ARIN, the North American company which assigns IP addresses in North America has announced that on July 1st it has finally run out of numbers of IPv4 addresses. For the first time, ARIN didn't have enough IP addresses left in its stock to satisfy an entire order — and now, it's activated the end-times protocol that will see the few remaining addresses out into the night.

"If you take a smaller block, you can't come back for more address space for 90 days," John Curran, CEO of ARIN, says. "We currently have nearly 500 small blocks remaining, but we handle 300 to 400 requests per month, [so] those remaining small blocks are going to last between two and four weeks."

IP addresses are crucial to the operation of the Internet. They're the numbers behind URLs like "" or "" They identify every device that connects to the Web, from servers to connected cars. The original designers of the Internet thought they'd only need around 4 billion unique combinations, derived from the series of dots and digits that make up IP addresses everywhere.

However, it's not the end of the world, because there's a newer, more robust system rolling out, the IPv6. The old system had 4.3 billion combinations - the new one (IPv6) has some 340 trillion trillion trillion combinations.
