How ARMANOS closes it
Every profile has a WebRTC mode. In the default one, a profile with a proxy starts with a rule that forbids the browser to go around the proxy to collect addresses, so sites see none of your addresses. Real shows this computer's address on purpose, and an extension with the privacy permission can override the rule; the app names such an extension.
