DNS Leak

A DNS leak happens when queries go to your ISP or local network instead of through the VPN, exposing browsing Metadata. When in doubt, prefer simpler configurations: fewer exceptions, fewer custom routes, and verified leak-test results. If you travel often, this term becomes especially important because airports, hotels, and cafes are common interception points. For most people, the biggest privacy win is shielding activity from local network observers and reducing ISP-level profiling. VPN Surf and Elite VPN guidance aims to keep the concept actionable, not just theoretical.
