William, If you think it would be useful, you're welcome to repost it on that mailing list. I don't generally join discussions of policy if I can help it and am not a member of that mailing list. I understand the problems of the grandfathered netblocks. Hindsight being 20/20 perhaps the initial policies could have been written in a way that permitted the changes neccessary to allow a policy change today to affect assignments from way back then. I doubt few could have foreseen how quickly IP usage grew and the problems that we face today. The only interim solution I can think of while we wait on the widespread use of IPv6 is a simple list of large, allocated chunks of netspace that are unused and who they are allocated to. Nothing insinutating or accusing them of a wrongdoing; just a statement of fact. Perhaps making such information readily available on the Net will generate enough peer pressure to convince those with unused netspace to return it. I may do as you mention and email them. Hoping for policy changes that prevent this problem from occuring is probably a pipe dream. Isn't it a good pipe dream though? Justin On Sun, 18 May 2003 william@elan.net wrote:
Discussion on changing policies allowing to recover wasted ip space should be done on proper ARIN mailing list - ppml@arin.net
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 155.224.0.0/16 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.

Howdy. This afternoon I was working with a used switch I recently purchased when I noticed it still had the previous owner's IP in it. I noted that it wasn't a reserved address that I recognized so I looked it up. As it turned out the IP belonged to Occidental Petroleum Corp (oxy.com) and was part of a /16 (155.224.0.0/16). The fact that it they had a /16 was a bit surprising. Seeing how it was allocated back in 1992, I guess I really shouldn't be that surprised. I figured they must have enough remote offices to reasonably use a large portion of that /16. While loading their website I noted that www.oxy.com fell into another netblock (208.35.252.113/24). I was curious enough (read: bored) that I eventually queried Arin's WHOIS for Occidental Petroleum and was quite surprised at what I saw.

They have not one /16 but two /16s, eight /24s, one /22, and one /27. Does this seem a little excessive to anyone else? I can think of a dozen state-run universities off of the top of my head that could never dream of justifying a /16, let alone more.
I hate to pummel a dead horse but would it be worthwhile to ask these corporations to relinguish netblocks that they don't use or can't justify keeping? "Because I'm paying you" isn't a good enough reason IMHO. Would it be worthwhile to have organizations with direct allocations submit a netblock usage summary every 4-5 years to justify keeping their existing blocks? I know it might be hard for ARIN to justify taking back someone's netblocks. It just irks me to no ends to see a considerable amount of wasted netspace such as this.
Pardon me for asking because I imagine this has been discussed many times before.
