses is reaching a critical level. As more and more devices come online, the demand for IP addresses rises, and IPv4 is incapable of supplying enough addresses to facilitate this expansion. ICANN encourages network operators around the globe to adopt IPv6, which allows for the rapid growth of the Internet.
“We are grateful for the guidance we’ve received from the RIR‘s as the number of unallocated IPv4 addresses dwindles,” said Elise Gerich, Vice President of IANA and Technical Operations at ICANN. “This redistribution of the small pool of IPv4 addresses held by us ensures that every region receives an equal number of addresses while we continue to work with the community to raise support for IPv6.”
To handle this critical drop in the numbers available to LACNIC, the five RIRs’ policy making communities established a policy for the equal redistribution by ICANN. This is known as the allocation phase outlined in the Global Policy for Post Exhaustion IPv4 Allocation Mechanisms.
“The IANA IPv4 Recovered Address Space registry contained about 20 million IPv4 addresses earlier today and is now about half that size,” said Leo Vegoda, Operational Excellence Manager at ICANN. “Redistributing increasingly small blocks of IPv4 address space is not a sustainable way to grow the Internet. IPv6 deployment is a requirement for any network that needs to survive.”
IPv6 facilitates the exponential growth of the Internet by providing 340-undecillion unique addresses, compared to the 3.7 billion afforded by IPv4.
“To continue to fuel the economic growth and opportunity that is brought by the Internet, we are at the point where rapid adoption of IPv6 is a necessity to maintain that growth,” said Gerich.
