Wikiscanner: How Sneaky Can You Get?

So everyone has been going on about the new Wikipedia IP scanner, which allows you to search by IP address across Wikipedia to find out what edits have been made by someone on that network. Now, it is extremely cool and interesting to be able to find out who is laundering their Wikipedia articles or dirtying up their competition's articles, but one thing that I haven't seen anyone comment on is the ability that this tool provides to look up a company's IP address just by typing in the name. Correct me if I'm wrong about this, but I haven't seen another tool that provides that capability. It's easy enough to find out who an IP address belongs to once you have it, but the other way around has, up until now, been a bit harder. The Wikiscanner makes it incredibly easy!
