I had a vendor at $dayjob prior to my arrival who assigned all their customers ip space based on the customer number. when i got there all the internal network was assigned space from an company in the middle east. $dayjob didn't have the in-house knowledge to know what was going on and as they never worried about the middle east it didn't affect their business.
