Learn why browser and DNS behavior matters when reviewing a protected connection.

DNS requests

DNS translates domain names into network addresses. Resolver choices may expose browsing-related lookup information.

WebRTC behavior

Real-time browser features can reveal additional network addresses in some configurations.

Test carefully

A test result is diagnostic, not a guarantee of anonymity. Review browser settings and the scope of the VPN product you use.

Practical reminder

A VPN is one privacy tool, not a substitute for account security, software updates, or careful online decisions.
