RIPE NCC handing out its last block of IPv4 addresses, tries to fend off internet survivalism
In a world where IPv6 lives and IPv4 addresses are scarce, network providers must fight for survival... or at least, claim their IP blocks quickly. The RIPE NCC, the regional internet registry for Asia, Europe and the Middle East, warns that it's down to assigning its last set of 16.8 million IPv4 addresses as of this weekend. That sounds like a lot, but we'd do well to remember that the registry churned through about 5.2 million addresses in just the past two weeks. What's left won't be around for long, folks. To cut back on the number of Mad Max-style battles for dwindling resources, RIPE NCC is rationing out IPv4 for local registries in 1,024-address chunks -- and only to those who both have IPv6 assignments as well as proof of a need for IPv4. With just a bit more than half of the RIPE NCC's customers currently on IPv6, that could still trigger a shortfall among networks that haven't prepared for the internet protocol apocalypse. We'd advise that companies stock up on IPv6 supplies before launching the raiding parties.
Vint Cerf on IPv4 depletion: 'Who the hell knew how much address space we needed?'
Father of the internet, Vint Cerf, is taking one on the knuckles this week for the inevitable diminution of the world's IPv4 addresses. Last Friday, The Sydney Morning Herald ran a sensational story titled, "Internet Armageddon all my fault: Google chief," in which Cerf warned of an end to unique IP addresses "within weeks." The story was, of course, a bit tongue-in-cheek, considering the industry has long anticipated and prepared for said Armageddon. Back in 1977, Cerf led a team of DARPA researchers in creating IPv4, which limits IP addresses to four 8-bit numbers or 32-bits total, providing for 4.3 billion addresses: not nearly enough by today's standards. In the article, Cerf said he never expected his protocol to take off, adding, "Who the hell knew how much address space we needed?" The IPv4's successor, IPv6, which enlists four 32-bit numbers or 128 bits total, was developed soon after Cerf's protocol and is now getting attention from internet giants like Google and Facebook, who will launch World IPv6 Day this June. Considering IPv6 makes for 340,282,366,920,938,463,463,374,607,431,768,211,456 unique addresses, we probably won't be hearing of an IP apocalypse anytime soon.
