The IPv4 minimum allocation size for the networks in APNIC region has now been lowered to a /21 (2,046 addresses). 

The new minimum allocation size and revised eligibility criteria lower the entry barriers for networks seeking portable address space. Some networks that previously had to use resources from an upstream provider will now be able to receive IPv4 addresses directly from APNIC.

Previously, an organization had to justify the need for a /20 (4,096 addresses) to be eligible for an allocation from APNIC.

The new eligibility criteria for an initial allocation require that an organization must:

• have used a /23 from their upstream provider or demonstrate an immediate need for a /23;
• have complied with applicable policies in managing all space previously allocated to it;
• demonstrate a detailed plan for use of a /22 within a year; and
• commit to renumber from previously deployed space into the new address space within one year.

The new lower minimum allocation size was introduced on 16 August 2004.
