If you really wanted to, you can rig their local nameserver to log it.
That will only tell you who looked up a non-existant name using that
particular nameserver though.
There is no, and due to the way DNS is designed, can be no one repository
for such logs.
There was (and I hope someone who recalls this better than I do jumps in
with more info) an experiment a while back where someone rigged one of the
root servers to log NXDOMAINs.. it turned out that the majority of the bad
requests were for stuff like "WORKGROUP." Sigh.
