This document summarizes IPv4 address transfer trends from 2010-2016. It finds that the number of intra-RIR and inter-RIR transfers has been increasing. While transfers into the APNIC region have also been rising to meet regional demand, some final /8 addresses have been transferred unused to other regions, with a few members holding more than a /22 from the final pool. The report observes that resources have been transferred from ARIN to APNIC to address IPv4 needs in the Asia Pacific region.

11. Observations
• Large amount of historical resources transferred from ARIN
region to APNIC region to meet the IPv4 demand in our
region
• 175 members have more than /22 IPv4 from the final /8
• Final /8 addresses have been transferred before they were
even used
• Final /8 addresses have been transferred to other regions
outside the Asia Pacific
