What Is My IP Address? IPv4 and IPv6, Free and Private
See your public IPv4 or IPv6 address in one click, plus your browser, operating system, screen size, time zone and language. The address is shown back to you and never stored.
Your public IP address
The address is read from your request, shown back to you here and not stored or logged.
What your browser reports
These details are read in your browser and never sent anywhere.
About What Is My IP
What Is My IP shows the public IP address that websites see when your device connects to them, together with the facts your browser already knows about itself. Open the page and the address appears within a moment, labelled IPv4 or IPv6, with a Copy button beside it. Below it you will find your browser and operating system, your screen size and pixel ratio, your time zone and your language settings. There is nothing to type and nothing to install.
Here is exactly what leaves your device and what does not. To learn your address, the page sends one ordinary request to our own server, which reads the address the request arrived from and sends it straight back to you. We do not store that address and we do not write it to our logs. Everything else on the page, such as the browser name, screen size and time zone, is read inside your browser and is never sent anywhere.
How to use it
Steps
- Open the page. Your public address is looked up automatically, once.
- Read the address and its version badge. Press Copy to put it on the clipboard.
- Check the browser details if you need them for a support request, a bug report or a firewall rule.
- Change network, for example from Wi-Fi to mobile data or a VPN, then reload the page. The address changes with the network.
What an IP address is
An IP address is the number that identifies your connection on the internet. Your home router or your mobile network hands out one public address, and every device behind it shares that address when talking to websites. That is why two phones on the same Wi-Fi show the same result here.
IPv4 addresses are four numbers from 0 to 255 separated by dots, such as 203.0.113.9. There are about billion of them, which is fewer than there are people online, so many providers share one address between many customers. IPv6 addresses are eight groups of hexadecimal digits, such as 2001:db8::1, where :: stands for a run of zero groups. They allow addresses, enough for every device to have its own. If your network supports both, the page shows the one your browser used to reach us.
What the browser details mean
Browser and operating system
Read from the user agent string your browser sends with every request. The parser recognises Chrome, Edge, Firefox, Safari, Opera and Samsung Internet, and Windows, macOS, iOS, iPadOS, Android, ChromeOS and Linux. Browsers now freeze parts of that string for privacy, so a recent Mac may still say macOS without a version.
Screen size and pixel ratio
The size is in CSS pixels, the unit web pages use, not in physical pixels. A ratio of 2 means each CSS pixel is drawn with a 2 by 2 block of device pixels, which is typical for sharp phone and laptop screens.
Time zone and language
The time zone is the IANA name, for example Europe/Berlin, followed by the current offset from UTC. Language lists the preferred languages set in your browser, in order.
Worked examples
A request that reaches our server through the hosting proxy carries the header x-forwarded-for: 203.0.113.9, 10.0.0.2. The first entry is the visitor, so the page shows 203.0.113.9 and the badge IPv4. If the proxy sends [2001:db8::1]:443, the brackets and port are removed and the page shows 2001:db8::1 with the badge IPv6. An IPv4 address written in IPv6 form, ::ffff:203.0.113.9, is shown as plain IPv4.
Limits
The page shows your public address as the internet sees it, not your private address such as 192.168.1.20. It does not tell you where you are: the address says which network you are on, not your street. If you use a VPN, proxy or Private Relay, the address shown is theirs, which is a quick way to check the VPN is working. If the lookup fails, for example because you are offline, the page says so and offers Try again.
Frequently asked questions
Does this page store or log my IP address?
No. Our server reads the address your request came from, sends it straight back to you and forgets it. It is not written to a database or to our logs, and the response is marked so that browsers and caches do not keep it.
What is the difference between IPv4 and IPv6?
IPv4 uses four numbers separated by dots, such as 203.0.113.9, and allows about 4.3 billion addresses. IPv6 uses eight groups of hexadecimal digits, such as 2001:db8::1, and allows vastly more. The badge shows which one your browser used to reach this page.
Why does the page show a different address on my phone and my laptop?
They are probably on different networks, for example mobile data and Wi-Fi. Devices on the same Wi-Fi share one public address, so they show the same result. A VPN or Private Relay also replaces your address with its own.
Does my IP address reveal my exact location?
No. It identifies the network you are using, which usually maps to a region or city at best, and a mobile network or VPN can place you far away. This page does not look up a location at all; it only shows the address.
Why is the page showing my VPN's address and not mine?
Websites only see the address of the last hop. With a VPN, proxy or Private Relay switched on, that is the provider's address. It is a quick way to confirm the VPN is working: the address should change when you turn it on.
Which of my browser details leave my device?
None of the details listed below the address. Browser, operating system, screen size, pixel ratio, time zone and language are read inside your browser and shown on the page. Only the single request that asks for your public address is sent to our server.
