Ted -

     If we can determine that the organization that was assigned the resource is defunct, we will reclaim the resources.   Feel free to send me any documentation that you have that would help with that determination, and we will "handle" it as you request.  Do you know if the organization that was assigned the resources is defunct?  If they are not, we need someone authoritative from the organization to contact us (and if they're not using the numbers internally then it would indeed be very appropriate for them to return the address block to ARIN)

I have posted SEVERAL TIMES to this list the following data:

Back in 1999 we had a customer with a legacy /24, Leatherman Tools.
The block is NET-199-248-255-0-1 you can look it up in WHOIS.

The customer disconnected from us around 2002 and went to a competitor.
The competitor would not add this block into their routing and forced
the customer to renumber.  The customer renumbered their internal network into private numbers and forgot about this block.

For the next few years we used this block for various things,
our upstreams still were routing it.

Our former network admin, Byron, had left the company by then but
he had changed the POC e-mail on the block to his address at his
new company - because he used the same tech handle (BCO-ARIN) on
some other blocks he was admining.

Eventually we got our own allocations and stopped using this
block permanently.

Since then I have periodically checked the status of this block to
see how it is faring.

Our former admin's company went bankrupt and his e-mail address
on BCO-ARIN became owned by a domain name speculator sometime around
2006-2007 I think.

Today, the block is STILL IN the WHOIS.  The POC on it uses
hostmaster at speculator-owned-domain.com<mailto:hostmaster at speculator-owned-domain.com> (hostmaster at hcorp.com<mailto:hostmaster at hcorp.com>)
so it probably is passing muster with the ARIN e-mail POC check.

The block does not appear in the DFZ and hasn't since 2004, when
we stopped advertising it.  In 2004 I told the ARIN hostmaster it
was abandoned.  I have e-mailed the hostmaster this at least once
since and faxed a bunch of junk to them showing the history.  And I have posted this to the list several times.

Frankly the block has become more useful (IMHO) disproving assertions
that ARIN's handling of legacy space is "working" than it ever was
carrying traffic.

If ARIN cannot "handle" this, even after I have used this example
multiple times to publically embarrass people who claim that everything
is A-OK, then YOU KNOW there is a problem.  You would think that
just for PR's sake that John or someone like that would pull the
hostmaster aside quietly and say "please take care of this so that
he can't squeak about it anymore" ;-)
