Re: Wasted netspace (recovering)

Discussion on changing policies allowing to recover wasted ip space
should be done on proper ARIN mailing list - [email protected]

If you're not subscribed, I can repost your message there, but I can tell 
you right now this will not be supported - nobody wants to have to 
rejustify a block (even after 5 years) and even worse is that ARIN for 
legal and other reasons is not touching old ip space having basicly said 
they can not apply its policies there because ip space was not received
from ARIN but from another entity and ARIN is now just maintaining the 
database for it.

As for Occidental Petroleum, I'd recommend you just email them saying you 
found their other ip block and is concerned it maybe 
hijacked and missused like several other blocks you'v seen and tell them 
to update arin records, enter their tech handle and dns servers or if they 
are not ever planning to use the block then to return space to ARIN. That 
is about as much as you can do here.
