An anonymous reader writes "LACNIC, the regional Internet registry for Latin America and the Caribbean, considers its IPv4 address pool exhausted, because it is down to less than a quarter of an /8, roughly 4 million IPv4 addresses which are reserved for facilitating transitioning mechanisms. Half of those addresses will be assigned on a first come, first served basis, but no more than 1024 addresses per organization every 6 six months. Allocations from the last 2 million addresses will be a maximum of 1024 addresses total per organization. To maintain connectivity, it is now indispensable to make the switch to IPv6. LACNIC's CEO expressed his concern that many operators and companies still haven't taken the steps needed to duly address this circumstance. The RIRs for Asia-Pacific, Europe and North America have all imposed similar limitations on IPv4 assignments when they also crossed their local exhaustion thresholds. As of now, only AfriNIC is not in address exhaustion mode." Joining North America, and Europe/the Middle East/Central Asia.
