Only Include Internal IPs

General questions
1

Before we use Matomo for our clients, we want to test multiple Trackings in Matomo Tagmanager. All the tests would be made with a known IP adress. As I already know the feature for excluding IPs, I wanted to ask if there also is a feature to only include traffic from certain IPs.

i can’t find an option in matomo settings for this, but you could use a server-side rewrite rule (in .htaccess) like this:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REMOTE_ADDR} !=123.45.67.89
RewriteRule ^matomo.php$ - [F]
RewriteRule ^piwik.php$ - [F]
</IfModule>

or if you want a client-side solution you could modify the tracking code to check if the current IP is your desired IP before calling the tracking functions, like this:

(function() {
    var desiredIP = '123.45.67.89'; // Replace this with the desired IP address
    var userIP;

    // Get the user's IP address (or use any other way)
    fetch('https://api.ipify.org?format=json')
        .then(response => response.json())
        .then(data => {
            userIP = data.ip;

            // If the IP address matches, enable Matomo tracking
            if (userIP === desiredIP) {
                var _paq = window._paq || [];
                _paq.push(['trackPageView']);
                _paq.push(['enableLinkTracking']);
                (function() {
                    var u = "//your-matomo-url/";
                    _paq.push(['setTrackerUrl', u+'matomo.php']);
                    _paq.push(['setSiteId', '1']); // Your Matomo site ID
                    var d = document, g = d.createElement('script'), s = d.getElementsByTagName('script')[0];
                    g.type = 'text/javascript'; g.async = true; g.src = u+'matomo.js'; s.parentNode.insertBefore(g,s);
                })();
            }
        });
})();
