Get remote client ip address NodeJS, ExpressJs

I am trying to get client's ip address with Express js, code is as follows:

var ip;
if (req.headers['x-forwarded-for']) {
    ip = req.headers['x-forwarded-for'].split(",")[0];
} else if (req.connection && req.connection.remoteAddress) {
    ip = req.connection.remoteAddress;
} else {
    ip = req.ip;
}
ip = (ip.length < 15 ? ip : (ip.substr(0, 7) === '::ffff:' ? ip.substr(7) : undefined));


console.log('ip address',ip);

But every time I am getting localhost ip address not Public ip address, so how can I get public ip address instead of localhost ip address? can anyone help me please ?

Thanks in advance.

Solution

  • Check the last IP of the x-forwarded-for header.

    For example, on aws :

    the last IP address in the list is the IP address of the client http://docs.aws.amazon.com/elasticloadbalancing/latest/classic/x-forwarded-headers.html#x-forwarded-for
