Virtual Provider Networks (Virtual Provider Networks – VPNs) are used for various purposes. They usually include protecting privacy on the Internet, improving connection security on the Internet, bypassing censorship and any kind of restriction, or purely for professional purposes.
If you use a VPN regardless of the purpose you need it for, you may want to be sure that your real IP address can leak.
The reason for this is simple: Your IP address is directly linked to you. So a court order against your VPN provider is enough to reveal very private information, such as the country and region you are connected to.
Let's see if your VPN leaks your IP address
The way we will see below is recommended unconditionally for every time you connect to a virtual network, so that you can ensure that your connection does not leak information about your real IP address. And to avoid doing it constantly, perform the test at least the first time you connect and then you can repeat it occasionally.
There are many websites you can use for this purpose, and the good news is that all you need to do is open the website to find out if your VPN is leaking information it shouldn't.
We will mention three different websites for checking IP leaks.
Note: It is recommended to disable any script blockers you use to perform your tests, as they may block scripts that control DNS.
Let's look at the 3 sites:
and
If you see different IP addresses or locations, they report the IPv4 IP address, and the IPv6 IP address. Then there is a possibility that third‑party websites or other services can see both IP addresses.
In the tests we used the “VPN” of Opera (we would rather call it a proxy) and the anonymous Tor network on a Linux system.
We observed that anonymity in the Opera browser was not that absolute since the website ipleak.net, although it immediately displayed a different IPv4 IP from that of my actual connection, continued to search (appears as a black line under the “No forwarded IP detected….”
On the same page, using the anonymous Tor network, we had absolute results as you will see in the image below.
The second leak detection service dnsleaktest.com does not have as specialized tools as the first, or if it does they are not shown in the results. In other words, it does not appear to check for leaks via WebRTC, if the proxy is secure, etc.
Even though this service has a button that says “Extended Test” it does not display the results of the first one.

As for the third page, although it seems to be searching it does not display any results at all, or at least it did not appear in the system where we performed the tests:
