Enterprise Networking Planet: This morning, the Internet Assigned Numbers Authority (IANA) allocated the last two free blocks of IPv4 addresses to the Asia Pacific Network Information Centre (APNIC). With that allocation, only 5 blocks of IPv4 addresses remain. Each block includes 16 million addresses. Under existing policy, the IANA will distribute one of those blocks to each of the regional Internet registries.
As of the first of the year, the registry that distributes addresses in North America had 4.92 blocks left and expected to exhaust those addresses within six to nine months.
