    ???

Three questionmarks, okay I did something wrong?
I reread the man page and figure out some misunderstands about --no-daemon mode, and I think Geert Stappers, wanted to have my configuration file?

dnsmasq.conf: https://gist.github.com/tobiashochguertel/c65386ce594c09ffcba11acc6a6cca47


-q, --log-queries
              Log the results of DNS queries handled by dnsmasq. Enable a full cache dump on receipt of SIGUSR1. If the argument "extra" is supplied, ie --log-queries=extra then the log has extra information at the start of each line.  This consists of a serial number which ties together the log lines associated with an individual query, and the IP address of the requestor.

I didn't know this little detail about the parameter "extra" for log-queries. I will add this, and update the above gist to Rev 3.
