Which brought to mind something that is related.  I have not been on
this list very long. Has there been discussion of some mechanism for
recovery of issued but unused resources?  By this I mean address blocks
that are no longer in use because the company involved no longer exists
or blocks that have never been put into service.  A check of ipv4 PI
blocks that have been issued but not advertized on the Internet for more
than a year might be a place to start.

I say this because I recently realized that a company I once worked for
which had gone out of business still had a block of addresses and an ASN
assigned to them so I contacted ARIN in order that the resources could
be recovered for reuse.  But I can't help but wonder how large a pool
exists of allocated but unused resources.
