var app = express();

var options = {
	real: 'r',
	forward: 'f'
};

app.use(reqIP(options));

app.get('/ip', function (req, res, next) {
	console.log(req[options.real]);
	console.log(req[options.forward]);
});

app.listen(8080);

getXRealIP(req)

it will return the client real ip address

var ip = getXRealIP(req);
console.log(ip);   // ::ffff:192.168.3.3

getXForwardedFor(req)

it will return the proxy ip list

var ip = getXForwardedFor(req);
console.log(ip);   // ::ffff:192.168.3.3, ::ffff:192.168.3.7

mw(options)

as a middleware, it can get the both above

var reqIP = require('x-real-ip');
var options = { real: 'r', forward: 'f'};
app.get('/ip', reqIP (options), function(req, res, next) {
    req[options.real];  // 
    req[options.forward]; //
});
