VPNs can be a powerful privacy tool. It hides your IP address as well as your location. However, not all VPNs protect your privacy as well as they should.

Misconfigured apps can expose your real IP address and reveal your true identity. If you’re concerned about your connection status, you should do a VPN test. How can you check if VPN is leaking your IP address?

Let’s first take a look at the ways how your service can leak your IP address.

What is IP Leak and How Can It Happen?

VPN leaks can reveal your real IP address when you are connected to a server. This can be caused by misconfigurations or poor technical implementation. Your identity can be exposed by a VPN leak. It could leak your IPv4, IPv6, and DNS. Your IP will never be leaked by a secure service.

An IP address is the best way to identify who you are online. This information should be hidden by VPN services. Your IP could be leaked, which can lead to:

  • All online activity can linked to you
  • Your connection is now public
  • It is possible to detect torrenting and P2P files
  • Websites can identify you
  • Your ISP can see where you browse

Let’s see what leaks a VPN may have.

IPv4 & IPv6 Leaks

IPv4 is most commonly used version of an IP address on the internet. It acts as a direct link between your browsing activities and your IPv4. It is unacceptable for a VPN to have an IPv4 leak. If it does, it is likely that there are serious technical issues. This VPN service should be stopped and you should switch to one that doesn’t leak.

IPv6 leak looks like an IPv4, but is just another version of the same address. Both versions of the address are already assigned by many ISPs, such as Comcast or Verizon.

If a VPN provider does not take into account IPv6 there’s a chance it can leak it. The best VPN providers offer IPv6 leak protection to block this type of IP.

DNS Leak

DNS leaks could reveal which websites you’re visiting to your ISP. Before you can connect to the website, your device asks for the IP address. These DNS requests should be sent through an encrypted VPN tunnel.

If VPN apps do not handle these requests there’s a risk that the websites you access are exposed. It is recommended that VPNs use their own private DNS addresses to prevent this.

WebRTC Leak

WebRTC is a common browser feature that allows for real-time communication. This technology allows for quicker file transfer speeds, live streaming and video chats. Privacy is not the best option.

WebRTC is able to create communication channels that are not encrypted. VPN apps cannot control this feature so it must be done manually. A VPN extension can be used to disable this feature.
