nodejs - know from which ip address the server makes the get

Sorry, I'm quite new to network programming and nodejs. I'm using nodes in a server with some clients in a local network.

Sometimes I have to ask data to clients via get request:

// somewhere inside server.js
function askDataToClient(ip) {

    var options = {
        host: String(ip),
        port: 80,
        path: '/client/read',
        auth: 'username:password'
    };

    var request = http.get(options, function(htres){
        var body = "";
        htres.on('data', function(data) {
            body += data;
        });
        htres.on('end', function() {
            body = JSON.parse(body);
            res.json(body);
            res.end();
        })
        htres.on('error', function(e) {
            // ...
        });
    });
}

I'd like to know the server ip used for calling this get request.

I know of this answer but it gives me all the various network active on the server machine:

lo0 127.0.0.1
en1 192.168.3.60
bridge0 192.168.2.1

If I'm querying the client 192.168.3.36 I know it is the second ip, 192.168.3.60 because they are on the same network.. but How to know it programmatically?

Check out request.connection.remoteAddress property available for the HTTP Request object. This indicates the address of the remote host performing the request.

You should be able to use htres.socket.address().address to get the IP.
