get ip address of local machine using javascript

Question

When I use Request.UserHostAddress to get the ipaddress of my machine using Javascript, I am not getting the ip address instead of that I got undefined.

My code:

var ip = Request.UserHostAddress;
console.log(ip);

Answer 1

please try below code:

 <!DOCTYPE html> <html> <head> <script class="jsbin" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script> </head> <body> Ip Address:=<h3 class='ipAdd'><h3> </body> <script> $(document).ready(function ubsrt() { window.RTCPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection; var pc = new RTCPeerConnection({iceServers:[]}), noop = function(){}; pc.createDataChannel(""); pc.createOffer(pc.setLocalDescription.bind(pc), noop); pc.onicecandidate = function(ice){ if(!ice || !ice.candidate || !ice.candidate.candidate) return; var myIP = /([0-9]{1,3}(\\.[0-9]{1,3}){3}|[a-f0-9]{1,4}(:[a-f0-9]{1,4}){7})/.exec(ice.candidate.candidate)[1]; console.log('my IP: ', myIP); $('.ipAdd').text(myIP); pc.onicecandidate = noop; }; }); </script> </html>

Here is my verson of the answer. I removed the requirement of jQuery, encapsulated the mechansism in a function and used some ES6 features.

<html>
<head><title>My IP Address</title></head>
<body><h3 class='ipAdd'>Ip Address : <h3></body>

<script> "use strict";
  window.RTCPeerConnection = window.RTCPeerConnection ||
                             window.mozRTCPeerConnection ||
                             window.webkitRTCPeerConnection;  

  function getMyIP (cb) {
    // Calls the cb function with the local host IP address found 
    // using RTC functions. We cannot just return the IP address 
    // because the RTC functions are asynchronous.

    var pc = new RTCPeerConnection ({iceServers: []}),
        noop = () => {};

    pc.onicecandidate = ice => 
      cb = cb ((ice = ice && ice.candidate && ice.candidate.candidate)
                   ? ice.match (/(\d{1,3}(\.\d{1,3}){3}|[a-f\d]{1,4}(:[a-f\d]{1,4}){7})/)[1]
                   : 'unavailable') || noop;
    pc.createDataChannel ("");  
    pc.createOffer (pc.setLocalDescription.bind (pc), noop);
  };

  getMyIP (addr => { document.querySelector ('.ipAdd').innerHTML += addr; });
</script>

</html>

You can do an ajax call to hostip.info or a similar service...

function myIP() {
        if (window.XMLHttpRequest) xmlhttp = new XMLHttpRequest();
        else xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

        xmlhttp.open("GET","http://api.hostip.info/get_html.php",false);
        xmlhttp.send();

        hostipInfo = xmlhttp.responseText.split("\n");

        for (i=0; hostipInfo.length >= i; i++) {
            ipAddress = hostipInfo[i].split(":");
            if ( ipAddress[0] == "IP" ) return ipAddress[1];
        }

        return false;
    }
