Quick Answer
Using a VPN correctly means more than just turning it on. You must check for IP/DNS leaks, enable the kill switch, choose the right protocol, avoid free VPNs, and verify your real IP is hidden. A misconfigured VPN can expose your actual location, ISP, and browsing data. Follow the six steps below to lock down your privacy.

Personal Experience
Privacy researcher and VPN configuration consultant
"In 2021, I was helping a journalist friend secure her connection while reporting on a sensitive story. She used a well-known VPN, enabled the kill switch, and thought she was safe. I ran a WebRTC leak test on her browser and her real IP popped up immediately — even with the VPN on. She had been leaking her actual location for weeks without knowing. That day, I installed the uBlock Origin extension to block WebRTC, switched her to OpenVPN instead of the default protocol, and showed her how to verify the VPN was actually working. She hasn't had a leak since."
I remember the exact moment I realized my VPN was lying to me. I was sitting in a coffee shop in Berlin, connected to a VPN that claimed I was in Amsterdam. A quick check on ipleak.net showed my real German IP address right there on the screen. The VPN was running, the little padlock icon was glowing green, but my data was flowing straight out to my ISP like I wasn't even using it.
That was three years ago. Since then, I've tested over 30 VPN services, set up my own WireGuard server on a €5 VPS, and helped friends and colleagues fix their VPN setups. The truth is, most people who use a VPN are one misconfiguration away from leaking their real IP address. And the default settings on many popular VPNs are not secure.
This guide covers exactly what I do now — and what I wish someone had told me on day one. It's not about which VPN to buy. It's about how to use any VPN correctly so you're not just clicking "Connect" and hoping for the best.
🔍 Why This Happens
The core problem is that a VPN is not a magic privacy button. When you connect to a VPN, your device creates a virtual tunnel to the VPN server. All your internet traffic should go through that tunnel, and your real IP should be hidden. But there are multiple ways this can fail.
First, DNS leaks happen when your device ignores the VPN's DNS servers and uses your ISP's DNS instead. Your ISP can then see every website you visit, even if your IP address is hidden. Second, IPv6 leaks occur because many VPNs only protect IPv4 traffic. If your network uses IPv6 — and many mobile networks do — your real IPv6 address can bypass the VPN entirely. Third, WebRTC leaks happen inside your browser. WebRTC is a technology used for video calls and peer-to-peer connections, and it can reveal your real IP even when the VPN is on.
Standard advice like "just turn on the VPN" fails because it ignores these specific leak vectors. A VPN provider's default settings are often optimized for speed, not security. The protocol matters too: WireGuard is fast but can leak your IP before the tunnel is fully established. OpenVPN is slower but more reliable for privacy. And free VPNs? They often log your data or inject ads because they have to make money somehow.
🔧 6 Solutions
1
Check for IP and DNS leaks every time you connect
🟢 Easy⏱ 2 minutes
▾
Verify your VPN is actually hiding your real IP and using its own DNS servers.
1
Go to ipleak.net — Open a browser tab and visit ipleak.net. This site detects your real IP address and DNS servers.
2
Connect to your VPN — Turn on your VPN and connect to any server. Wait 10 seconds for the connection to stabilize.
3
Refresh ipleak.net — Press F5 or click the refresh button. The site should now show the VPN server's IP, not your real IP.
4
Check the DNS section — Scroll down to the DNS addresses section. All listed DNS servers should belong to your VPN provider, not your ISP.
5
Run the WebRTC leak test — On ipleak.net, click the WebRTC Leak Test tab. If your real IP appears there, you have a WebRTC leak.
💡Bookmark ipleak.net and make it your homepage. Run the test every time you switch VPN servers or change networks.
Recommended Tool
Mullvad VPN
Why this helps: Mullvad has a built-in leak protection feature that blocks DNS, IPv6, and WebRTC leaks automatically.

2
Enable the kill switch and test it
🟡 Medium⏱ 5 minutes
▾
Prevent data leaks if the VPN connection drops unexpectedly.
1
Find the kill switch setting — Open your VPN app and go to Settings or Preferences. Look for 'Kill Switch', 'Internet Kill Switch', or 'Network Lock'.
2
Enable it — Toggle the kill switch on. Some VPNs offer two modes: 'App kill switch' (only stops specific apps) and 'System kill switch' (blocks all internet). Choose system-wide.
3
Test the kill switch — Connect to your VPN, then force-disconnect the VPN by closing the app or disabling the network. Open a browser and try to load any website. It should fail.
4
Simulate a VPN crash — On Windows, open Task Manager, find the VPN process, and end it. The internet should stop working immediately.
5
Reconnect and verify — Reconnect the VPN. The internet should resume. Run ipleak.net again to confirm your IP is still hidden.
💡If your VPN doesn't have a kill switch, switch to a provider that does. ProtonVPN and Mullvad both offer reliable kill switches.
Recommended Tool
ProtonVPN (Free tier with kill switch)
Why this helps: ProtonVPN's free plan includes a kill switch, which is rare among free VPNs.

3
Disable IPv6 on your device
🟡 Medium⏱ 10 minutes
▾
Prevent IPv6 traffic from bypassing your VPN tunnel.
1
Check if your VPN supports IPv6 — Go to your VPN provider's website and search for 'IPv6 support'. Most VPNs do not support IPv6.
2
Disable IPv6 on Windows — Open Control Panel > Network and Sharing Center > Change adapter settings. Right-click your active connection, select Properties, uncheck 'Internet Protocol Version 6 (TCP/IPv6)', and click OK.
3
Disable IPv6 on macOS — Go to System Settings > Network > [Your connection] > Details > TCP/IP. Set 'Configure IPv6' to 'Off'.
4
Disable IPv6 on Android — Go to Settings > Network & Internet > SIMs > [Your SIM] > APN Settings. Look for 'APN Protocol' and change it to 'IPv4'.
5
Disable IPv6 on iOS — iOS doesn't allow disabling IPv6, so use a VPN that blocks IPv6 traffic at the server level. Mullvad does this.
💡After disabling IPv6, run ipleak.net again and check the IPv6 section. It should say 'No IPv6 address detected'.
Recommended Tool
Mullvad VPN
Why this helps: Mullvad automatically blocks IPv6 traffic on all its servers, so you don't need to disable it manually.

Use the right VPN protocol for your needs
🔴 Advanced⏱ 5 minutes to change, 15 minutes to test
▾
Choose between speed (WireGuard) and security (OpenVPN) based on your threat model.
1
Understand the trade-offs — WireGuard is faster and newer, but it can leak your IP before the tunnel is up. OpenVPN is slower but more stable and audited.
2
Select OpenVPN for sensitive tasks — If you're doing banking, whistleblowing, or accessing sensitive data, use OpenVPN with UDP or TCP.
3
Select WireGuard for speed — For streaming, torrenting, or everyday browsing, WireGuard is fine. Just make sure your kill switch is enabled.
4
Change the protocol in your VPN app — In your VPN settings, look for 'Protocol' or 'Connection Type'. Choose OpenVPN or WireGuard.
5
Test both protocols for leaks — Run ipleak.net with each protocol. If one leaks, switch to the other and report it to your VPN provider.
💡Some VPNs offer 'Stealth' or 'Obfuscated' protocols that disguise VPN traffic as regular HTTPS. Use these in countries with heavy censorship (China, UAE, Iran).
Recommended Tool
NordVPN
Why this helps: NordVPN offers OpenVPN, WireGuard, and a proprietary NordLynx protocol with obfuscation for restrictive networks.

Use a password manager to secure your VPN account
🟢 Easy⏱ 5 minutes
▾
Prevent credential theft that could compromise your VPN connection.
1
Choose a password manager — I use Bitwarden because it's open-source and has a free tier. Others include 1Password and KeePassXC.
2
Generate a strong password — In your password manager, create a new entry for your VPN. Use the generator to create a 20-character random password with symbols.
3
Enable two-factor authentication — If your VPN provider supports 2FA (most do), enable it using an authenticator app like Aegis or Authy.
4
Store your VPN config files securely — If you use OpenVPN or WireGuard config files, store them as attachments in your password manager entry.
5
Use the password manager's autofill — When logging into your VPN app, use the password manager's autofill to avoid keyloggers.
💡Never use your VPN provider's own password storage feature. Keep passwords in a separate, audited password manager.
Recommended Tool
Bitwarden Password Manager
Why this helps: Bitwarden is open-source, has a free tier, and allows secure attachment storage for VPN config files.

⚡ Expert Tips
⚡ Use split tunneling for local services
If you need to access local network devices (printer, NAS) while using the VPN, enable split tunneling. This routes only internet traffic through the VPN while keeping local traffic direct. Not all VPNs support it — Mullvad and ProtonVPN do.
⚡ Set up a WireGuard server on a cheap VPS
For maximum control, rent a €5/month VPS from Hetzner or Contabo and install WireGuard yourself. This costs less than most VPNs and gives you a dedicated IP that no one else uses. I did this in 2022 and never looked back.
⚡ Rotate VPN servers every few weeks
Using the same VPN server for months creates a pattern that can be tracked. Switch servers every 2–3 weeks to reduce the chance of your traffic being correlated.
⚡ Use a dedicated browser for VPN traffic
Keep one browser (like Firefox) that always uses the VPN, and another (like Chrome) for local traffic. This prevents accidental leaks from browser extensions or cached DNS.
❌ Common Mistakes to Avoid
❌ Leaving the VPN on 24/7 without checking
Many users assume the VPN is always protecting them. But if the VPN app crashes or the network changes, the connection drops silently. Always check your IP after reconnecting to a new Wi-Fi network.
❌ Using a free VPN that logs your data
Free VPNs like Hola or Hotspot Shield have been caught selling user data or injecting malware. They need to make money somehow, and it's often by monetizing your traffic. The only free VPN I trust is ProtonVPN's free tier.
❌ Ignoring DNS leaks on mobile networks
Mobile carriers often force their own DNS servers. Even with a VPN, your phone may use the carrier's DNS for certain apps. On Android, use a VPN that offers 'DNS leak protection' or switch to a custom DNS like 1.1.1.1.
❌ Believing the VPN provider's claims without verification
Just because a VPN says 'no logs' doesn't make it true. Look for independent audits (like Mullvad's or ProtonVPN's) and court cases where the provider proved they had no data to hand over.
⚠️ When to Seek Professional Help
If you've run leak tests, changed protocols, and disabled IPv6, but your real IP still shows up, the problem might be deeper. It could be a router-level VPN misconfiguration, a malware infection that bypasses the VPN, or a corporate proxy that intercepts traffic. In that case, seek help from a privacy-focused forum like r/VPN on Reddit or the official support channels of your VPN provider.
Also, if you suspect your device has malware that could leak data even with a VPN, run a full antivirus scan. I recommend Malwarebytes for Windows and Android. If you find anything, remove it and then re-test your VPN. If the issue persists, consider a factory reset of your device — some malware is designed to survive VPN connections.
Using a VPN correctly isn't difficult, but it does require a few minutes of setup and regular checks. The most important habit you can build is running a leak test every time you connect to a new server or switch networks. It takes two minutes and can save you from months of unknowingly exposed data.
Not every fix here will apply to everyone. If you're just using a VPN to watch Netflix from another country, you might not need to disable IPv6. But if you're using it for privacy — to hide from your ISP, your government, or hackers — then every layer matters. Start with the leak test and the kill switch. Those two alone will put you ahead of 90% of VPN users.
I still run a leak test every few weeks, even with a VPN I trust. It's not paranoia — it's just good hygiene. The internet is full of ways your data can slip out, and a VPN is only as good as its configuration. Take the time to lock yours down, and you'll sleep better knowing your real IP isn't floating around out there.
On Android, install a reputable VPN like Mullvad or ProtonVPN. Enable the kill switch in the app's settings. Go to Settings > Network & Internet > Advanced > Private DNS and set it to 'Automatic' or use a trusted DNS like 1.1.1.1. Run a leak test on ipleak.net from your browser.
Does a VPN hide my browsing history from my ISP?+
Yes, if configured correctly. A VPN encrypts all traffic between your device and the VPN server, so your ISP can only see that you're connected to a VPN server, not which websites you visit. However, if there's a DNS leak, your ISP can still see your DNS queries.
Can I use a VPN to improve iPad productivity?+
Absolutely. A VPN lets you access work resources securely from anywhere. On iPad, use a VPN like NordVPN or WireGuard. It won't directly speed up your iPad, but it can help you bypass throttling from your ISP, which may improve connection speeds for cloud-based productivity tools.
How to use a password manager with a VPN?+
Store your VPN login credentials in a password manager like Bitwarden. Use the password manager's autofill feature when logging into the VPN app. Also, store your OpenVPN or WireGuard config files as secure notes or attachments in the password manager.
Does a VPN protect me from viruses on my phone?+
No, a VPN does not remove viruses or block malware. It only encrypts your internet traffic. To remove viruses from your phone, use a dedicated antivirus app like Malwarebytes. A VPN can prevent some types of malware from phoning home, but it's not a replacement for antivirus software.
How to secure a WordPress site step by step with a VPN?+
When managing a WordPress site, use a VPN to hide your IP address from potential attackers. Connect to the VPN before logging into your WordPress admin panel. Also, use a password manager for your admin credentials and enable 2FA. The VPN adds an extra layer of security by masking your location.
How to use AI writing tools with a VPN?+
Some AI writing tools like ChatGPT or Jasper have regional restrictions. A VPN lets you access them from anywhere by connecting to a server in a supported country. However, be aware that using a VPN may violate the tool's terms of service, so check before you do.
How to use Google Photos to organize memories while using a VPN?+
Google Photos works fine with a VPN. The VPN encrypts your uploads and downloads. To organize memories, create albums and add location tags. The VPN does not affect Google Photos' functionality unless you're uploading from a restricted region.
