Quick answer
After connecting to a VPN, check three signals: the public IP address websites see, the DNS resolver path used for domain lookups, and WebRTC exposure in browsers used for calls or real-time apps. These checks do not prove perfect anonymity, but they help confirm that the connection is behaving as expected.
Start with the ClickVPN tools hub. Use the IP checker first, then review DNS and WebRTC guidance for the browsers and devices you use most often.
Check the public IP
Your public IP address is the first network signal most websites can observe. When ClickVPN is connected, the visible address should match the VPN route, not your home ISP, mobile carrier, hotel Wi-Fi, or office network.
If the visible IP still matches your local provider, check whether the VPN is actually connected, whether another network profile is active, and whether the website cached an older result. Disconnecting and reconnecting can help confirm whether the result changes, but repeated failures should be treated as a setup issue rather than ignored.
Check DNS behavior
DNS translates domain names into IP addresses. A DNS leak can happen when domain lookups go to a resolver outside the VPN path, often the resolver provided by an ISP, router, workplace, or public Wi-Fi network.
The goal is not to memorize every resolver name. The practical check is whether DNS results are consistent with the VPN connection and do not clearly expose the local network provider. If DNS results look wrong, review the device network settings, browser DNS-over-HTTPS settings, security software, and any corporate device management profile.
Check WebRTC exposure
WebRTC enables real-time browser features such as calls, screen sharing, and peer-to-peer media. Depending on browser configuration, extensions, and operating system behavior, WebRTC tests can show local or network addresses that users do not expect.
If WebRTC exposure matters for your workflow, test the actual browser you use for calls and account-based services. A privacy-focused browser profile, extension setting, or enterprise policy can change the result, so avoid assuming that two browsers behave the same way.
What these tests do not prove
Leak checks improve confidence in the connection, but they are not legal advice, account-policy advice, or a guarantee that every service will be available. Websites can still use logins, cookies, browser fingerprinting, payment data, device signals, and platform rules.
