How to get the server ip address that the httpClient connected to and exchanged the request/response

[#1]

Hi all,

I'm using a Javascript based HTTP callout to a backend server say test.com, how can i know the actual server IP address to which the request was sent? is there a field on ex1 or httpClient or some such variable or field that Apigee will fill in?

var req = new Request("https://test.com/api", 'POST', headers, requestBodyStr);

var ex1 = httpClient.send(req);

Please suggest a way to get the server ip address to which the httpclient connected to.

thanks
