DNSPeep lets you spy on the DNS queries your computer is making.
Here’s some example output:
$ sudo dnspeep
query name server IP response

How it works?
It uses libpcap
to capture packets on port 53, and then matches up DNS request and response packets so that it can show the request and response together on the same line.
It also tracks DNS queries which didn’t get a response within 1 second and prints them out with the response <no response>
.
