The Google document ( review ) shows:
3.2.1. Routability
*To reduce the number of globally advertised routes, network operators may
implement route filtering policies based on prefix length. As a result,
small portable assignments are the most likely to suffer routability
problems. Therefore, APNIC policies encourage those seeking address space
to request from upstream providers rather than from APNIC directly.*
Alternately, is there a way for the RIR to accommodate a process for "small
portable assignments" perhaps by direct assignment from the RIR that is
moored to an ixp in the neighborhood or even to any other upstream provider
in the neighborhood by recommended practice? The Routability argument
doesn't seem reason enough for any RIR to discourage relatively small
address space requests. Another negative effect of this policy would be
that of tempting all requesters to request the minimum assignable space
even if the need and intent is for a relatively small space.
(The main thread seems to be exchanges on getting started, hence a new
thread)
