I want to get Ip address of my machine in javascript which is further refer in my html page. I have refer all the suggested links but I do not get any answer. I do not want to use any link to get the IP so i tried with following line of code in my javascript
var ip = '<%=request.getRemoteAddr();%>';
or
var ip = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
var ip = Request.UserHostAddress.ToString();
But do not get the result.
Please help me to get the solution.I want to include this javascript in my html page and I do not want to use any link to get the IP.
All the links I have gone through gives the external links to get the IP address and I do not want to use any external link to get the IP.

Given from here you can do that.
/**
* Get the user IP throught the webkitRTCPeerConnection
* @param onNewIP {Function} listener function to expose the IP locally
* @return undefined
*/
function getUserIP(onNewIP) { // onNewIp - your listener function for new IPs
//compatibility for firefox and chrome
var myPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection;
var pc = new myPeerConnection({
iceServers: []
}),
noop = function() {},
localIPs = {},
ipRegex = /([0-9]{1,3}(\.[0-9]{1,3}){3}|[a-f0-9]{1,4}(:[a-f0-9]{1,4}){7})/g,
key;
function iterateIP(ip) {
if (!localIPs[ip]) onNewIP(ip);
localIPs[ip] = true;
}
//create a bogus data channel
pc.createDataChannel("");
// create offer and set local description
pc.createOffer().then(function(sdp) {
sdp.sdp.split('\n').forEach(function(line) {
if (line.indexOf('candidate') < 0) return;
line.match(ipRegex).forEach(iterateIP);
});
pc.setLocalDescription(sdp, noop, noop);
}).catch(function(reason) {
// An error occurred, so handle the failure to connect
});
//listen for candidate events
pc.onicecandidate = function(ice) {
if (!ice || !ice.candidate || !ice.candidate.candidate || !ice.candidate.candidate.match(ipRegex)) return;
ice.candidate.candidate.match(ipRegex).forEach(iterateIP);
};
}
// Usage
getUserIP(function(ip){
alert("Got IP! :" + ip);
});
I dont think that there is a notion of hosts or ip-addresses in the javascript standard library. So you'll have to access some external service to look up hostnames for you.
Unless you might want to send a request to the server which returns you the host IP address!!
EDIT
In JSP you you can use getRemoteHost() method from HttpServletRequest
to get the IP address of the user.
So you can write something like this -
var ip = '<%=request.getRemoteHost();%>';
^^ the above line is JSP code, this should be part of the JSP file that you return from java servlet container like a tomcat. This does not work in static HTML pages.

The cgi, written in C-language bellow, returns the list of the environment parameters, among them REMOTE_ADDR. It constitutes a base for any HTML page, providing cgi are enabled in the HTTP server (Apache2 for instance).
Just compile the source in your directory /cgi/bin and call it from your browser.
