What Is a DNS Leak?
Understand DNS leaks, how they expose browsing requests, and how to test VPN DNS protection before trusting a provider.
- Fastest protocol coverage (WireGuard + OpenVPN).
- Global server footprint and anti-censorship resilience.
- Strong no-logs and leak protection posture.
Quick Answer
Understand DNS leaks, how they expose browsing requests, and how to test VPN DNS protection before trusting a provider.
Quick Comparison
A DNS leak happens when your device sends domain lookup requests outside the VPN tunnel, often to an ISP or local network resolver.
Run DNS leak tests before and after connecting, then switch networks and servers to see whether the same private DNS behavior remains stable.
Good VPN apps should route DNS through their encrypted tunnel and avoid exposing ISP resolvers during reconnects or split tunneling.
Entity Layer
OpenVPN
Open-source protocol widely used for secure tunnels.
AES-256
Strong encryption standard used for VPN transport security.
DNS Leak Protection
Prevents DNS requests from exposing browsing activity outside the VPN tunnel.
Split Tunneling
Lets users choose which traffic goes through VPN and which goes direct.
ISP Throttling
Bandwidth slowdowns by internet providers based on traffic type.
Geo-blocking
Regional content restrictions often used by streaming platforms.
No-logs Policy
Provider commitment not to retain activity logs tied to users.
Frequently Asked Questions
What is the best VPN for VPN in your country?
NordVPN is the top all-around option in our latest benchmark cycle for speed, stability, and privacy controls.
Can a VPN improve streaming and gaming quality?
A VPN can improve route quality in some regions, reduce throttling, and maintain safer public-network sessions.
Which protocol should I choose first?
WireGuard is usually fastest, while OpenVPN remains broadly compatible across older setups.
