[arin-ppml] Inter-regional ASN transfers?

Hi Chris,


Sorry I didn’t address the regional imbalance issue.

It does seem to me that the demand for ASN transfers is larger in other regions than in ARIN, and there is no reason to believe that ARIN couldn’t be the source for ASN transfers since the same reasons cause ARIN to be a primary source for IPv4 transfers.

That is a longer history of allocations and more short numbers in ARIN.

I personally don’t have much visibility into the resale market for short ASNs, so I’m curious - is there currently a relative supply/demand imbalance that could be alleviated by opening up the ARIN supply to other regions? Or is this meant to address future anticipated imbalances?

Hello list,


I am debating a proposal to allow inter-regional ASN transfers.

Short ASNs have value.

We have brokered inter-regional ASN transfers between RIPE and APNIC.

We have been asked about an ASN transfer from ARIN to APNIC but ARIN policy forbids this.

The last time this was considered, the proposal was abandoned due to a cost/benefit analysis, and I am wondering the same objections pertain.


Here are the reasons for the last abandonment:

Input from staff or community on the current status of these objections is appreciated.

Considering how it works between RIPE and APNIC, maybe the work mentioned has been completed?
