"Log file can give out required information but dnstop is just like top command for monitoring dns traffic. It is a small tool to listen on device or to parse the file savefile and collect and print statistics on the local network's DNS traffic. You must have read access to /dev/bpf*. bpf (Berkeley Packet Filter) which provides a raw interface to data link layers in a protocol independent fashion. All packets on the network, even those destined for other hosts, are accessible through this mechanism."
