What is an IP address? (and what it actually reveals about you)
A plain-English guide to the number that identifies your device on the internet.
The basics
An IP address (Internet Protocol address) is a unique label assigned to your device so the internet knows where to send the data you ask for. When you load a website, your request travels out with your IP attached — like a return address on an envelope — so the response knows how to find its way back. Without one, your device couldn't communicate online at all.
Public vs. private — two different addresses
Most people have two IP addresses, and confusing them causes a lot of misunderstanding:
- Your public IP is the address the outside internet sees. It's assigned by your internet provider (ISP) and shared by every device on your network. This is the one shown at the top of this page.
- Your private IP is what your home router assigns to each device inside your network (your laptop, phone, TV). These usually start with 192.168. or 10. and never leave your network.
So when a website "sees your IP," it sees your public one — your router's address, not your individual device.
What your public IP actually reveals
This is where honesty matters, because it's often over- and under-stated:
- Your ISP — the company providing your connection is usually identifiable from your IP.
- A rough location — typically your city or region. Crucially, this is an estimate, not GPS. IP geolocation is frequently off by a wide margin, sometimes placing you in the wrong city, state, or even country. Any site (including this one) that shows your location from your IP is making an educated guess.
- What it does not reveal: your name, your street address, your specific device, or what you're doing online. Your IP alone can't identify you personally — that requires information your ISP holds and doesn't hand out without legal process.
Why it changes
Most home IPs are dynamic — your ISP rotates them periodically, so yours may differ week to week. Some connections have a static (fixed) IP, more common for businesses. Either is normal.
IPv4 and IPv6
You may see two formats. IPv4 looks like 192.0.2.146 — four numbers separated by dots. IPv6 is longer, like 2001:0db8:85a3::8a2e:0370:7334, and exists because the world ran out of IPv4 addresses. We cover the differences in detail in our IPv4 vs IPv6 guide.
Can you hide it?
Yes — a VPN or proxy replaces your visible public IP with the server's, so sites see that address instead of yours. It's the most common way to mask your IP and rough location. (See our guide on hiding your IP for the honest version of what that does and doesn't protect.)
