------------------------------------------------------- prop-117-v002: Returned IPv4 address management and Final /8 exhaustion ------------------------------------------------------- Proposer: Tomohiro Fujisaki fujisaki at syce dot net 1. Problem statement -------------------- APNIC currently makes delegations from two IPv4 pools. These are the 103/8 (Final /8) pool and the non-103/8 IPv4 Recovered pool. With current policy, all returned address space, including 103/8 blocks, will be merged into the IPv4 Recovered pool. If a 103/8 block is returned, it is placed in the IPv4 Recovered pool and re-distributed as returned space. Some organisations may receive duplicate blocks from 103/8: one under the final /8 policy, the other under the returned pool policy. Current APNIC Policy requires account holders to receive address space from the 103/8 (Final /8) pool before they can apply for address space from the Recovered pool. APNIC currently manages a Recovered Pool Waiting List for approved requests that cannot be met from the IPv4 Recovered pool. 2. Objective of policy change ----------------------------- To simplify the address pool management and to provide guidance for 103/8 pool exhaustion. 3. Situation in other regions ----------------------------- None. 4. Proposed policy solution --------------------------- Handling reurned address: - Recovered 103/8 space will be placed in the 103/8 (Final /8) pool. - Recovered non-103/8 space will be placed in the IPv4 Recovered pool. Guidance for 103/8 pool exhaustion: - The first time an approved request cannot be fulfilled from the 103/8 pool, Final /8 delegations will end. - APNIC will begin to manage only one (Recovered) IPv4 pool containing any residual 103/8 space and all future returns, including 103/8 returns. - Each new account holder can receive up to a /21 from the IPv4 Recovered pool. - Existing account holders who have not yet received the maximum /21 from the two pools may continue to apply for space from the Recovered pool until they have received a maximum /21 from the two pools. - A waiting list will be created if approved requests cannot be fulfilled. Each new account holder will be given priority in the waiting list. 5. Advantages / Disadvantages ----------------------------- Advantages: - Simplifying management of remaining IPv4 address pools. Disadvantages: None. 6. Impact on resource holders ------------------------------ No impact to resource holders. 7. References -------------
