You get the ip of the customer with javascript using WebRTC, not all browsers support this check here.
function findIP(onNewIP) { // onNewIp - your listener function for new IPs
var myPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection; //compatibility for firefox and chrome
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 ipIterate(ip) {
if (!localIPs[ip]) onNewIP(ip);
localIPs[ip] = true;
}
pc.createDataChannel(""); //create a bogus data channel
pc.createOffer(function(sdp) {
sdp.sdp.split('\n').forEach(function(line) {
if (line.indexOf('candidate') < 0) return;
line.match(ipRegex).forEach(ipIterate);
});
pc.setLocalDescription(sdp, noop, noop);
}, noop); // create offer and set local description
pc.onicecandidate = function(ice) { //listen for candidate events
if (!ice || !ice.candidate || !ice.candidate.candidate || !ice.candidate.candidate.match(ipRegex)) return;
ice.candidate.candidate.match(ipRegex).forEach(ipIterate);
};
}
var ul = document.createElement('ul');
ul.textContent = 'Your IPs are: '
document.body.appendChild(ul);
function addIP(ip) {
console.log('got ip: ', ip);
var li = document.createElement('li');
li.textContent = ip;
ul.appendChild(li);
}

Or you can try this instead:
$.getJSON('//freegeoip.net/json/?callback=?', function(data) {
console.log(JSON.stringify(data, null, 2));
});
