Summary
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



Five principles of ip address policy
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


Aggregation
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


Conservation efficient use
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


Fairness
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.


A couple of ideas and call for your thoughts

A couple of ideas andcall for your thoughts


How about charging for all ip address blocks
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


The last minute fairness
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
