What is my IP address?
This is the address every website sees when you visit it, and next to it what websites see instead when you open them through OnlineProxy.eu. Below: what an IP address is, what it reveals about you and how to hide it.

What is an IP address?
An IP address (Internet Protocol address) is the number that identifies a connection on the internet. Every piece of data your device sends carries it as the sender, so that the answer knows where to go, just like the return address on a letter.
Your internet provider gives your connection a public IP address. Every website, app and online service you use sees it, and many of them store it.
IPv4 and IPv6
Two versions are in use today, often side by side on the same connection:
| IPv4 | IPv6 | |
|---|---|---|
| Example | 203.0.113.42 | 2001:db8:85a3::8a2e:370:7334 |
| Format | Four numbers from 0 to 255 | Eight groups of hexadecimal digits, with runs of zeros shortened to :: |
| Number of addresses | About 4.3 billion | About 340 undecillion, enough for every device |
| Today | Used up: many customers often share one address | Growing: most large websites and mobile networks support it |
Which version a website sees depends on whether your connection and the website both support IPv6. The box above shows the one your browser used to reach us.
Public and private IP addresses
The public address belongs to your router. Inside your home, the router gives each device its own private address, usually starting with 192.168 or 10. Private addresses only work inside your own network: everything that leaves it carries the router's public address.
That is why the address on this page differs from the one in your computer's network settings: those show the private address.
What your IP address reveals
| Information | Revealed by your IP address? |
|---|---|
| Your country | Yes, almost always correctly |
| Your region or city | Roughly, and often off by many kilometres |
| Your internet provider | Yes |
| Your name and street address | No. Only your provider knows which customer had an address at a given time. |
| The websites you visit | No, but each of them sees your address |
Websites use your address to choose a language and currency, to show or block content by country (geo-blocking), to fight spam and fraud, and, together with cookies, to recognise you on your next visit.
Who can see your IP address?
- Every website you visit, and the advertising and analytics services built into it.
- The apps and games on your devices, for every connection they make.
- Your internet provider, which assigned the address and keeps records of who used it.
- Anyone you connect to directly, for example in some online games or file-sharing programs.
Through a web proxy, websites see the proxy's address instead of yours, while the proxy's operator still sees yours. More on this in what a web proxy hides, and from whom.
Why does my IP address change?
Most home and mobile connections get a dynamic address: the provider assigns one from its pool, and it can change when your router restarts, after a set time, or when you reconnect. On mobile data, many customers often share a single address. Companies and servers usually have a static address that stays the same.
Your address also changes whenever you use another network: at school, at work, on public Wi-Fi or on mobile data, websites see that network's address.
How to hide your IP address
Websites only see your address because you connect to them directly. To hide it, connect through a service in between: the website then sees the service's address.
| Method | What websites see | Effort |
|---|---|---|
| Web proxy | The proxy's address, for the websites you open through it | None: works in the browser |
| VPN | The VPN server's address, for everything on your device | An app, mostly paid |
| Tor Browser | The address of a Tor relay, which changes regularly | A separate browser, slow |
| Another network | That network's address | Changes your address, but does not hide you |
The differences between these tools are explained in proxy, VPN or Tor.
How to find your IP address on a device
This page shows your public address. Your device's private address is in its network settings:
- Windows: type
ipconfigin the Command Prompt. - macOS: hold the Option key and click the Wi-Fi icon in the menu bar.
- Linux: type
ip addrin a terminal. - Android, iPhone and iPad: open the Wi-Fi settings and the details of your network.
Questions and answers
Is my IP address personal data?
In the EU, it can be: the Court of Justice of the EU has ruled that an IP address is personal data when it can be linked to a person, for example through the provider. That is why the GDPR applies to it.
Can someone find my home address from my IP address?
Not from the address alone. Lookup services only show a rough location, often just your provider's city. Only your provider knows which customer used an address, and it hands that over only when the law requires it, for example to the police with a court order.
Why does this page show the wrong country?
Location databases are sometimes wrong or out of date, especially for mobile networks, company networks and newly assigned addresses. If you use a proxy, a VPN or Tor, you see that service's address and location.
Why does my IP address keep changing?
Most providers give home and mobile connections a dynamic address that changes now and then. That is normal and does not mean that anything is wrong.
Does a proxy hide my IP address from everyone?
It hides it from the websites you open through it. The proxy's operator, your internet provider and websites you open outside the proxy still see it.
Is it legal to hide my IP address?
In most countries, yes: proxies, VPNs and Tor are legal tools. What you do with them has to be legal too.
