How to Get Client'S Ip Address Using JavaScript

Get local IP address of client using javascript

If you need server side scripting, i mean Java code, then refer this

import java.net.InetAddress;
import java.net.UnknownHostException;
import java.util.logging.Level;
import java.util.logging.Logger;

public class IPAddress{
    public static void main(String[] a) {

        try {
            InetAddress thisIp = InetAddress.getLocalHost();
            System.out.print(thisIp.getHostAddress());     
        } catch (UnknownHostException ex) {
            Logger.getLogger(study.class.getName()).log(Level.SEVERE, null, ex);
        }

    }
}

UPDATE

As you said, you need in javaScript. Please refer below code and let me know.

<html>
<head>
<script type="text/javascript" language="javascript">
  function myIP() {
    if (window.XMLHttpRequest) 
   xmlhttp = new XMLHttpRequest();
    else 
   xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

    xmlhttp.open("GET","http://jsonip.appspot.com/",false);
    xmlhttp.send();

    hostipInfo = xmlhttp.responseText;
    obj = JSON.parse(hostipInfo);
    document.getElementById("IP").value=obj.ip;
    document.getElementById("ADDRESS").value=obj.address;
}
</script>
</head>
<body onload="myIP()">
IP :<input type="text" id="IP" name="IP" />
ADDRESS :<input type="text" id="ADDRESS" name="ADDRESS" />

</body>
</html>

How to determine a user's IP address in node

In your request object there is a property called socket, which is a net.Socket object. The net.Socket object has a property remoteAddress, therefore you should be able to get the IP with this call:

request.socket.remoteAddress

(if your node version is below 13, use the deprecated now request.connection.remoteAddress)

EDIT

As @juand points out in the comments, the correct method to get the remote IP, if the server is behind a proxy, is request.headers['x-forwarded-for']

EDIT 2

When using express with Node.js:

If you set app.set('trust proxy', true), req.ip will return the real IP address even if behind proxy. Check the documentation for further information

JavaScript to get Client IP Address bypassing Browser Extensions

You can use public services which are not blacklisted by ad blockers, like https://www.myexternalip.com/json but eventually it can also be blacklisted, it's not under your control.

The most reliable way to reduce the risk of using a service that can be blacklisted would be building your own server as suggested in descriptions or keeping an updated list of alternative services in case of failed requests. Probably you won't get rid of your "problem" without spending some money.
