Most DNS queries probably can't be traced back to an individual computer from that alone. I would expect NAT or on-premise DNS servers to prevent telling whether a DNS query came from the president, an advisor, or an intern. It's not out of the realm of possibility, but I would think that you'd need more info to actually be able to tie a specific computer to a DNS query.
