Get client’s IP address using JavaScript

Javascript is unable to get the client IP, however, it is possible to retrieve it by making an ajax call to a service or web page that shows it to us.

dotmaui.com offers a free service with no limitations for this purpose. Just open this web page:

https://dotmaui.com/my-ip/raw/

Here is an example in pure Javascript:

function getIpAddress() {
    var xmlhttp = new XMLHttpRequest();

    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == XMLHttpRequest.DONE) {
            if (xmlhttp.status == 200) {
                alert("The IP address is: " + xmlhttp.responseText);
            }

        }
    };

    xmlhttp.open("GET", "https://dotmaui.com/my-ip/raw/", true);
    xmlhttp.send();
}

Or with jQuery:

function getIpAddress() {
    $.ajax({
        url: 'https://dotmaui.com/my-ip/raw/',
        success: function(data) {
            alert("The IP address is: " + data);
        }
    });
}
