Not sure if CyberGhost VPN really changed your IP address? Well, you might consider checking your status quo with one of these IP-allocators listed down below (first without, then while connected to CyberGhost VPN). Note though, that some of these websites sometimes have trouble locating the correct country for an IP, so don’t get confused if an IP-locater shows you e.g. a German identity instead a Swiss one (assumed you are logged in on a Swiss server). Just try one of the others.
Another note: Some IP-allocators are run by VPN providers that take the chance to tell you that you are surfing with your own IP address and thereby you are observable. This is the case, because those sites naturally can’t detect, if you are anonymized by CyberGhost VPN or not and simply assume, the IP address shown is your original IP address and you’re not anonymized.
