  1. Policy Considerationsduring IPv4 Address Exhaustion Period? MAEMURA Akinori maem@maem.org

  2. Summary • Again, English version of "Analysis and Recommendations on the Exhaustion of IPv4 Address Space"is now available on JPNIC Web • One click from http://www.nic.ad.jp/en/ • Hard copies are available at the Registration Desk outside • Mandarin version will be available from NIIEPA, Taiwan • This presentation shows a couple of idea as an Internet Registry • Responding to Expert Team’s recommendations • For your discussion with closer eyes on this issue

  3. Principles of IP Address Policy

  4. Five principles of IP Address Policy • http://www.apnic.net/docs/policy/add-manage-policy.html • Uniqueness • Inherent • Registration • Inherent • Aggregation • less important because of smaller available space • Conservation • Important not only for new assignees but existing ones, especially who hold early big assignments • Fairness • Mush more important because of very limited available space

  5. Aggregation • More efficient aggregation will need larger allocations • Larger allocations with limited address space will result in smaller number of allocation • Lucky ISPs will hold and unlucky ISPs will miss • Aggregation will be respected less than fairness and Conservation

  6. Conservation / Efficient Use • Current policy allows an assignee to hold “as many IP addresses as the assignee actually needs” • Can we ask applicants “please get less IP addresses than you actually need?” • That should be asked after an enabling technology is available • No, we cannot. • Internet Operators are aware of hoarded-up IP addresses • Some think “IPv4 address will never depleted if class-As are returned to registries

  7. Fairness • The very most important when we share the limited resource • It will be unfair if lucky ISPs hold and unlucky ISPs miss • It will be unfair if someone need to struggle to squeeze the efficiency of IP address use while some others do not need that but just put them.

  8. A couple of ideas andcall for your thoughts

  9. How about charging for all IP address blocks? • Charging for all IP address blocks in a uniform fee schedule, even for the earliest assignments • /8 => XL => USD40K/year • /16 => Medium => USD5K/year in case of APNIC • consistent sharing of the cost of IP numbers management • Fairness between earlier and later allocations • Making an incentive to return unnecessary IP address • Efficient use of unused IP address space

  10. The last minute fairness • Imagine the last block allocation. • The interest of obtaining IPv4 address conflicts. • The network plan (≒investment plan) should take into account the amount of available IP address • Adjustments will be done much earlier than the last minute • How about the “Patent Office Model” ? • Information of pending applications is disclosed • To allow them to see the trend of consumption earlier than consumed • It should work for having Carriers realize the exhaustion

  11. Your thoughts? Policy Consideration during the period of IPv4 address Exhaustion ? MAEMURA Akinori maem@maem.org
