How to use it
- Open the page. Your public IP address appears at the top within a second or two.
- Press Copy to copy it, for example to send to IT support or add to an allow list.
- Look at the table to see the other details your browser shares with websites.
What you’re seeing
| Detail | What it means |
|---|---|
| Public IP address | The address websites see when you connect. It usually belongs to your internet provider or mobile network. |
| Version | IPv4 (like 203.0.113.45) or the newer IPv6 (like 2001:db8::1) |
| Browser language | The language your browser asks websites for |
| Time zone | From your device settings |
| Screen | Your screen size in pixels |
| Browser | The user agent: your browser, its version and your operating system |
IPv4 or IPv6?
| IPv4 | IPv6 | |
|---|---|---|
| Looks like | 203.0.113.45 | 2001:db8:85a3::8a2e:370:7334 |
| Number of addresses | About 4.3 billion | Practically unlimited |
| Shared? | Often shared by many homes or phones | Usually unique to your connection |
The world ran short of IPv4 addresses, so many providers share one IPv4 address between lots of customers. IPv6 fixes that, and a growing share of users now reach Google over IPv6, according to Google’s own figures. Which one you see depends on your provider and network.
Public and private addresses
Your router gives each device at home a private address, usually starting 192.168 or 10. Those only work inside your network. The outside world sees one public address for the whole home. That’s the one this tool shows.
Why your IP address changes
- Home broadband: many providers change it from time to time or when the router restarts. A fixed (static) IP is usually an extra.
- Mobile data: it can change often, and many phones share one address.
- Wi-Fi vs mobile: switching between them changes your IP straight away.
- VPN: websites see the VPN’s address instead of yours.
What an IP address does and doesn’t reveal
An IP address shows roughly where your provider connects you to the internet, often the town or region, but usually not your street or home. Your provider can link it to your account, which is why the UK’s Information Commissioner’s Office lists IP addresses among the online identifiers that may be personal data.
- Every website you visit can see your IP address. That’s how the internet sends pages back to you.
- This tool shows it only to you and doesn’t store it.
- To hide it from websites, use a trusted VPN.
When you might need it
| Situation | Why |
|---|---|
| IT support | To check your connection or unblock you |
| Work systems | To add your home IP to an allow list for remote access |
| Games and servers | To let friends connect or set up port forwarding |
| Checking a VPN | To make sure your real IP is hidden when the VPN is on |
| Email problems | To check whether your address is on a blocklist |
Checking a website rather than your own connection? Try the website technology lookup or the domain age checker.
Frequently asked questions
What is my IP address?
It’s shown at the top of this page: the public address websites see when you connect.
What is the difference between IPv4 and IPv6?
IPv4 addresses are four numbers like 203.0.113.45. IPv6 is newer, longer and has far more addresses.
Can someone find my home from my IP address?
Usually only your rough area. Your provider can link it to your account, but it doesn’t share that publicly.
Why does my IP address keep changing?
Most providers use dynamic addresses that change over time or when your router restarts.
How do I hide my IP address?
Use a trusted VPN. Websites then see the VPN’s address instead.
Is an IP address personal data?
It can be. The ICO lists IP addresses as online identifiers that may be personal data.
Do you store my IP address?
No. It’s shown only to you and isn’t stored.
