------------------------------------------------------- prop-116-v002: Prohibit to transfer IPv4 addresses in the final /8 block ------------------------------------------------------- Proposer: Tomohiro Fujisaki fujisaki@syce.net 1. Problem statement -------------------- There are a lot of transfers of IPv4 address blocks from 103/8 happening, both within the APNIC region and among RIRs. Then number of transfer from 103/8 block are about 200, which is about 12% of the total number of transfers. This looks so hight high, since APNIC manages about 40/8. And based on the information provided by APNIC secretariat, number of transfers from the 103/8 block are increasing year by year. Provided by George Kuo on the sig-policy ML at 8th September 2016: 1) M&A transfers containing 103/8 space +------+-----------+-----------+- | | Total | Number of | | Year | Transfers | /24s | +------+-----------+-----------+- | 2011 | 3 | 12 | | 2012 | 10 | 46 | | 2013 | 18 | 66 | | 2014 | 126 | 498 | | 2015 | 147 | 573 | | 2016 | 45 | 177 | +------+-----------+------------+- 2) Market transfers containing 103/8 space +------+-----------+-----------+ | | Total | Number of | | Year | Transfers | /24s | +------+-----------+-----------+ | 2011 | 2 | 2 | | 2012 | 21 | 68 | | 2013 | 16 | 61 | | 2014 | 25 | 95 | | 2015 | 67 | 266 | | 2016 | 56 | 206 | +------+-----------+-----------+ And also, transfers from the 103/8 block include: - Take place within 1 year of distribution, or - Multiple blocks to a single organization in case of beyond 1 year. Further, there is a case where a single organization have received 12 blocks transfers from 103 range. see: https://www.apnic.net/transfer-resources/transfer-logs From these figures, it is quite likely that substantial number of 103/8 blocks are being used for transfer purpose. This conflicts with the concept of distribution of 103/8 block (prop-062), which is intended to accommodate minimum IPv4 address blocks for new comers.  prop-062: Use of final /8  https://www.apnic.net/policy/proposals/prop-062 2. Objective of policy change ----------------------------- When stated problem is solved, distribution from 103/8 block will be consistent with its original purpose, for distribution for new entrants to the industry. Without the policy change, substantial portion of 103/8 blocks will be consumed for transfer purpose. 3. Situation in other regions ----------------------------- RIPE-NCC has been discussing to prohibit transfer under the final /8 address block. 4. Proposed policy solution --------------------------- Prohibit transfer IPv4 address under /8 address block (103/8). If the address block allocated to a LIR is not needed any more, it have to return to APNIC to allocate to another organization. In the case of transfers due to M&A, merged organization can have up to /22 IPv4 address in the 103/8 block. The 103/8 IPv4 address more than /22 have to return to APNIC to allocate to another organization. 5. Advantages / Disadvantages ----------------------------- Advantages: - It makes 103/8 blocks available according to the original purpose, as distribution for new entrants (rather than being consumed for transfer purpose) - IPv4 addresses under final /8 are not transferred to outside APNIC. - By prohibiting transfer them, it is possible to keep one /22 for each LIRs state, which is fair for all LIRs. Disadvantages: None. 6. Impact on resource holders ------------------------------ - LIRs cannot transfer address blocks under 103/8. No big impact while they use it. - Organizations which needs to receive transferred IPv4 can continue to do so, outside 103/8 blocks (which should be made available for new entrants) 7.
