Toolbox

Free network diagnostic and privacy tools for checking IP addresses, VPN leaks, connection speed, DNS behaviour, browser privacy, and connection exposure.

Tool order

Start with your IP, then check leaks

Your public IP address is the first signal websites can see, but it is not the only one. DNS requests, WebRTC behaviour, browser fingerprints, user-agent details, and network latency can all reveal different pieces of information.

If you are checking a VPN, start with your visible IP address, then run DNS and WebRTC leak checks. If you are worried about tracking, add the browser fingerprint and user-agent checks because a VPN does not hide every browser-level signal.

Privacy

VPN Check

Check whether your visible IP, ISP, location, and VPN/proxy signals change when your VPN is connected.

 Privacy

Proxy & VPN Check

Check whether your visible IP looks like a VPN, proxy, datacentre, or Tor exit, and whether it has an abuse history.

 Privacy

Network Leak Check

See the IP, ISP and location sites can see, and whether a public IPv6 address is bypassing your VPN.

 Browser

WebRTC Leak Test

Detect whether your browser can expose local or public IP details through WebRTC.

 Browser

Browser Fingerprint Test

See which browser, device, screen, canvas, WebGL, font, and TLS handshake signals websites may use to recognise you.

 Browser

User Agent Checker

View your raw user agent, detected browser, device hints, and selected HTTP request headers.

 Network

Speed Test

Test your internet connection speed and understand what affects real-world performance.

 Network

Ping Test

Measure latency to understand delay, jitter, and connection responsiveness.

 Network

Port Checker

Check whether a port appears reachable from the public internet.

 Lookup

IP Geolocation

Look up approximate geographic and network details for a public IP address.

 Lookup

IP WHOIS Lookup

See which organisation and network an IP address is registered to, with its range, allocation type and abuse contact.

 Lookup

Reverse DNS Lookup

Find the hostname an IP address resolves back to, and see the PTR record it was looked up under.

 Privacy

Data Breach Check

Check whether an email address has appeared in a known data breach, without ever logging or storing it.

Common tool workflows

These workflows connect multiple tools together so you can answer a specific privacy or network question instead of checking pages at random.

Check whether your VPN is working

  • Check your visible IP
  • Run Network Leak Check
  • Run WebRTC leak test
  • Review browser fingerprint

Understand why a location looks wrong

  • Check IP geolocation
  • Compare ISP and region
  • Read the location accuracy guide

Review browser privacy exposure

  • Check browser fingerprint
  • Check user agent
  • Check WebRTC exposure

Why results can vary between tools

IP and network tools rely on different data sources. One provider may show your ISP routing point, another may show a nearby city, and a VPN may show the server location instead of your physical location. Treat location results as approximate.

Browser-based checks can also vary depending on your browser, extensions, operating system, VPN settings, and whether private browsing or tracking protection is enabled. Re-run the tools after changing privacy settings so you can see what changed.
