01 / Live checks
Three ways a connection gives you away.
Each runs in your browser now. The IPv4 and IPv6 check asks ipify.org, and the WebRTC check asks a public STUN server (Google, Cloudflare), what they see.
WebRTC
Can a web page read your real address around the VPN?

IPv4 and IPv6
Do both kinds of address leave the same way?

02 / DNS leaks
Is your VPN hiding what you look up?
Every website you visit starts with a look-up. If those still go to your internet provider while the VPN is on, they get your browsing history anyway. The full test checks whether yours are filtered on the VPN or leaking, with a deeper WebRTC scan.
03 / Look something up
Any address, website or network.
That’s you, above. Try 1.1.1.1, itzgee.com or AS13335.
04 / In plain English
What all of this means.
Read as much or as little as you like.
What is an IP address?
It’s the return address for your internet traffic: the number websites reply to, the way a postal address is how a letter finds its way back.
The one above is your public address, the one the whole internet sees. It usually belongs to your internet provider and hints at roughly where you are, which is exactly what a VPN swaps out.
What is an ASN?
An ASN (autonomous system number) is an ID for a whole network. Every internet provider, cloud host and large company has one, like an area code for a piece of the map.
Yours shows who runs the network your address sits on. A home provider looks residential; a VPN or data centre looks like hosting, which is how tools tell the two apart.
VPN, proxy and Tor
A VPN encrypts everything and sends it through one server somewhere else, which replaces your address. A proxy reroutes one app, often without encryption.
Tor bounces your traffic through several volunteer relays so no single one knows both who you are and where you’re going. Strong privacy, slower speed.
WebRTC leaks
WebRTC lets browsers make voice and video calls and share files directly. To connect two people it has to find their real addresses, and a web page is allowed to ask.
So a script can sometimes read your real address even with a VPN on. Modern browsers hide your local one behind a .local name, but if a VPN is your privacy line, blocking WebRTC is worth it.
An address is not a location
There is no GPS behind an IP address. The “location” is simply where your provider registered that block of addresses.
That’s why it so often lands on a nearby city, the middle of the country or a data-centre town rather than your street. Good for “roughly which country”, misleading for anything closer.
Beyond the address
Hiding your address doesn’t make you invisible. Sites can still pick you out by browser fingerprinting: your screen size, system, fonts, time zone and graphics quirks stitched into a signature that is often unique, with no cookie needed.
A VPN changes where you arrive from. It does nothing about the fingerprint you bring with you.
Address details come from ipapi.is (through a server we run, so no key is sent to your browser) and ipwho.is. Nothing you look up here is kept by this page.
