Your public IP address, shown large enough to read aloud. This is the one tool here that cannot run entirely in your browser — a browser genuinely does not know its own public IP, because the address is assigned upstream and rewritten by every NAT and proxy in between, so something on the network has to look at the request and tell you. Most sites answer that by calling a third-party API, which hands your address to a company you never chose to visit. This one asks this site's own server, which already saw your IP the moment it served you the page, so you give up nothing you had not already given up. Nothing is logged and nothing is stored. Underneath, the details your browser volunteers to every site it visits, so you can see what is on offer without anyone having to ask.
This tool does not use any data storage or network traffic.

Where this answer came from
This is the one tool on the site that cannot run entirely in your browser. A browser genuinely does not know its own public IP address — the address is handed out by your ISP and rewritten by every NAT and proxy between you and the internet, and nothing running in the page can see through that. Something on the network has to look at your request and report what it saw.
Most “what is my IP” sites answer that by calling a third-party API, which hands your address to a company you never chose to visit. There is no call here at all: this site's own server already saw your address the moment it served you this page, so it simply printed it. Nothing extra was requested, nothing was logged, nothing was stored, and nothing was passed on. No geolocation, no ISP lookup and no map either, because every one of those would need exactly the third-party database this tool exists to avoid.
What your browser tells every site
None of this needed asking for. Your browser volunteers all of it to every site you visit, this one included — it is read here in the page and goes nowhere.
