As of today, LACNIC (the IP address registry for Latin America and the Caribbean) are down to 1.05 /8s remaining, which means that it is likely in the next day or two to have reached the final /8 that they have. LACNIC have slightly different rules to some of the other registries – RIPE and APNIC, for example, considered their stock of IPv4 addresses to be exhausted when they reached the final /8 (16,777,216 addresses) , whereas ARIN are taking a different approach and are basically reserving hardly any, so it truly is a “race to the bottom” for that region although the requirements for obtaining a block when they reach the final /8 are much increased. LACNIC consider their addresses to be exhausted when they reach 4,194,304 addresses (/10) left.
Yesterday there were 524,288 addresses (/13) allocated to Telemar Norte Leste S.A. in Brazil, and a further 393,216 addresses split as two blocks of 262,144 (/14) and 131,072 (/15) addresses to Telefonica de Argentina. If this rate of allocation continues (i.e. 0.05 /8s per day), LACNIC will be out of addresses in 16 working days from now. I suspect it won’t be depleted that quickly, but still a sobering thought, if you still have your head in the sand over IPv4 exhaustion and you’re located in the LACNIC region.
