Asia Pacific Network Information Center (APNIC) today announced it has reached the last block of its available pool of IPv4 addresses. The day is marked as key turning point which initiates a major change in regional delegation policy. From today’s announcement [PDF]:

This event is a key turning point in IPv4 exhaustion for the Asia Pacific, as the remaining IPv4 space will be ‘rationed’ to network operators to be used as essential connectivity with next-generation IPv6 addresses. All new and existing APNIC Members who meet the current allocation criteria will be entitled to a maximum delegation of a /22 (1,024 addresses) of IPv4 space.

APNIC Director General Paul Wilson explained the Asia Pacific region is the first to reach the point of being unable to meet IPv4 demand. This is due to the unprecedented fixed and mobile network growth the region is experiencing.

“Considering the ongoing demand for IP addresses, this date effectively represents IPv4 exhaustion for many of the current operators in the Asia Pacific region,” Wilson said. “From this day onwards, IPv6 is mandatory for building new Internet networks and services.”
