Different Types of Leaks
A DNS leak is perhaps the most common form of leak you may encounter while using a VPN extension.
It occurs when your DNS requests are routed outside of the encrypted VPN tunnel, meaning your ISP is able to see all of the websites you visit. The specific content remains hidden, but your browsing data will still be exposed.
IPv6 leaks are becoming increasingly common with VPN extensions during the transition from IPv4 to IPv6.
These types of leaks expose your true location, allowing you to be tracked and monitored by third parties, including your ISP. Worryingly, they can also be linked to your online activity.
WebRTC leaks are caused exclusively by a feature in your browser that allows it to form real-time communications with the websites you visit.
When these special communications channels bypass the VPN tunnel, your true IP address is exposed, meaning your ISP or government can snoop on or log your online activity.
