Frequently Asked Questions

What is a DNS leak in NordVPN?
A DNS leak occurs when your device sends DNS queries to your ISP's servers instead of NordVPN's secure DNS servers, potentially revealing your browsing activity and real location despite being connected to the VPN.
How do I know if NordVPN is leaking DNS?
Test for DNS leaks by visiting dnsleaktest.com while connected to NordVPN. If the results show your ISP's servers instead of only NordVPN servers, you have a DNS leak.
Does NordVPN kill switch prevent DNS leaks?
Yes, NordVPN's kill switch helps prevent DNS leaks by blocking all internet traffic when the VPN connection drops, ensuring no data bypasses the VPN tunnel including DNS queries.
Why does NordVPN DNS leak happen on Windows 10?
Windows 10's Smart Multi-Homed Name Resolution can cause DNS leaks by sending queries to multiple DNS servers simultaneously. Enable NordVPN's DNS protection to override this behavior.
Can I use custom DNS servers with NordVPN?
While possible, using custom DNS servers may increase leak risk. It's recommended to use NordVPN's built-in DNS servers (103.86.96.100 and 103.86.99.100) for maximum security and leak protection.
