Network Setting Changes
Manual configuration, operating system updates, or network changes can cause a device to use DNS servers outside the protected VPN connection
Incorrect VPN Routing
Some VPN setups may allow DNS requests to travel outside the encrypted tunnel, exposing website lookups through the user’s normal internet provider
Third-Party Apps
Certain apps, browser extensions, security tools, or network utilities may alter DNS behavior or send requests outside the intended path
Malicious DNS Changes
Malware or unauthorized software can change DNS settings and redirect website lookups through unsafe or untrusted resolvers
ISP DNS Redirection
Some internet providers may redirect DNS requests through their own systems, which can expose browsing patterns or override the user’s preferred DNS settings
