Browser Signals

Proxy leak consistency checks

These checks run locally in your browser. They help compare your visible IP location with device-level hints such as timezone, language, cookies, and WebRTC behavior.

Browser Timezone

Detecting...

A timezone far from your VPN country can make a masked connection look inconsistent.

Browser Language

Detecting...

Language preferences can be used as a soft regional hint.

Cookies

Detecting...

Cookies can identify repeat visits even when your IP address changes.

WebRTC

Checking...

Some browsers expose local or network candidates through WebRTC.

DNS leak check: browsers do not expose DNS resolver details directly to page JavaScript. If your VPN provides DNS leak protection, use this page together with your VPN app status and compare your visible IP before and after reconnecting.

FAQ

Proxy Check FAQs

01 How do I know if an IP address is a proxy?

A proxy check reviews the direct proxy indicator associated with the visible IP address.

02 Why does a proxy check say not detected when I use a proxy?

Some proxy IP addresses are not labeled in every database. Compare your IP, location, ASN, ISP, and network type before and after connecting to confirm whether traffic changed.

03 Is a datacenter IP always a proxy?

No. This page now reports proxy detection only from the direct proxy signal, not from datacenter or hosted-network classification.

04 Can websites block proxy IP addresses?

Yes. Some websites block or challenge traffic from known proxies or networks with elevated fraud signals.
