A web page that tells you what your browser gave away the moment you arrived. No login, no form, no permission. Most pages do this. None of them tell you.
The point is not that they know your IP, but that even your IP already gives away information. That’s why they start with the information, rather than the IP being the source.
This is not intended to be for people who understand how this works.
The public IP is irrelevant, only shows the IP of the server used by your ISP, which can be at the other side of the country. It can maybe identify the ISP, but not the user, less if a dynamic changing IP is used. The public IP is always leaked if you don’t use a VPN or the TOR network.
Absolutely not, the public IP a website sees is your home IP. The resolved location will be inaccurate by design, but the IP definitely identifies you at that time.
What the website see is the current IP of the used ISP server in this moment. In the last check it was Madrid, several hundreds km from my real home. The public IP isn’t the same as my user IP, which only know my ISP and I (and the police by the ISP, if exist a court order). The public IP don’t show your real location, the website only can use your GPS data if you have it activated or if it appears in your account data (Google, Google Maps).
Depending on your location it can actually be geolocated into your specific city block, I geolocated an online friend’s IP just for the hell of it (I already knew where they lived) and it spit back out the city block they lived in as well as a lot of other very identifiable information
Also, if you can ping devices on that network using that IP you can also use that as a way to easily identify users. That’s if they have anything that isn’t firewalled, obviously, but the point stands!
I understand how all of it works. Whether it’s vibe coded or not it, it showed me stuff that I didn’t think about like arbitrary web pages can know my phone tilt, battery level??
“We know your IP address”. No kidding, that’s how IPv4 works, even if the browser wasn’t

And as someone else said, probably vibe coded.

depends on the isp, my router has its own adress on the iternet
couple of friends have a different isp that layers it users behind multiple nats so half the city would show the same ip on a website

The opsec implications are severe.
Oh yeah, it’s insane. The only way to truly protect your identity on the internet is by not using the internet. Second best would be tor, I suppose
