It is recommended that APNIC 30 Plenary attendees read this document before attending the session:
IPv4 Tomorrow? Community consultation on the finer details of the IPv4 run-out policy
Abstract
As we move into the final stages of IPv4 address distribution, the Internet community will face some issues on how to deal with the remaining IPv4 address space. With only 14 /8 blocks left, it won't be long before all the RIRs receive their last /8 from IANA.
Although APNIC has adopted some policies to manage the final stages, there are some operational and perhaps policy issues that still remain:
(1) Should APNIC reserve the final /8 from IANA for distribution under the policy for the Distribution of the final /8 worth of space in the unallocated APNIC IPv4 address pool?
Under the policy as written, it is up to the APNIC Secretariat to decide whether to reserve the last /8 allocated to APNIC for this policy. However, if APNIC does reserve the last IANA block for this purpose, it means that if there is a large request, APNIC may have to combine multiple smaller prefixes to make up the required allocation size. This will cause some fragmentation of the address space.
(2) How exactly should APNIC define when the last /8 worth of space is reached?
APNIC has a number of prefixes that are reserved in a 'quarantine pool' until its RQA processes have been completed. For example, this applies to returned address ranges and to new /8s from IANA, or blocks receiving significant levels of leakage of informal use as private address ranges such as 1.0.0.0/16. Should APNIC count these 'quarantined' addresses as part of the available pool and allocate them before the final /8 can be deemed to have been reached?
(3) When the final /8 is reached, how should APNIC handle the return of addresses?
If returned addresses take the total APNIC unallocated pool back over a /8, does that trigger a repeal of the final /8 policy until the pool becomes lower than a /8 again? Should returned addresses be allocated according to the final /8 allocation policy or according to another policy?
