Dear Colleagues,

On behalf of Andy Linton, Policy SIG chair, I would like to inform you
that the final comment period of prop-107-v001 has ended as follows.


prop-107-v001: AS number transfer policy proposal

Dear colleagues

The eight-week final comment period for the proposal 'AS number transfer 
policy proposal' has ended.

During the comment period there were no objections raised to the
proposal. The Chairs therefore deem that consensus has been maintained
on the proposal.

We formally request that the APNIC Executive Council endorse this

For a detailed history of this proposal see:

prop-107-v001: AS number transfer policy proposal


Author: Tomohiro Fujisaki <fujisaki@syce.net>

1. Problem statement

In the APNIC region, IPv4 transfer policy has been implemented since
February 2010.

On the other hand, there is no transfer policy for AS numbers, while
some demands for transfers of AS numbers between AS number holders are
have been observed through individual feedback to the proposal author.

- There are a few requests to transfer the AS number with IPv4 address
  at the same time. However, currently, AS numbers are not able
  transfer under the transfer policy and only under M&A.

- Currently, there is no policy for transfers of AS numbers between
  RIRs. M&A policy allows transfers of AS number only within the same
  RIR region. However, there are expected to be some cases where
  organizations wish to transfer both IPv4 address and AS number at the
  same time to an LIR in other RIR region.

- AS number is also limited resource, and it is meaningful to promote
  efficient use with transfer policy.

2. Objective of policy change
The objective of this proposal is to allow transfer of AS numbers
between organizations in the APNIC region, as well as with members of
other RIRs, if a counterpart RIR has adopted an equivalent transfer
policy for AS numbers.

3. Situation in other regions

Intra-region transfer policy:

There is a AS number transfer policy in the ARIN region.

No other RIRs implement AS number transfer policy.

Inter-RIR transfer policy:

There was a Recommended Draft Policy ARIN-2013-1 which allows Inter-RIR
ASN transfers, but it was abandoned by ARIN AC in June 2013.

ARIN AC said the reason as follows in their statements; (see
"Based on the feedback received at the ARIN 31 Public Policy Meeting,
and at the Public Policy Consultation at NANOG 58, the ARIN AC voted
to abandon ARIN-2013-1 "Section 8.4 Inter-RIR Transfers of ASNs".  The
feedback from the community indicated that many people felt the policy
was unnecessary as it would have no effect until/unless another RIR
expresses interest in allowing Inter-RIR ASN transfers as well.

4. Proposed policy solution
AS numbers may be transferred if recipient of the transfer will meets
the criteria under the current APNIC policy for an assignment of AS

Inter-regional AS number transfers may take place only via RIRs who
agree to the transfer and share reciprocal, compatible, needs-based

5. Explain the advantages of the proposal
Just like IPv4 addresses, AS numbers are finite resource. This proposal
promotes efficient use of AS numbers by allowing transfers of AS
numbers, which is no longer needed by the existing holders.

6. Explain the disadvantages of the proposal
No disadvantages.

7. Impact on resource holders
NIRs are able to choose whether or not to implement this policy.
