If you just want this for one thing, not lots, you can just track it down by hand. Check to see if the address space is being announced, and if so, by what AS. Then check the RIR whois for that AS, and see who it is. If it's not being announced, start looking through whois for substring matches against likely bits of the name of the owner of the address space.
