Question 1

What kinds of leaks can a VPN have?

Accepted Answer

The four common VPN leak types are: IP leaks (your real IP becomes visible), DNS leaks (queries go to your ISP), WebRTC leaks (a browser API reveals your real IP), and IPv6 leaks (IPv6 traffic bypasses an IPv4-only tunnel). A reputable VPN with kill-switch enabled blocks all four.

Question 2

What is a WebRTC leak?

Accepted Answer

WebRTC is a browser API for direct peer-to-peer communication. It can request your real public IP through STUN servers, bypassing your VPN. The fix is either to disable WebRTC in your browser, use a privacy extension that blocks STUN requests, or rely on a VPN that intercepts these calls.

Question 3

How often should I test for VPN leaks?

Accepted Answer

Run a full leak test every time you change your VPN server, switch protocols, update your VPN client, or move to a new network (especially public Wi-Fi). A VPN that protected you yesterday on Wi-Fi may leak today on a wired connection.
