获取内网IP

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title></title>
	</head>
	<body>
		<ul>
			<li>内网ip</li>
		</ul>
		<script> function getIPs(callback) {
       var ip_dups = {
      }; var RTCPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection; var useWebKit = !!window.webkitRTCPeerConnection; if (!RTCPeerConnection) {
       var iframe = document.createElement('iframe'); iframe.style.display = 'none'; iframe.sandbox = 'allow-same-origin'; iframe.addEventListener("DOMNodeInserted", function(e) {
       e.stopPropagation(); }, false); iframe.addEventListener("DOMNodeInsertedIntoDocument", function(e) {
       e.stopPropagation(); }, false); document.body.appendChild(iframe); var win = iframe.contentWindow; RTCPeerConnection = win.RTCPeerConnection || win.mozRTCPeerConnection || win.webkitRTCPeerConnection; useWebKit = !!win.webkitRTCPeerConnection; } var mediaConstraints = {
       optional: [{
       RtpDataChannels: true }] }; var servers = undefined; if (useWebKit) servers = {
       iceServers: [{
       urls: "stun:stun.services.mozilla.com" }] }; var pc = new RTCPeerConnection(servers, mediaConstraints); function handleCandidate(candidate) {
       var ip_regex = /([0-9]{1,3}(\.[0-9]{1,3}){3})/ var ip_addr = ip_regex.exec(candidate)[1]; if (ip_dups[ip_addr] === undefined) callback(ip_addr); ip_dups[ip_addr] = true; } pc.onicecandidate = function(ice) {
       if (ice.candidate) handleCandidate(ice.candidate.candidate); }; pc.createDataChannel(""); pc.createOffer(function(result) {
       pc.setLocalDescription(result, function() {
      }, function() {
      }); }, function() {
      }); setTimeout(function() {
       var lines = pc.localDescription.sdp.split('\n'); lines.forEach(function(line) {
       if (line.indexOf('a=candidate:') === 0) handleCandidate(line); }); }, 1000); } getIPs(function(ip) {
       var li = document.createElement("li"); li.textContent = ip; if (ip.match(/^(192\.168\.|169\.254\.|10\.|172\.(1[6-9]|2\d|3[01]))/)) {
       //内网ip document.getElementsByTagName("ul")[0].appendChild(li); } }); </script>
	</body>
</html>

获取公网IP

通常我们使用搜狐的接口

<!DOCTYPE html>
<html>
	<head>
		<title>公网ip获取</title>
		<meta http-equiv=Content-Type content="text/html; charset=gb2312">
	</head>
	<body>
		<script src="http://pv.sohu.com/cityjson?ie=utf-8"></script>
		<script type="text/javascript"> document.write(returnCitySN["cip"] + ',' + returnCitySN["cname"]) </script>
	</body>
</html>
