North America Is Out of IPv4 Addresses—for Really Real This Time
As of yesterday, North America is out of IPv4 addresses. Getting that feeling of déjà vu all over again? In July, we reported that ARIN, the American Registry for Internet Numbers, was activating its waitlist policy, wherein organizations that qualify for a block of IPv4 addresses larger than the largest block in ARIN’s available pool of addresses could opt to wait for that larger block to become available. Organizations requesting block sizes that were still available would still receive IPv4 addresses. But as of September 24, ARIN no longer has any IPv4 addresses available to be given out to organizations in the region. The pool is empty. This time, it’s for real.
So organizations in the US, Canada, part of the Caribbean, and some additional islands will either have to take their chances on the waitlist, buy IPv4 addresses from someone else, or use IPv6 instead. In an earlier interview, ARIN CEO John Curran told Ars that he expects very little new IPv4 address space to become available at ARIN, so those on the waitlist shouldn’t get their hopes up.
