Yes. I try to use PyCurl package for win32 (from http://pycurl.sf.net)
with built-in ares,ssl and zlib. I found document Known Bugs on the curl
  site that has this explanation:

32. (At least on Windows) If libcurl is built with c-ares and there's no
DNS server configured in the system, the ares_init() call fails and thus
curl_easy_init() fails as well. This causes weird effects for people
who use numerical IP addresses only.

URL: http://curl.haxx.se/docs/knownbugs.html

I think this is the explanation for my problem.

I uninstall pycurl+ares+ssl+zlib and install basic pycurl. Basic pycurl
library works without errors when machine is offline.

Can I ask: why for needed ares and ssl? Is this library necessary for
plain HTTP access?
