This is the public address your internet provider has assigned to your connection. Every website you visit can see it.
Network details come from a public address registry. Device details are read from your browser and never leave it.
It is the address your internet provider assigns to your connection, and it is how the rest of the internet reaches you. Servers you connect to see this address rather than the individual devices behind it.
Addresses like 192.168.1.10 or 10.0.0.5 are private. They exist only inside your own network and are not routable on the internet. Your router translates between the private addresses on your devices and the single public address shown above.
Usually, yes. Most residential and small business connections use dynamic addressing, so the address can change when your modem restarts or the lease renews. A static address stays fixed and is normally a paid add-on from the provider. If you host anything on site, a static address is often worth having.
Geolocation maps an address block to wherever the provider registered it, which is frequently a regional facility rather than your building. Being off by a city, or landing on your provider's headquarters entirely, is normal and not a sign of anything being misconfigured.
Every site you visit already receives it, so it is not secret. It does not reveal your name or street address on its own, though your provider can tie it to an account. A VPN replaces it with the address of the VPN server.
