IPv6 Leak Test

IPv6 Leak Test - Is Your IP Address Leaking?

A VPN is often used to hide IP addresses, enabling users to surf the web anonymously. However, mistakes when configuring VPN software can lead to sensitive user information, such as their original IP address, being inadvertently leaked. The EXPERTE.com IPv6 Leak Test checks whether your private IPv6 address is leaking, even if you're connected to a VPN.

Note: For the test to produce meaningful results, you must be connected to a VPN.

What Is an IPv6 Leak?

IPv6 is a new Internet protocol that is, in the future, expected to replace IPv4, which is currently in use. However, many computers, networks, and websites are already fully IPv6 capable. Should you now visit a website that is only accessible via IPv6, your computer will use IPv6 to access it. However, if your VPN is only configured for IPv4, your original IPv6 address will be visible.

What Information Is Leaked?

Following an IPv6 leak, the website's admins will be able to see your original IPv6 address. If you use a VPN to surf anonymously, your protection is thereby greatly undermined.

How Does the IPv6 Leak Test Work?

To determine whether you are suffering from an IPv6 leak, the following steps are performed:

  1. We make a request from your browser to a page that is only accessible via IPv6.
  2. If your computer or network supports IPv6, it will access this page via IPv6.
  3. We receive the request and now know your IPv6 address.
  4. We compare the owner of your IPv6 address with the owner of your IPv4 address. If these do not match, there may be a DNS leak.
