APNIC's IPv4 pool usage
Bar Graph: APNIC IPv4 Available Pool
The above bar graph shows APNIC pool of Available IPv4 addresses. It shows the daily total of IPv4 addresses, expressed in terms of /8s. The total decreased and increased according to APNIC allocations to networks, delegations of /8s received from IANA, and resource returns.
On 15 April 2011, the APNIC pool reached the last /8 of available IPv4 addresses, triggering the Final /8 policy.
Pie Graph: APNIC IPv4 address pool
The above pie graph shows how APNIC's IPv4 address holdings are currently managed.
Now that the Final /8 policy has been implemented, the following processes apply to the three main IPv4 categories:
Available:
Given the final /8 policy permits each LIR to receive only one small block (a /22), and that APNIC regularly receives returned IPv4 resources when LIRs close, it will take a very long time to delegate its entire IPv4 pool. For more information, see IPv4 exhaustion details.
Reserved:
Quarantined blocks will be released to the Available pool when their routability and usability problems are minimized.
Delegated:
There is no change to how delegated addresses are managed.
