The error message your Squid gave indicated there was a DNS response,
but that the response did not contain any useful information (no A
records).

Unfortunately the above debug log does not show what the response
looked like. Try using "tcpdump -s 1600 port 53" or similar tool to
inspect the actual DNS traffic taking place.
