DNS Leak Protection
Learn what DNS leaks are, how they compromise your privacy, and how EdgeVPN prevents them.
Understanding DNS Leaks
A DNS leak occurs when DNS queries bypass your VPN tunnel and go directly to your ISP's DNS servers, even though you're connected to a VPN. This exposes your complete browsing history to your ISP, defeating one of the primary purposes of using a VPN. DNS leaks can happen due to operating system configurations, IPv6 issues, or improper VPN setup. They're invisible to users but completely compromise privacy.
How DNS Leaks Happen
DNS leaks commonly occur when your device has multiple network adapters (WiFi, Ethernet, VPN) and the operating system doesn't correctly prioritize VPN DNS. Windows is particularly prone to DNS leaks. IPv6 connections can leak if the VPN only tunnels IPv4 traffic. Some malicious networks even force DNS queries to their servers. Without specific leak protection, VPNs may not handle these edge cases correctly.
EdgeVPN's DNS Leak Protection
EdgeVPN includes comprehensive DNS leak protection. We force all DNS queries through the VPN tunnel, not your ISP's servers. We handle IPv6 correctly by either routing it through the VPN or blocking it to prevent leaks. Our apps reconfigure system DNS settings to use only our secure DNS servers. This multi-layered approach ensures your browsing history remains private even in challenging network environments.
How It Works
Normally, DNS queries should route through your VPN's encrypted tunnel
A DNS leak occurs when queries bypass the VPN and go to your ISP
DNS leak protection forces all DNS through the VPN tunnel
Your ISP sees only encrypted VPN traffic, not individual website lookups
Key Benefits
- Prevents ISP from seeing your browsing history
- Maintains complete privacy even on problematic networks
- Protects against malicious DNS hijacking
- Ensures VPN protection extends to all DNS queries
- Peace of mind that privacy is maintained at all layers
Common Myths Debunked
DNS leaks only happen with bad VPNs
DNS leaks can occur even with quality VPNs due to operating system behaviors, network configurations, or IPv6 issues. Dedicated leak protection features are necessary to prevent them in all scenarios.
Using third-party DNS (like Google's 8.8.8.8) prevents leaks
Using alternative DNS servers doesn't prevent DNS leaks if queries still bypass your VPN. Only routing DNS through the VPN tunnel,or using encrypted DNS,provides real protection.
I can tell if I have a DNS leak by checking my connection
DNS leaks are invisible during normal use. Your VPN appears connected and working, but your browsing history leaks to your ISP. Only specific DNS leak tests reveal the problem.
Frequently Asked Questions
Everything you need to know about dns leak protection
Visit a DNS leak test website while connected to your VPN. It will show which DNS servers your queries use. If you see your ISP's DNS servers instead of your VPN's, you have a leak. EdgeVPN includes built-in leak protection to prevent this.
Common causes include: operating system default settings preferring ISP DNS, IPv6 connections not routing through VPN, multiple network adapters confusing DNS priority, and malicious networks forcing DNS queries to their servers.
Yes, EdgeVPN includes comprehensive DNS leak protection on all platforms. We force all DNS queries through the VPN tunnel, handle IPv6 correctly, and reconfigure system settings to prevent leaks in all scenarios.
Yes, mobile operating systems can also experience DNS leaks, especially when switching between WiFi and cellular networks. EdgeVPN's mobile apps include the same leak protection as desktop to prevent this.
An IP leak exposes your real IP address, revealing your location and identity. A DNS leak exposes your browsing history (which websites you visit). Both compromise privacy in different ways. EdgeVPN protects against both.
