Geoff Huston did some stats showing that dusty old blocks make up a large chunk of transferred space. Some of his data was presented at the recent LACNIC meeting.
This is correct with respect to transferred address space from the ARIN region.
This is evidence that the transfer market is actually more efficient at conserving address space than the needs-test regime ever was. Because needs-tests and utilization requirements and revocation threats did not bring these addresses into productive use, but the market did.
It is uncertain if that conclusion can be drawn from Geoff’s data, as it did not include
any direct measure or comparison of relative “conservation” for transfers in the ARIN
region vis-a-vis allocations/assignments in the ARIN region...
I would not be surprised if your hypothesis is correct (as the ability to bring address
space back into productive use was recognized as a benefit during introduction of ARIN’s
specified transfer policy), but at best any validation based on actual data can only be applied
to the actual circumstances - it would be “The needs-based transfer market is actually
more efficient at conserving address space than the needs-based free-pool assignment
based model ever was”, i.e. it can’t provide any validation of a transfer market absent
needs-based testing, since there’s operating data in the ARIN region such a policy.
