________________________________________________________________________ prop-071: Justifying receiving IPv4 address space ________________________________________________________________________ Author: Philip Smith pfs@cisco.com Version: 1 Date: 10 March 2009 1. Introduction ---------------- This policy proposal seeks to supplement prop-050, "IPv4 address transfers", by requiring recipients of transferred IPv4 address space to justify its use. 2. Summary of current problem ------------------------------ Prop-050, "IPv4 address transfers", as it stands at time of writing, places no requirement on the recipient of transferred IPv4 address space to justify their need for the additional address space before APNIC registers the transfer. This can allow any organisation the opportunity to stockpile IPv4 address space, to the detriment of the entire industry during the IPv4 runout period. 3. Situation in other RIRs --------------------------- RIPE NCC The transfer policy adopted by RIPE only permits transfers to take place if the recipient can justify the need for address space to the RIPE NCC. Recipients of transfers cannot transfer any portion of that address space to another organisation within 24 months. See: http://www.ripe.net/ripe/policies/proposals/2007-08 ARIN The transfer policy specifically states the justification conditions under which transfers are permitted in the ARIN region - see section 8.2 at: http://www.arin.net/policy/proposals/2007_8.html LACNIC LACNIC is currently discussing a transfer proposal: LAC-2009-04 Transfer of IPv4 Blocks within the LACNIC Region http://www.lacnic.net/documentos/politicas/LAC-2009-04-propuesta-en.pdf AfriNIC has no transfer policy. 4. Details of the proposal --------------------------- It is proposed that: 4.1 Until such a time when the prevailing APNIC IPv4 allocation practice uses the "final /8" policy [1], the recipient of a transfer is to justify use of transferred space using the allocation and assignment policies in force at the time of the transfer. 4.2 After that time, no justification is needed. 4.3 Recipients of transferred address space are not permitted to transfer any portion of this address space to another organisation for at least 24 months. 5. Advantages and disadvantages of the proposal ------------------------------------------------ 5.1 Advantages - Recipients of IPv4 address transfers will have to fully justify receiving the address space, just as they do for any current direct allocations or assignments from the APNIC pool. 5.2 Disadvantages - None. 6. Effect on APNIC members --------------------------- The proposal impacts all APNIC members in that they now will have to fully justify transfers they receive under proposal-050. 7. Effect on NIRs ------------------ The proposal has no direct impact on NIRs, but impacts members of NIRs in the same way it impacts APNIC members. 8.
