With the Americas running out of IPv4, it’s official: The Internet is full

In April, ARIN, the (North) American Registry for Internet Numbers, announced that it had reached "phase 4" of its IPv4 countdown plan, with fewer than 17 million IPv4 addresses remaining.

LACNIC, the Latin American and Caribbean registry, reached a similar threshold of a little more than four million remaining IPv4 addresses.

APNIC and the RIPE NCC, Europe’s registry, will give ISPs and other network operators one last block of 1024 addresses, the rules for LACNIC are similar, and ARIN is tightening the address supply but still allows ISPs to come back for more.
