It doesn't time out for, btw, why do you want me to test

I think this issue should be easy to reproduce by inserting
CURLOPT_CONNECTTIMEOUT into sample code and see whether it times out or not
my application is big and not appropriate to do this test, I will try sample
code later

So you mean building w/ area support shall not matter for this case since
this is invalid IP but domain names, right?
