IP results — How to read them

Pass: The shown IP belongs to your VPN server/location. Fail: It shows your ISP/home/office IP.

  • Fix fast: Enable kill switch, switch protocol (WireGuard/OpenVPN), reconnect to a different server, update the VPN app.
  • IPv6 tip: If unsupported by your VPN, disable IPv6 at OS level to prevent bypasses.

DNS results — How to read them

Pass: DNS resolvers are your VPN’s. Fail: Resolvers belong to your ISP or unrelated providers.

  • Fix fast: Turn on your VPN’s DNS leak protection. Clear DNS cache. On Windows, disable Smart Multi‑Homed Name Resolution; ensure no split‑tunnel app bypasses DNS.
  • Alternative: Use your VPN’s DNS or DoH/DoT inside the tunnel (not system/ISP DNS).

WebRTC results — How to read them

Pass: No non‑VPN IPs are revealed via WebRTC. Fail: WebRTC exposes a local or public IP outside your VPN.

  • Fix fast: In the browser, disable WebRTC leaks (built‑in flags or privacy extensions), ensure the VPN kill switch is on, and retest.
  • Tip: Different browsers handle WebRTC differently — retest after any browser change.

Speed/latency — Interpreting results

  • What’s normal: +10–30% latency vs no‑VPN; some throughput loss is expected.
  • Optimize: Switch to the nearest server, try WireGuard, avoid congested locations, and verify no other apps are saturating bandwidth.

FAQ

My VPN is connected but I still fail the IP test — why?

Likely causes: brief reconnection without kill switch, IPv6 bypass, split‑tunneling misconfig, or a buggy server. Enable kill switch, switch protocol/server, and retest.

Do I need to worry about IPv6?

Yes if your VPN doesn’t support it. Either use a VPN that fully handles IPv6 or disable IPv6 at the OS until supported.

Which VPNs avoid leaks consistently?

Consistency depends on client versions and settings. See our top picks below and always retest after changes.
