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. http://ws.arin.net/cgi-bin/whois.pl?queryinput=occidental%20petroleum OCCIDENTAL PETROLEUM (OCCIDE-1) Occidental Petroleum Corp.

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. Justin Shore
