As someone who’s always online, I’ve grown to appreciate VPNs for keeping my digital footprints under wraps. Top-notch VPNs are great at this, packing features like data encryption and IP masking. They’re basically like your internet bodyguard.
But, let’s be real, even the best bodyguards have off days. Sometimes, VPNs might slip up and not fully hide your IP address. That’s when your personal details could spill out all over the web.
One such slip-up is the IPv6 leak. This post digs into what IPv6 is, why leaks happen, and tips on spotting and stopping IPv6 leaks.
What’s IPv6 Anyway?
Picture this: Every gadget you’ve got holds two IP addresses – one for your home network chats (the private IP) and one for the big wide web (the public IP). Your home network devices use private IPs like 192.168.X.X to talk amongst themselves.
Your public IP, handed to you by your ISP, is your ticket to the online world. When you hop onto a VPN, it swaps your ISP-given IP with one from its own stash.
Here’s where IPv4 and IPv6 come into play. IPv4 is the old-school type, like the private IPs I mentioned. IPv6, with its longer, more complex format (like 2020:0de6:0001:0084:0100:9c4e:0390:7244), is the new kid on the block, designed to keep up with the ever-growing number of devices.
Despite the shift to IPv6, it’s still a work in progress. Many websites and ISPs juggle both IPv4 and IPv6. And most of our devices are already IPv6-ready.
Decoding IPv6 Leaks
Ever wonder why sometimes your online cover is blown even when using a VPN? This might be due to an IPv6 leak. Let me break it down for you.
Many websites are still on the IPv4 bandwagon, and plenty of VPNs are too. So, if you visit an IPv6 site with a VPN that’s not up to speed with IPv6, there goes your IP address, waving hello to the world.
An IPv6 leak is like a chink in your digital armor, revealing your identity without you even realizing it.
Spotting an IPv6 Leak
Here’s the deal: If your ISP is all about both IPv4 and IPv6, but you hit up an IPv4-only site, your device might give away both your IP addresses. This is where you could get an IPv6 leak, even with your VPN on.
Figuring out if you’re on a site using IPv4 or IPv6 or if you’re leaking data might sound like hacker-level knowledge, but trust me, checking for leaks is surprisingly simple. Here’s a quick guide:
-
First, pop over to a site like whatismyipaddress.com or just Google "what is my IP?" You’ll see your current IP details, like your address and where you seem to be in the world.
-
Next, close your browser, fire up your VPN, and connect to whatever location floats your boat.
-
Lastly, head back to an IP leak testing site (like browserleaks.com or ipleak.net). Now, your IP details should look different. If they’re the same, you’ve got a leak on your hands.
Preventing IP Leaks Effectively
So, you’re wondering how to stop your IP address from playing hide and seek without your permission? Well, I’ve got some tips that might just do the trick.
1. Choose a VPN With IPv6 Leak Shield
Even though IPv6 leaks can happen through a VPN, the right VPN is actually your best bet. Look for one that’s got IPv6 leak protection. The crème de la crème of VPNs either handle IPv6 traffic like a pro or block it outright.
When picking a VPN, make sure it’s one that either fully supports IPv6 or says a firm no to it. I’ll give you a rundown of some top VPN picks with solid IPv6 leak protection later on.
2. Turn Off IPv6 on Your Device Yourself
With the internet still playing catch-up with IPv6, a no-brainer solution to avoid leaks is to disable IPv6 on your gadgets. Here’s how you can do that, at least on a Windows machine:
DIY Guide to Disabling IPv6 on Windows
-
Head over to the Control Panel (a quick search from the Start menu should get you there).
-
Click on ‘Network and Sharing’ or ‘View Network Status and Tasks’ if you’re in category view.
-
Find ‘Change adapter settings.’
-
Right-click on your internet connection, then hit ‘properties.’
-
Look for ‘Internet Protocol Version 6 (TCP/IPv6)’ in the list and uncheck it.
-
Click OK, and voila! You’ve just told IPv6 to take a break on your system.
Disabling IPv6 on macOS
Here’s a quick guide for the macOS users:
-
Jump into System Preferences.
-
Hit Network.
-
Choose your internet connection, then go for Advanced.
-
Under the TCP/IP tab, you’ll see a dropdown next to ‘Configure IPv6’. Set it to ‘off’.
Turning Off IPv6 on Linux
Linux users, you’ve got two ways to do this – the command line or the network manager. The network manager is easier, so let’s go with that:
-
Head to Settings and select Network.
-
Click on the settings/options tab for your connection.
-
In the IPv6 tab, under ‘IPv6 Method’, choose Disable.
-
Hit Apply, and you’re good to go.
IPv6 Leak Protection in VPNs
Despite IPv6 not being as widespread as IPv4, it’s still vulnerable to the same leaks. That’s why IPv6 leak protection in VPNs is such a big deal. This feature either makes sure your IPv6 traffic is safely tunnelled through the VPN or blocks it completely, keeping your online identity under wraps even when visiting IPv6 sites.
Choosing a VPN with IPv6 Leak Protection
Finding a VPN that ticks all the boxes, including IPv6 leak protection, can be a bit of a hunt. But I’ve got a solid recommendation for you.
NordVPN
NordVPN isn’t just another name in the VPN world; it’s a heavyweight. Its IPv6 Leak Protection is like a digital bodyguard for your IPv6 interface, ensuring only IPv4 traffic goes through NordVPN’s encryption and rerouting process. The best part? It’s all automatic – no manual setup needed.

Wrapping Up
IPv6 is the future of IP addresses, but it’s still in the minority. We rely on VPNs for online safety, but an IPv6 leak can throw a wrench in the works. This guide has walked you through leak detection, prevention methods, and a VPN recommendation for complete IPv6 leak protection.
