If you had asked John Curran, head of the American Registry of Internet Numbers (ARIN), three years ago to pinpoint the date at which we would run out of IP address space under IPv4, he would have said 2025.
Two years ago, his answer would have been 2017.
On Wednesday, he told an audience at the Burton Group’s Catalyst Conference that the doomsday date is now 2011. That’s not a scare tactic – it’s a fact based on the rapidly increasing pace at which blocks of addresses are being allocated, according to Curran.
He said that 68% of all available IPv4 addresses are gone and only 19% are available. The remaining 13% fall into a strange category of being unavailable, which means blocks of addresses that belong to a large company, a university or an ISP and are not used.
