Your IP address: what it actually is
Every device connected to the internet has a public IP address — a number assigned by your ISP that identifies your connection on the global network. Think of it like a postal address for your internet traffic. When you visit a website, your IP address goes along with every request so the server knows where to send the response.
The question is: what can someone do with that number?
What your IP address reveals
Your ISP
The most reliably accurate piece of information an IP lookup returns. Your ISP owns the block of IP addresses that includes yours. This is always accurate — it's how IP routing works at a fundamental level.
Your approximate location
IP geolocation can typically determine your country with 99% accuracy, your region or state with about 80% accuracy, and your city with about 60–70% accuracy. Notice "approximate" and "city" — not your street, not your building, not you specifically. What IP geolocation actually finds is the location of your ISP's nearest infrastructure node or data centre, which may be in a different city from where you actually are.
Your ASN (Autonomous System Number)
Your ASN identifies the network organisation that owns your IP block — usually your ISP, a cloud provider, or a large company. This is useful for diagnosing routing issues and understanding network ownership.
Whether you're using a VPN
VPN IP ranges are often in public databases. Many IP lookup tools — and many websites — can detect that an IP belongs to a known VPN provider. If you're trying to appear local for a streaming service, this detection is often why it fails.
What your IP address does NOT reveal
- Your name — ISPs don't publish subscriber information publicly
- Your exact address — geolocation resolves to city level at best
- Your device — an IP is shared by your entire household's internet connection
- Your browsing history — that's stored by your browser and ISP, not visible from the IP alone
- Your identity — without a court order to your ISP, an IP address cannot be linked to a real person
Should you be worried about your IP being known?
For most people in most situations: no. Your IP address is shared with every website you visit, every online game server you connect to, and every API call your apps make. It's a routine part of how the internet works.
The cases where it matters more: if you're a journalist or activist in a repressive country, if you're trying to bypass geographic restrictions, or if you're being actively targeted by a sophisticated threat actor. In those cases, a reputable VPN is the appropriate tool.
