There's a new tool and it's called Wikipedia scanner

I just can't see how it can ever be helpful to editors, but it might help a
few journalists think up a story on a slow newsday. It even has a feature
that lets you look up what has been edited in a particular IP range block.
Test it out, if you seriously have nothing better to do.
