A VPN is designed to protect your privacy by encrypting your internet traffic and hiding your IP address. However, even with a VPN enabled, there is a risk of something called a DNS leak, which can expose your browsing activity.
A DNS leak is one of the most common privacy issues VPN users face, especially in restricted regions where network filtering is more aggressive. If you need a VPN that still works reliably in such conditions, check this guide: Best VPN for Russia 2026.
What Is a DNS Leak?
A DNS leak happens when your device sends DNS requests outside the VPN tunnel instead of routing them through the encrypted VPN connection.
This means your internet provider or third parties may still see:
Websites you visit
Your browsing activity
Potential location data
Why DNS Leaks Are a Problem
DNS leaks reduce your privacy and weaken VPN protection.
Main risks:

You can test your VPN using online DNS leak test tools.
If your ISP or local DNS appears in results, your VPN is leaking DNS requests.
