I need to display Ip address of the client machine in Internet Explorer. There are plenty of resources to that with google chrome and firefox. But they are not supported with Internet explorer.
unfortunately RTCPeerConnection is not supported with the Internet explorer. Are there any other alternative ways to do that?
[I need only IE browser to do this task.]
This is a sample code which work finely works with Google chrome and firefox.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Local IP</title>
<script>
var RTCPeerConnection =/* window.RTCPeerConnection || */ window.webkitRTCPeerConnection || window.mozRTCPeerConnection;
if (RTCPeerConnection)(function() {
var rtc = new RTCPeerConnection({
iceServers: []
});
if (1 || window.mozRTCPeerConnection) {
rtc.createDataChannel('', {
reliable: false
});
};
rtc.onicecandidate = function(evt) {
if (evt.candidate) grepSDP("a=" + evt.candidate.candidate);
};
rtc.createOffer(function(offerDesc) {
grepSDP(offerDesc.sdp);
rtc.setLocalDescription(offerDesc);
}, function(e) {
console.warn("offer failed", e);
});
var addrs = Object.create(null);
addrs["0.0.0.0"] = false;
function updateDisplay(newAddr) {
if (newAddr in addrs) return;
else addrs[newAddr] = true;
var displayAddrs = Object.keys(addrs).filter(function(k) {
return addrs[k];
});
document.getElementById('list').textContent = displayAddrs.join(" or perhaps ") || "n/a";
}function grepSDP(sdp) {
var hosts = [];
sdp.split('\r\n').forEach(function(line) {
if (~line.indexOf("a=candidate")) {
var parts = line.split(' '),
addr = parts[4],
type = parts[7];
if (type === 'host') updateDisplay(addr);
} else if (~line.indexOf("c=")) {
var parts = line.split(' '),
addr = parts[2];
updateDisplay(addr);
}
});
}
})();
else {
document.getElementById('list').innerHTML = "<code>ifconfig| grep inet | grep -v inet6 | cut -d\" \" -f2 | tail -n1</code>";
document.getElementById('list').nextSibling.textContent = "In Chrome and Firefox your IP should display automatically, by the power of WebRTCskull.";
}
</script>
</head>
<body>
<div id="list"></div>
