How the membership structure works

APNIC's membership structure is divided into seven tiers. These tiers are: Associate, Very Small, Small, Medium, Large, Very Large, and Extra Large.

The total amount of IPv4 or IPv6 address space holdings are reviewed at the membership renewal each year to determine what membership tier a the member will be on.

If a Member holds both IPv4 and IPv6 address space, the tier is assessed by comparing the IPv4 and IPv6 address space holdings. The higher tier associated with either the IPv4 or IPv6 holding will be the effective membership tier at the time of renewal.
