Does this one send anything over the network?

Yes, and it has to. What Is My IP cannot answer without making a request, so it sends a request from your connection to ipapi.co. That request is how your public address is discovered. Your own browser cannot see it. Nothing else about your session goes with it, and no copy is kept here, because DevToolbox still has no backend.

Where does the IP address come from?

Your own browser cannot see your public address. Only a machine on the other side of your router can. This tool asks ipapi.co, which reports the address your request arrived from along with its rough geolocation. That request is the one exception to the site's no-network rule, and it is the whole point of the tool.

What is read locally?

Everything except the IP block: platform, languages, time zone, screen and viewport size, hardware concurrency and connection state all come from the browser's own APIs. That is also the point: it is the same surface any site can read about you without asking.

What Is My IP: Public IP & location. A free browser-based tool from DevToolbox, with no account and no tracking. It is one of the seven that has to use the network: it sends a request from your connection to ipapi.co.

Show your public IP address and what your browser reveals about itself: platform, languages, time zone, screen and viewport, hardware concurrency and connection state.
