Ipv6 dns leak test
If for any reason a website can see your real IP address when using a VPN then you have an IP leak. Our IP leak tool tests for all known types of IP leak.
VPN Leak Testing Tool
When using a VPN service it should be impossible for any website you visit to identify you by your real unique internet address (IP address). All a website (or any other internet resource) should be able to see is the IP address of the VPN server you are connected to.
If for any reason a website can see your real IP address when using a VPN then you have an IP leak. Our IP leak tool tests for all known types of IP leak.
What is IPv4?
Every internet connection is assigned a numerical IP address that computers use to uniquely identify it. The IPv4 system has been used for this since the early days of the internet, and IPv4 addresses remain by far the most common type of internet address.
One day, IPv6 addresses (see below) will completely replace IPv4 addresses, but until the new standard is much better supported, even connections with an IPv6 address are also assigned an IPv4 address for compatibility reasons.
What is an IPv4 leak?
This means a website can see your real IPv4 address, and isn’t really a “leak” as such. It means your VPN is not enabled or is not simply not working at all.
What is IPv6?
IPv4 addresses are running out. Fast. The new IPv6 standard fixes the issue by using addresses much longer, thereby providing an awful lot more of them (around 340 billion billion billion billion!).
Unfortunately, although essential to the future growth of the internet, adoption of IPv6 at all levels has been slow. The result is most internet services and Operating Systems now operate a dual-stack approach, where (when IPv6 connectivity is available at all) internet traffic is sent over both an IPv4 interface and an IPv6 interface.
What is an IPv6 leak?
An IPv6 leak occurs when your IPv4 connection is correctly routed through the VPN interface, but your IPv6 connection is routed via your ISP as normal.
This means that websites can’t see your real IPv4 address, but they can see your real IPv6 address. IPv6 leaks can only occur if your device has IPv6 connectivity.
Our test ensures IPv6 connections are either being routed through the VPN interface, or that IPv6 connections are blocked in order to prevent connections outside the VPN interface.
What is a WebRTC leak?
WebRTC is an HTM5-based platform that allows high quality voice and video communication inside all modern browser windows.
In order to achieve seamless browser-to-browser communication through obstacles such as firewalls, WebRTC broadcasts your real IP address(es) to STUN servers, which keep a list of both users’ public IP addresses and their real IP addresses.
This has the unfortunate side-effect of allowing websites to bypass your VPN and find out your real IP address(es) by simply making a WebRTC STUN request.
Although primarily a browser issue, many VPN services can heavily mitigate against (but entirely fix) this problem. Our test checks for both IPv4 and IPv6 WebRTC leaks.
What is a DNS address?
The Dynamic Name System (DNS) is used to translate the easy-to-understand and remember web addresses that we are familiar with (URLs), to their “true” numerical IP addresses.
Your DNS address is the IP address of the DNS server which performs this translation, which in the normal course of things belongs to your ISP.
It is not unique to you, but your ISP can use your DNS queries to track which websites you visit, and websites you visit can contact your ISP to find out which of their users visited their website at a specified time.
What is a DNS leak?
When using a VPN, DNS queries should be sent through the VPN interface to be handled by the VPN provider – instead of your ISP. Most VPN services run their own DNS servers, but some proxy the queries to third party providers. This is fine, since the third party DNS provider doesn’t know who made the request.
A DNS leak occurs when a DNS query is sent outside the VPN interface, and is therefore handled by your ISP instead of the VPN provider. This can happen for a number of reasons, but a good VPN client should prevent it.
Our test checks for both IPv4 and IPv6 DNS leaks.
Help! I have an IP leak! What should I do now?
If our test detects that you have an IP leak, don’t panic! Please consult our Complete Guide to IP Leak Protection for a solution (the simplest always being to just switch to a VPN that doesn’t leak!).

You are connecting from an IPv4 address:
We will check if you can also connect through an IPv6 address.
How Can I Prevent IPv6 Leaks?
Most VPNs operate on IPv4. If you were to connect to a website that runs on IPv6, your data would exit the secure VPN tunnel and be exposed. By connecting to the internet with PIA VPN, you get IPv6 leak protection. PIA VPN will disable IPv6 traffic to ensure that no IPv6 internet data leaks out from your regular internet connection while connected to the VPN.
Benefits Of Hiding Your IP Address
PIA VPN acts like a safety buffer between your device and the websites or applications you connect to.
An extra layer of protection
Cannot be tracked
Internet traffic is encrypted
Choose server location
IP address is concealed
Access your favorite content
Why Choose PIA VPN?
Anonymity
Strict no-logs policy so you’re totally anonymous all the time.
Transparency
Trusted open-source VPN protocols for full transparency.
Expertise
10+ years of expertise as the world’s leading VPN provider.

What Is IPv6?
An IP address is a unique identifying number assigned to an internet-capable device. Most devices have an IP address assigned using the IPv4 protocol. But as the supply of available IPv4 addresses dwindles, IPv6 was developed to allow for more addresses to be created — trillions of trillions of addresses — to meet the growing demand of internet-capable devices. Many devices support IPv6 addresses, but most websites currently do not, as the technology is relatively new and the cost of upgrading and adoption is high.

IPv6 Leak Test
IPv6 is the latest iteration of the internet protocol (IP), but it is yet to be implemented across the globe. Due to the many shortfalls presented by IPv4, and since a new standard was required, IPv6 was introduced to the world. Unlike IPv4, IPv6 can support a greater number of devices and servers, meaning an even broader internet.
Also, the format of IPv6 is completely different from IPv4. Unlike the IPv4 where you had three digits followed by a dot repeated until a quad-digit is formed, something like this: 255.255.255.255. IPv6, on the other hand, consists of eight numbered strings, each containing four characters (alphanumeric), separated by a colon, supports 128-bit addresses and provides approximately 340, 282, 366, 920, 938, 463, 463, 374, 607, 431, 768, 211, 456 IP addresses for us to use.
How IPv6 Leaks Occur?
While some ISPs and servers support IPv6, majority of websites still only support IPv4. This leads to issues like your IPv6 leaking. For instance, if your ISP supports IPv6, then you will get both IPv4 and IPv6 from your ISP. Let’s assume that you want to visit Google and it only supports IPv4. In this case, the request sent by your device to Google’s server will contain both your IPv4 and IPv6 address.
The same scenario will apply even if you are using a VPN. To prevent this from happening, your VPN must support IPv6 leakages and immediately block all IPv6 traffic to keep your real identity hidden and secured from the outside world.
PureVPN IPv6 Feature
IPv6 leakage can become a menace – it can reveal your identity and you won’t even figure it out. The extra effort to secure yourself before your personal information is tracked or recorded by an unauthorized individual or team never goes to waste; it always pays off.
To ensure that you keep on receiving complete online anonymity, PureVPN offers IPv6 Leak Protection which is built to safeguard your online traffic from the eyes of hackers, trackers, and any other spying entity. Most VPNs suffer from IPv6 leak issues that expose the actual online identity of the person using the VPN. PureVPN ensures that you real identity remains hidden at all times by:
- Blocking IPv6 traffic on your device
- Keeping your activities anonymous
- Keeping zero logs of your web activities.
