Check If Your VPN Is Actually Working in 3 Seconds

IPok — Mon, 13 Apr 2026 12:24:34 +0000

You think your VPN is on. But is it really protecting you?

Most VPN users don't realize their DNS queries are still leaking to their ISP — even when the VPN shows "connected."

Two things you need to check:

1. DNS Leak Test — Are your DNS requests going through the VPN tunnel or your ISP?

2. WebRTC Leak Test — Is your real IP exposed through your browser's WebRTC?

Quick Test

👉 ipok.cc/en/tools/dnsproxy/ — Run the DNS Integrity Check

👉 ipok.cc/en/tools/webrtc/ — Run the WebRTC Leak Test

Both are free, run in your browser, and take about 3 seconds.

The Fix

If you see a leak:

Enable "DNS leak protection" in your VPN settings
Or manually set DNS servers (Cloudflare 1.1.1.1, Google 8.8.8.8)
Disable WebRTC in your browser settings

No signup. No ads. Just truth.

I Built a Free Privacy Checker That Detects DNS Leaks, WebRTC Leaks, and Browser Fingerprints

The Problem

Every time you browse the internet, your real IP address, DNS queries, and browser fingerprint are potentially exposed — even when you're using a VPN.

Most tools out there are either:

Paid
Cluttered with ads
Only checking one thing at a time

I built IPOK to solve this.

What is IPOK?

IPOK is a free, privacy-focused network diagnostics platform that checks:

Public IP address — What does the internet see when you visit?
DNS Leak Test — Is your VPN actually protecting your DNS queries?
WebRTC Leak Test — Is your real IP leaking through WebRTC?
TLS Fingerprint — How unique is your TLS handshake?
Browser Fingerprint — Canvas, WebGL, fonts, audio, storage
IP Type Detection — Is your IP a datacenter, VPN, or residential?

All in one place. No ads. No registration. Instant results.

Why I Built This

I wanted a tool that:

Works entirely in the browser (no server-side tracking)
Checks multiple privacy signals at once
Supports 4 languages (EN, 中文, 日本語, Русский)

Tools Overview

Network & Connectivity

DNS Lookup & Network Overview
DNS Integrity Check (multi-resolver consistency)
TLS Fingerprint & HTTP/3 Test
IP Type Detection (Datacenter/VPN/Proxy)
WebRTC Leak Test

Security & Privacy

Security Headers Test (CSP, HSTS, X-Frame-Options)
Browser Privacy Test (permissions & automation signals)
Browser Consistency Test (timezone, language, locale)

Browser Fingerprint

User Agent Parser
Canvas & WebGL Fingerprint
Browser Environment (fonts, audio, storage)
Browser Features Support

Open Source

The project is built with Next.js and deployed on Cloudflare, with a focus on privacy-first design. All checks run client-side — your data never touches our servers.
