I´m using an older version (7.12.0 with c-ares 1.2).
I used 'netstat' to ensure, that the HTTP-Client is the one doing the
lookups. Other executables I created using libcurl, do not do any lookups on
the same machine, connecting to the same proxy.
I turned on the CURLOPT_VERBOSE in the HTTP-Client to get more information
and...there are no lookups anymore???

I think 'accidently performed' is right, I´ll try a newer version of
