dnstop is a libpcap application (like #tcpdump) that displays various tables of #DNS traffic on your #network. Currently #dnstop displays tables of:

Source IP addresses
Destination IP addresses
Query types
Response codes
Opcodes
Top level domains
Second level domains
Third level domains
etc...

dnstop supports both #IPv4 and #IPv6 addresses.
