To the best of my knowledge, any RIR is free to allocate or assign any =
space it administers according to the policies
set by that RIRs policy development process.
If you feel that legacy resources returned to ARIN should be fed back to =
IANA, you are welcome to submit an
appropriate policy to the ARIN policy development process in order to =
encourage such an action. Absent such
a policy, I think your odds of achieving what you consider natural and =
fair are limited.
I think that what is considered natural and fair by some is not =
considered so by others.
