Change to minimum prefix size on APNIC IPv4 address blocks ________________________________________________________________________

In response to feedback from the community at APNIC 30, the prefix size on all APNIC IPv4 address blocks has been changed to a /24.

This change enables the IPv4 transfer policy to apply to all APNIC ranges. The new size also allows Members to downgrade their membership by returning unused IPv4 addresses.

Please update your network configurations, such as router filter sizes based on the IPv4 address block minimum prefix size where required.

For more information on IPv4 prefix sizes, please refer to:

Kind regards,
