My IP address doesn't show the right location anymore?

You belong to your iSP's 'Network' composed of all their customers.
They have several major hardware centers widely spread out, where they have rooms of servers, (and in many cases dedicated companies handle several iSP's; called "Multihoming" https://en.wikipedia.org/wiki/Multihoming ) handling all their traffic.
If during the day or night a server breaks down, or there's a sudden surge of traffic volume, they automatically would spread traffic across the rest of their servers to achieve 'load balancing'.
Once thru their hardware, your traffic exits the iSP server(s) onto the 'Net.
This is your Public iP that other devices on the 'Net 'see' and direct requested traffic to.

"Lookup" services see your Public iP server, which may be many kilometers distant from your physical location.
