prop-116: Prohibit to transfer IPv4 addresses in the final /8 block

  1. 1. prop-116: Prohibit to transfer IPv4 addresses in the final /8 block Tomohiro Fujisaki APNIC 42 Open Policy Meeting Colombo, Sri Lanka Wednesday, 5 October 2016
  2. 2. 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 high, since APNIC manages about 40/8. • Based on the information provided by APNIC secretariat, number of transfers from the 103/8 block are increasing year by year.

  5. 5. Problem statement (cont.) • 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. • 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 • 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
  6. 6. 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.
  7. 7. Situation in other regions • RIPE-NCC has been discussing to prohibit transfer under the final /8 address block. • https://www.ripe.net/participate/policies/proposals/2016-03 Locking Down the Final /8 Policy Summary of proposal (..) • Bans transfers of final /22 allocations • (..)
  8. 8. 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 with the final /8 policy. • 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 with the final /8 policy.
  9. 9. 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.
  10. 10. Impact on APNIC/LIR • 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)
  11. 11. Summary • Propose to prohibit transfer IPv4 address under /8 address block (103/8). • In the case of transfers due to M&A, merged organization can have up to /22 IPv4 address in the 103/8 block. • Distribution from 103/8 block will be consistent with its original purpose: • Distribution for new entrants to the industry. • Fair distribution, one /22 from final /8 block to each LIRs.
