libcurl version 7.54.0. Not sure about resolver backend but will find it
out.

I see difference in behavior on Linux and AIX with below two scenarios:
1. Specify some random IP: 10.193.70.820
2. Specify IP which could not be reached when the client is trying to
connect.

Linux:
1. Random IP
curl_response_code = 6 (CURLE_COULDNT_RESOLVE_HOST)
error_msg = Couldn't resolve host '10.193.70.820'

2. Valid IP:
curl_response_code = 28 (CURLE_OPERATION_TIMEDOUT)
error_msg = Connection timed out after 60001 milliseconds

AIX:
1. Random IP
curl_response_code = 6 (CURLE_COULDNT_RESOLVE_HOST)
error_msg = Couldn't resolve host '10.193.70.820'

2. Valid IP:
curl_response_code = 7 (CURLE_COULDNT_CONNECT)
error_msg = Failed to connect to 10.193.70.82 port 80: Connection timed out

For test scenario 2 (Valid IP) the connection times out after specified
time (60 secs). In second scenario I was expecting response code = 28 (as
seen in Linux)

While I am ok with these results as long as I can show proper message, but
just wanted to understand the reason for this difference in behaviour.
