“They can find your address from your IP.” Most people have heard some version of it. So how much is actually knowable?
The short answer: not your address. But “nothing at all” is wrong too, and the space between those is where the misunderstanding lives. So — two columns.
Why it stops at “roughly there”
Providers receive addresses in blocks and hand them out to customers. What can be traced from outside is therefore which provider owns a range, and no more. Any location attached to it is inferred from where that provider’s equipment sits.
So a provider headquartered in one city will place you in that city even when you live elsewhere. Services that name a district are common, and being wrong is unremarkable for them.
Your address changes
Home connections rarely have a fixed address. Restart the router, or leave it offline a while, and it may differ afterwards. A different number today is normal — not a fault, and not a sign of anything being compromised.
Everything in the house — laptops, phones, the television — also leaves through the same public address. The `192.168.…` numbers you see in settings are internal to your home and invisible from outside.
Checking your own
Your public address is not visible to the browser. Only the side receiving the connection can see how you appear. Opening this site’s IP address check shows exactly that.
That page keeps what the server saw separate from what your device reported about itself, so you can read straight off which facts travelled. It also tells you whether you are now arriving over IPv6.
What a VPN changes
Through a VPN, the other end sees the VPN operator’s address instead of yours — so your provider is hidden. But the operator can see what you hid, which means you have changed who you are trusting, not removed the need to trust anyone. That is why free VPNs are hard to recommend.
A side effect: on a VPN, the time zone implied by your IP and the one your device is set to stop agreeing. The IP check shows both side by side, which makes it a useful hint — though travelling, or a hand-set clock, looks identical, so it is not proof.
In short, an IP address indicates which provider, and roughly which region — no more and no less. Not worth being frightened of, and not quite anonymous either. Somewhere in between is the right distance to keep.
