How Do I Know If My VPN Is Working Properly?

To ensure your VPN is working properly, we recommend that you run VPN tests in the following directions.

1. Check for IP Leak.

People use VPNs to change IP address for safer browsing. To check if it's working, note your IP address before and after connecting to a VPN. If it hasn't changed, you might have an IP leak.

2. Check for DNS leaks.

Normally, your Internet Service Provider (ISP) can see your online activity through DNS requests. A VPN hides these requests by encrypting them and sending them through its own servers. But if there's a DNS leak, some requests may slip through directly to your ISP's servers, exposing the sites and apps you use. That's why it's important to check for DNS leaks.

3. Check for WebRTC leaks.

WebRTC, commonly integrated into browsers and used by apps such as Google Meet, Skype, and Discord, can sometimes expose your real IP address by bypassing your VPN. To protect your privacy, regularly check for WebRTC leaks to ensure your VPN is effectively concealing your IP and location.

4. Check your VPN status.

Always check that Your VPN is successfully "Connected" to work properly.

5. Test your internet speed.

Using a VPN can slow down your internet since it reroutes your traffic, but a quality VPN will barely affect speed. If a speed test shows a significant drop, there might be an issue.

6. Check for VPN block.

VPNs can get around certain online restrictions, but some services like Netflix may block them. To check if your VPN is working, try accessing a streaming service known for strict VPN blocks.

Running a full VPN test will give you a more complete picture of your VPN in terms of security and functionality. Now keep reading, we will recommend reliable test tools and show you how to do a VPN test step by step.

It's not difficult to accomplish the above tests, you just need the appropriate online tools. Check the list we recommended for you:

How To Test IP Leak?

Checking for IP leaks is easy and takes just a few minutes. Follow the below steps:

⚠️Note: Before you start, disconnect from your VPN. This establishes a baseline to compare your real IP against.

Step 1. Check Regular IP Address

・Use IP address checker to find out your real IP address and note it down.

Step 2. Connect to Your VPN

・Activate your VPN and connect to a server in another location (preferably a different country).

Step 3. Check IP Address Again

・Test IP address again with the tool.

・Your displayed IP address should now be the location of your chosen VPN server. If not, you might have a basic IP leak.

Step 4. Check for IPv6 Leaks

・Run IPv6 leak test tool.

・If it detects an IPv6 address and it matches your real location, you have an IPv6 leak.


・If you find leaks, consult your VPN provider's help resources. They might have specific instructions to fix them.

・Some VPNs have built-in leak protection settings – Turn them on.

Here is an example of an IP leak test result:

As you can see, the IP address and location shown are not those of the VPN server but those of the real device. This means the VPN is leaking the IP address.

How to Fix IP Leak?

・Choose a Trustworthy VPN: Opt for a VPN known for safeguarding privacy and preventing leaks. Services like X-VPN mentions IPv6 leak protection.

・Enable Leak Protection Features

  1. Kill Switch: This feature cuts your internet if the VPN fails, blocking potential IP leaks.
  2. Private DNS: Encrypts DNS requests via the VPN, preventing leaks.
  3. WebRTC Blockers: Stops WebRTC requests to avoid leaks. Some services, like X-VPN, encrypt WebRTC for safe video chats without interruptions.

・Manage IPv6 Traffic: If your VPN lacks IPv6 support, consider disabling IPv6 in your device's network settings.

Adhering to these steps will secure your IP address and maintain online privacy.

How to Text DNS Leak?

Follow these simple steps to check for DNS leaks now:

Step 1. Test DNS Leak without VPN

Navigate to DNS Leak Test tool. Check your IP address and the DNS server location without connecting to a VPN.

Step 2. Test DNS Leak with VPN

Connect your VPN and run the test again.

Step 3. Check the Result

If your VPN is working as it should, then your IP and DNS Server IP should be the same since they both use the VPN server instead of your ISP’s.

Here is an example of a DNS leak test result:

How to Test VPN Speed?

Beyond security, maintaining swift internet speeds is equally crucial for your everyday browsing, streaming, and downloading needs. Let's check another vital metric - VPN speeds.

A VPN speed test checks how fast data travels through your VPN. Factors like your original internet speed, server distance, and protocol choice can impact this. It's important to find a good balance between security and speed.

Follow these quick steps to check your VPN speed:

Step 1. Run Speed Test without VPN

Use online speed test tools like Speedtest. Note the Download and Upload speed results. This is your baseline internet speed without a VPN connection.

Step 2.  Run Speed Test with VPN

Now connect to your preferred VPN server and run another speed test using the same site as before.

Step 3. Compare the Results

Ideally, while using a VPN, you should retain around 80% to 90% of your original internet speeds. Higher speed losses indicate connection issues with that specific VPN server.

・Download Speed: This is the rate at which your device retrieves data from the internet. Higher download speeds enhance website loading, video streaming, and file downloading.

・Upload Speed: This metric shows how quickly your device can send data to the internet. It's vital for video calls, live streaming, and online content sharing, requiring fast upload rates.

・Ping (Latency): Ping measures the response time of your internet connection after sending a request. Lower ping values are preferable for activities needing fast reactions, like online gaming or real-time chats, where delays are detrimental.

How to Improve VPN Speed?

Switch Servers: Choose a server closer to you or less congested for better speed.

Alter VPN Protocols: Switch to faster protocols like WireGuard or IKEv2, but consider the security trade-off.

Wired Connection: Opt for a wired connection to enhance stability and speed.

VPN for Gaming: For gamers, it’s better to use a VPN that can reduce latency with dedicated servers.

How to Test VPN Block?

A VPN helps you access blocked websites, but some sites can detect and block VPN users.

Here are intelligent techniques to bypass VPN blocking:  

  1. Enable obfuscation protocol on your VPN. This disguises VPN traffic as regular HTTPS website data, making it harder for networks to categorize and restrict.
  2. Using a multi-hop VPN, which connects through two or more VPN servers, can increase your anonymity, but it may slow down your internet speed.
  3. Manually override protocol and port settings to mimic ports like TCP 80 and 443 used by normal websites instead of dedicated VPN ports.

We have thoroughly tested the performance of the X-VPN as per the above and got a nice scorecard.
