Newsoftwares.net provides this technical resource to help you verify the integrity of your virtual private network connections across various desktop and mobile platforms. This material focuses on the practical steps required to ensure that your data remains truly encrypted and that no sensitive identifiers are escaping the secure tunnel. By following these professional verification patterns, users can identify silent failure modes that standard IP checks often overlook. This overview is designed to simplify complex network diagnostics into a repeatable workflow, allowing anyone to confirm their digital privacy is intact while working on public or untrusted networks.
Direct Answer
To verify if a VPN is really encrypted and working correctly, you must perform a multi-layered check that includes a public IP audit, a DNS leak test, and a packet capture analysis. Simply seeing a change in your public IP is insufficient proof of security; you must ensure that your DNS requests remain inside the tunnel and that your browser is not leaking your real location through WebRTC or IPv6 vulnerabilities. Using a tool like Wireshark to confirm that all outgoing traffic appears as encrypted UDP or TCP packets directed only to the VPN server provides the ultimate technical confirmation. Additionally, always use modern protocols like WireGuard or OpenVPN with AES-256-GCM ciphers and ensure the kill switch feature is active to prevent data exposure during intermittent connection drops.
Gap Statement
Most is my VPN working writeups stop at my IP changed, then call it done. That misses the real failure modes. What is missing includes DNS and IPv6 leaks, plus browser WebRTC leaks that expose your local identity. Furthermore, browser-level DNS over HTTPS can often bypass your VPN DNS settings entirely. Many resources also fail to provide a simple packet capture check that proves your traffic is inside an encrypted tunnel. Treating an IP change as sole proof of encryption is a dangerous technical error that leaves users vulnerable to sophisticated tracking and data interception.
In about 10 minutes, you will know whether your VPN tunnel is actually encrypted, leak free, and behaving the way you think it is by following a structured diagnostic path.
1. Defining Encryption In VPN Environments
A VPN creates a secure tunnel between your device and a remote VPN server. Traffic inside this tunnel is encrypted on the wire between those two specific points. Once the traffic exits the VPN server to reach the open internet, it relies on the encryption supported by the destination website, which is typically HTTPS. It is vital to remember that while you can verify tunnel encryption from your own device, you cannot prove what the VPN provider logs internally just by testing the encryption state.
1.1. Protocol And Cipher Selection
Protocol choice is the foundation of your security. WireGuard is built around a modern, fixed cryptographic set including Curve25519 and ChaCha20, offering high speed and robust security. OpenVPN is highly configurable and should be set to modern data channel ciphers like AES-256-GCM or ChaCha20-Poly1305. If you encounter older protocols like PPTP or L2TP in a corporate environment, consider them a red flag as Microsoft has announced their deprecation in favor of more secure options like SSTP and IKEv2.
2. Prerequisites And Testing Safety
Before beginning your verification, use a network you control or at least one you trust. Pause any sensitive activities, such as online banking or medical portal access, for the duration of the test. Ensure your VPN client is updated to the latest version and turn off any other tunneling tools, such as proxies or custom DNS applications, to avoid conflicting results.
2.1. Evidence Collection List
- Proof: One screenshot of your IP address both before and after the VPN connection.
- Proof: One screenshot of comprehensive DNS leak test results.
- Proof: One screenshot confirming the connected state and protocol within your VPN app.
- Proof: A Wireshark capture showing encrypted flows exclusively to the VPN server.
3. Step 1: Tunnel Status Confirmation
Open your VPN application and initiate a connection. Look for the connected badge, but remain cautious; a connection indicator can sometimes appear even if the tunnel is in a drop and reconnect loop. Monitor the app for 30 seconds to ensure the state is stable.
- Action: Confirm the protocol is set to WireGuard, OpenVPN, or IKEv2.
- Verify: Ensure the server location matches your intended exit region.
- Verify: Check that a connection timer is counting up consistently without resetting.
4. Step 2: Public IP Reality Check
With the VPN disconnected, visit a public IP test site and record your real location and address. Then, connect the VPN and refresh the page. This is the fastest way to confirm basic routing is functioning as expected.
- Action: Use a private browsing window to prevent cached results from showing your old IP.
- Gotcha: If your IP flips back and forth between your real location and the VPN server, your connection is unstable.
5. Step 3: DNS Leak Testing
DNS is the system that maps website names to IP addresses. A DNS leak occurs when these requests bypass your encrypted VPN tunnel and go directly to your ISP. This allows your ISP to see every website you visit, even if the content of those visits is encrypted.
- Action: Run a DNS leak test while the VPN is active and review the resolver list.
- Gotcha: Browser features like DNS over HTTPS can bypass the VPN path. Set this to off or use system in your browser settings if you see unexpected resolvers.
- Verify: The reported DNS servers should belong to your VPN provider and match the VPN exit country.
6. Step 4: WebRTC Leak Analysis
WebRTC is a browser-based technology for real-time communication that can inadvertently expose your local network IP and even your real public IP in certain configurations. Passing an IP and DNS test does not guarantee you are safe from WebRTC fingerprinting.
- Action: Run a WebRTC specific leak test and check the detected IP section.
- Verify: Only the VPN IP should appear in the results.
- Fix: If your real IP is visible, use a reputable browser extension or tighten the privacy flags in your browser configuration to block WebRTC IP exposure.
7. Step 5: IPv6 Leak Protection
Some VPN providers only tunnel IPv4 traffic, leaving IPv6 requests to go through your ISP. This can leak your true location and identity even if your IPv4 settings look perfect. If your VPN app has an IPv6 toggle, ensure it is set to either tunnel or block IPv6 traffic entirely.
- Verify: Rerun your IP test and confirm that either no IPv6 address is detected or the detected IPv6 address matches the VPN server region.
8. Step 6: Technical Proof via Packet Capture
This is the strongest method to prove your tunnel is encrypted without needing access to the VPN server logs. By using Wireshark, you can observe the raw data leaving your network interface.
- Action: Install Wireshark and start a capture on your active network interface (Wi-Fi or Ethernet).
- Action: Connect your VPN and browse several normal websites.
- Action: Stop the capture and filter for the VPN server IP address.
- Verify: You should see a single dominant flow of encrypted UDP or TCP packets. You should not see any readable HTTP traffic or DNS queries to external resolvers.
9. Step 7: Kill Switch Verification
A kill switch is a critical safety feature that blocks all internet traffic if the VPN connection drops. This prevents your device from defaulting to your ISP connection and leaking data during a tunnel failure.
- Action: Enable the kill switch in your VPN settings and initiate a stable connection.
- Action: Force a connection drop by briefly disabling your Wi-Fi or switching to a different network.
- Verify: Try to load a web page or run a ping command; it must fail immediately. Once the VPN reconnects, traffic should resume through the secure tunnel.

12. Common Failure Modes And Fixes
If your verification steps fail, follow this diagnostic hierarchy before assuming the VPN provider is at fault. Most issues originate from local configuration errors or OS-level overrides.
- Symptom: IP address remains unchanged. Action: Force a connection refresh and check for split-tunneling rules that might be excluding your browser.
- Symptom: DNS test shows your ISP. Action: Check browser settings for secure DNS or DNS over HTTPS and disable them to allow the VPN tunnel to take control.
- Symptom: VPN connects but no traffic moves. Action: Switch protocols from UDP to TCP or try a different port (e.g., 443 or 1194) to bypass network blocks.
- Symptom: IPv6 leak detected. Action: Disable IPv6 in your device network adapter settings if your VPN client does not support blocking it.
13. Complementary Tools From Newsoftwares
A VPN protects your data in motion, but it does not protect the data stored on your device. For comprehensive security, you should pair your VPN verification habits with robust encryption for your local files and cloud accounts.
13.1. Folder Lock For Data At Rest
Folder Lock uses AES-256 bit encryption to secure files, folders, and drives on your computer. While the VPN hides your traffic from the coffee shop Wi-Fi admin, Folder Lock ensures that even if your laptop is physically stolen, your documents remain impenetrable. This is a vital layer for any mobile professional.
13.2. Cloud Secure For Account Protection
Cloud Secure allows you to add a password gate to your cloud storage folders, such as Google Drive and OneDrive, on your Windows PC. This ensures that even if you are logged in and using a VPN, a bystander cannot casually browse your synced files if you step away from your workstation.
13.3. History Clean For Diagnostic Privacy
Testing a VPN involves visiting many diagnostic sites and checking network logs. History Clean helps you remove these local footprints from your computer once your verification is complete, ensuring your testing process does not leave behind a breadcrumb trail of your security habits.
Frequently Asked Questions
Does a VPN encrypt everything on my phone?
A VPN typically encrypts all traffic routed through its virtual interface. However, apps configured for split-tunneling or those using direct local network paths may bypass the encryption entirely. Always check your VPN app settings for application exclusions.
Can my ISP still see what sites I visit with a VPN?
If your DNS is leaking, your ISP can see every domain name you query. If your DNS is properly contained within the tunnel, the ISP only sees that you are connected to a specific VPN server IP address, without knowing your final destination.
Why does my location still show as my real country even with a VPN?
Modern devices use more than just your IP to determine location. GPS data, local Wi-Fi network scanning, and browser cookies can all reveal your real position. You must disable location permissions and clear cookies to achieve true geographical masking.
What is the quickest way to spot a broken VPN?
The fastest red flag is when your public IP address remains the same after connecting. Another immediate check is running a DNS test; if your ISP’s name appears in the results, your VPN tunnel is effectively bypassed for name resolution.
Is WireGuard more secure than OpenVPN?
WireGuard is generally considered more modern and efficient due to its smaller code base and fixed cryptographic primitives. OpenVPN remains equally secure if it is configured correctly with modern AES-GCM ciphers, though it is more prone to configuration errors.
Why does my DNS leak test show a resolver I do not recognize?
This is often caused by browser-level DNS over HTTPS settings. Browsers like Firefox or Chrome may use their own encrypted DNS providers (like Cloudflare or Google) which bypasses the VPN tunnel DNS. Ensure your browser is set to use the system default DNS.
What should I do if only some apps use the VPN?
This indicates that split-tunneling is active. Navigate to your VPN application settings and ensure that either all traffic is routed through the tunnel or that your specific browsers and apps are included in the protection list.
How can I test a kill switch without risking my accounts?
Open a command prompt and start a continuous ping to a public address (e.g., ping 8.8.8.8 -t). Disconnect your network or kill the VPN process; the ping must stop immediately. Do not conduct this test while logged into sensitive sessions.
Why does a WebRTC leak only happen in one browser?
WebRTC implementation varies by browser engine. Firefox has different privacy controls compared to Chromium-based browsers like Chrome or Edge. You must verify and secure each browser you use individually.
If my VPN is encrypted, can the VPN provider read my traffic?
The provider sees your traffic before it exits their server. If the destination site uses HTTPS, they only see the domain name, not the page contents. For unencrypted HTTP traffic, they can see the full content of your communication.
My VPN works on mobile data but fails on office Wi-Fi, why?
Many corporate networks block known VPN ports and protocols (like UDP 51820 or UDP 1194). You may need to switch to TCP port 443 or use an obfuscated protocol that makes your traffic look like standard HTTPS web browsing.
What should I save as proof for compliance?
Maintain a folder of dated screenshots showing your connection protocol, successful DNS and WebRTC test results, and an IP change confirmation. For high-security requirements, include a small packet capture file demonstrating the encrypted tunnel flow.
Conclusion
Verifying your VPN connection is a vital security habit that ensures your technical defenses match your privacy expectations. By looking beyond a simple IP change and auditing DNS, WebRTC, and raw packet data, you can catch silent leaks before they expose your identity. Integrating modern protocols like WireGuard and enforcing strict kill switch policies creates a resilient shield for your data in motion. For total data sovereignty, always pair your verified VPN with local encryption tools like Folder Lock to protect your data at rest. Continuous verification is the only way to maintain a truly secure and private digital footprint in a world of complex network threats.
