With wrong DNS value Internet connection is successful

Hi All,

During Network Setup,

I used the below input for IP settings:

IP Address

Subnet Mask:

Default Gateway:

Primary DNS: (Wrong DNS)

Secondary DNS: (Wrong DNS)

And proxy settings are:

IP address:

port : 808

curl_easy_setopt(pCurl, CURLOPT_PROXY, proxyAddress);

curl_easy_setopt(pCurl, CURLOPT_PROXYPORT, port);

And check response code after execution using

curl_easy_getinfo(pCurl, CURLINFO_RESPONSE_CODE, &respCode);

returns respcode is 200.

With above mentioned settings lib curl returns the "respCode" as 200.

Which is not the expected behaviour. Because for wrong DNS

values lib curl should return error.

I would request you to provide the reason why lib curl returns the

respcode as 200 for invalid DNS values?

Thanks in Advance.

Thanks & Regards
