[sig-policy] prop-094-v002: Removing renumbering requirement from final
Dear SIG members
Below is an updated version of the proposal that includes elements
changed during the APNIC 31 Policy SIG meeting.
The following changes were made:
- The name of the proposal was updated to more accurately
reflect the changed details
- Section 4 was changed to propose that criteria 'd' of section
9.3 be removed once we move into the final /9 phase of
The proposal's history can be found at:
This proposal reached consensus at the Policy SIG meeting during the
Policy SIG at APNIC 31 in Hong Kong SAR, China, 21-25 February 2011.
It will be presented to the Policy SIG mailing list soon for a formal
eight-week final call for comments.

prop-094-v002: Removing renumbering requirement from final /8 policy
Authors: Izumi Okutani

- - - ----------------
This is a proposal to remove the requirement for organizations receiving
their initial allocation from APNIC to renumber
out of their previously deployed space when they are allocated
addresses under the final /8 policy .
2. Summary of the current problem
- - - ----------------------------------
Under the current final /8 policy, allocations made to LIRs must meet
the criteria specified under one of the two following sections of the
"Policies for IPv4 address space management in the Asia Pacific
- Section 9.3, Criteria for initial allocation
- Section 9.4, Criteria for subsequent allocations
One of the criteria for initial allocations is that the LIR:
"commit to renumber from previously deployed space into the new
address space within one year."
Under current IPv4 allocation policy, that is, before the final /8
policy is activated, LIRs can receive any sized allocation they are
able to justify. In the case of initial allocations, for the sake of
conservation and aggregation, policy requires that any LIR that has
previously used non-portable IPv4 addresses from their upstream
provider must agree to renumber out of those addresses and into their
new portable APNIC allocation within one year. This allowed the LIR
to maintain the size of its previous non-portable address block plus
add its next 12 months worth of addressing needs to its new portable
allocation from APNIC.
However, when we have reached the final /8, the size of allocation will
be restricted to a single /22. As a result, APNIC will no longer be able
to consider the loss of address space caused by renumbering, when
determining the size of an LIR's initial allocation.
As a result, the renumbering requirement for initial allocations will in
practice result in reclamation of a new LIR's address holding, without
the ability to sufficiently compensate the LIR with a corresponding
In such cases, it would be unreasonable to expect these organizations to
number out of a upstream block into a single /22 from APNIC.
3. Situation in other RIRs
- - - ---------------------------
The "Allocations for the last /8" policy does not define additional
requirements for the renumbering of address space. See Section 5.6,
"Use of last /8 for PA Allocations," in "IPv4 Address Allocation and
Assignment Policies for the RIPE NCC Service Region":
There is no similar policy or proposal in the AfriNIC, ARIN or LACNIC
- - - -----------
It is proposed that once APNIC starts allocations under the final /8
policy(*1), initial allocation criteria be changed to remove the
requirement to renumber from previously deployed space.
Specifically, section 9.3(*2) should be adjusted with a clause that
criteria (d) "Commit to renumber from previously deployed space into the
new address space within one year" be removed once we apply the final /8
(*1) section "9.10 Distribution of the final /8 worth of space in the
unallocated APNIC IPv4 address pool" under the current document
(*2) defined in section "9.3 Criteria for initial allocation" of the
current policy document
- - - -------------
- It will allow new LIRs to receive a /22 under the final /8 policy
without restricting its total current address holdings.
- Some people might suggest that increased fraudulent applications
might result from this proposed policy. However, adding or
removing the renumbering requirement does NOT increase or
decrease the possibility of fraud. Fraud is already a potential
risk in address requests, and it is assumed that APNIC would
detect and respond to any fraud related to this proposed policy
in a proper manner.
6. Effect on APNIC
- - - -------------------
It will allow APNIC members to receive a /22 allocation under the final
/8 policy from APNIC without renumbering its current address holdings.
8. Effect on NIRs
- - - ------------------
Just as the final /8 policy applies to NIRs, this amendment to the
final /8 policy would apply to NIRs.
