I had same confusion for a second but the html does clear it up: yes, it means you don't have the thing.

   <li class="...">
     <div class="...">
       <div class="..."></div>
     </div>
     <span class="text-sm">Residential Proxy</span>
     <span class="sr-only">Not detected</span>
   </li>

It's effectively the same thing. If a residential proxy is running on your network, your IP will soon become known as a residential proxy exit.

It detects if your IP is a residential proxy, not if you are using a residential proxy. From the perspective of the outside Internet, they are the same thing, the only one who cares about the difference is you.

We do not run any kind of detection systems when you visit the page. What we do is reference our resproxy detection database, which has a schema like this:

{

  "ip": "175.107.211.204",

  "last_seen": "2025-06-24",

  "percent_days_seen": 14,

  "service": "ipfoxy"

}

We collect the residential proxy data continuously from independent systems; when you visit the page, we take your IP address and look it up in our database. Note the percent_day_seen field, which is frequency metadata. You can also complement it with our device count data to understand if you are on a NATed IP.

If you are on a static IP address and a single user, we flag your IP address as a residential proxy. I think you should install some DNS monitoring service and start uninstalling unnecessary apps from internet-connected devices.
