DNS 泄露检测

检测你的 DNS 请求实际由哪些 DNS 服务器处理。如果你在使用 VPN,DNS 请求应走 VPN 的 DNS。

About This Tool

IP Address Lookup & Geolocation — Instantly see your public IPv4/IPv6 address, city, country, ISP and timezone. Useful for verifying your VPN or proxy exit node location.

WebRTC IP Leak Test & VPN Leak Check — Browsers can expose your real local IP via WebRTC even behind a VPN or proxy. This tool collects all ICE candidates and compares them against your HTTP exit IP to detect leaks.

User Agent Checker — What Browser Am I Using? — View your full User-Agent string and Client Hints (UA-CH) to identify your browser name, version, rendering engine and OS in one click.

Proxy & VPN Detector — Heuristically detect whether you are behind a proxy server or VPN by analyzing HTTP proxy headers (X-Forwarded-For / Via), IP risk scores and behavioral signals.

TLS Fingerprint (JA3 / JA4) — Collect TLS handshake characteristics server-side to generate JA3 hash and JA4 fingerprint, widely used in anti-bot and risk-control client identification.

Browser Fingerprint & Canvas Fingerprint Test — See how websites can track your browser without cookies using Canvas rendering, AudioContext and WebGL differences to build a unique device fingerprint.

DNS Leak Test — Check whether your DNS queries go through your VPN encrypted tunnel or bypass it and leak to your ISP, revealing your real location.

Screen Resolution & OS Detection — Check your device screen resolution, color depth, pixel ratio, operating system type and version, CPU architecture and hardware concurrency.

Frequently Asked Questions

What is my IP address right now?

As soon as the page loads, the "Public IP" card at the top automatically displays your current public IP address (IPv4 or IPv6), along with your city, country and ISP. If you are using a VPN, it will show the VPN exit node's IP address instead of your real one.

Can WebRTC leak my real IP address even with a VPN?

Yes — this is a well-known browser privacy risk. When a browser establishes peer-to-peer connections via WebRTC, it may expose your real local IP or ISP IP even if you are behind a VPN. This tool collects all ICE candidates and highlights any mismatch with your HTTP exit IP as a potential leak.

What browser am I using? How do I check my User Agent?

The "User Agent & Client Hints" section automatically displays your full User-Agent string, including browser name, version number, rendering engine and operating system. Client Hints (UA-CH) data is also shown where supported.

How do I test for a DNS leak?

A DNS leak occurs when your DNS queries bypass the VPN tunnel and go directly to your ISP's DNS server, revealing your true network location. This tool checks which DNS server resolves your queries and compares it against your VPN provider's expected location to detect leaks.

What is browser fingerprinting and how do websites track me?

Browser fingerprinting is the practice of collecting unique browser characteristics — Canvas rendering output, installed fonts, WebGL renderer, screen resolution, plugins and more — to identify you without cookies. Even if you clear your cookies, websites can still recognize you using these signals. This tool shows exactly what fingerprint data your browser exposes.

What is a JA3 / JA4 TLS fingerprint?

JA3 and JA4 are fingerprint hashes derived from TLS handshake parameters — cipher suites, extension list, elliptic curves and more. Security vendors and fraud-prevention systems use JA3/JA4 to identify scraping tools, malware or unusual clients even when the IP address changes.

How do I verify that my VPN is actually working?

This tool simultaneously checks your HTTP exit IP, WebRTC ICE candidate IPs and DNS resolver IP. If all three point to your VPN node's address, your VPN is working correctly with no leaks. If any one of them shows your real ISP IP, a leak exists — the most common being WebRTC leak and DNS leak. Open this page while connected to your VPN and compare all three values to instantly confirm whether your VPN is hiding your true IP address.

What is my IPv6 address? Can IPv6 bypass my VPN and leak my location?

The tool auto-detects and displays both your IPv4 and IPv6 addresses. Many VPNs only tunnel IPv4 traffic, leaving your IPv6 address exposed — this is called an IPv6 leak, and it can reveal your real ISP and location even while you think you're protected. If your VPN is configured correctly, the IPv6 address should also show the VPN exit node. If it shows your real ISP address, consider disabling IPv6 in your VPN client settings.

Is my IP address flagged as a proxy, VPN or on a blacklist?

The tool queries IP risk scoring services to check whether your current IP is classified as a data center IP, VPN exit node, Tor exit relay or known proxy. A risk rating is displayed so you can see how trusted or suspicious your IP appears to websites. If your IP is flagged in major risk databases, you may encounter CAPTCHAs or access restrictions on some sites — useful for cross-border merchants, marketers and developers who need to verify their IP reputation.

What information do HTTP request headers reveal about me?

Every time you visit a website, your browser automatically sends HTTP request headers including: User-Agent (browser and OS version), Accept-Language (language preference, hints at region), Referer (previous page), Cookie and any custom headers. Servers use these to build user profiles, detect bots and run fraud checks — even without you logging in. This tool shows you the complete set of request headers the server receives, so you can see exactly what you expose with every request.
