This is the address our server sees on the connection you just made, which is the address the rest of the internet sees too. It is not the 192.168 number your router assigned you, and the two are answers to different questions.

How to use

Nothing to enter. The page reports the source address of the request it received. Toggle your VPN and reload to watch the value change.

Two addresses, and only one of them is public

Your device holds a private address handed out by your router, usually starting 192.168 or 10. That number is meaningful inside your home and invisible outside it. Everything you connect to sees a different address, the one your router presents on behalf of every device in the house. This page reports the second, because it is the one that appears in other people's logs.

When the answer arrives in IPv6

A connection that could use either protocol will often choose IPv6, and the result is a long hexadecimal address rather than four familiar numbers. Both are your public address, they are simply different networks reaching the same place. If a service is expecting a v4 address from you and getting a v6 one, that mismatch is frequently the actual bug behind a whitelist that stopped working.

Confirming a VPN is carrying your traffic

The reliable test is a before and after. Load the page with the tunnel down, note the address, bring the tunnel up, and reload. An unchanged value means the traffic is not going through it, regardless of what the client says. This catches split tunnelling, a dropped connection that failed open, and a browser extension that only proxies some requests.

FAQ

Am I looking at IPv4 or IPv6?

Whichever your connection actually used. Networks that support both will often prefer IPv6, which is why the answer here can look nothing like the address you expected.

Why does my phone show something different?

Mobile data leaves through your carrier's network, and home Wi-Fi leaves through your ISP. Different paths, different public addresses, both correct.

Is my browsing being logged?

The address has to be seen to be displayed, which is true of every request you make anywhere. Nothing is kept as a profile and the page shows the current value only.

The address did not change after I connected to a VPN.

Either the tunnel is not up or it is not carrying this traffic. Split tunnelling in particular routes some applications outside the VPN, and a browser is a common exception.
