How to use the what is my ip address?
What it calculates and when to use it
Shows the public IP address that websites see when you connect, both IPv4 and IPv6 if you have them, together with your browser, operating system, language, time zone and connection type. An optional lookup adds the approximate city, country and internet provider. Use it to check a VPN, set up remote access, whitelist yourself on a firewall or give support your address.
How to use it, step by step
- Open the page. Your address appears straight away, with nothing to type.
- Read your IPv4 and IPv6 addresses in “Your addresses”. “Not detected” for IPv6 means your connection does not offer it.
- Press “Show approximate location and provider” if you want the city, country and provider.
- Press “Copy result” to copy your address, or “Check again” after switching a VPN or network.
What each input means
- Nothing to enter – The address is read from your connection when the page opens.
- Check again – Repeats the lookup after you change network, turn a VPN on or off, or move from Wi-Fi to mobile data.
- Show approximate location and provider – Optional. Sends your address to a third-party lookup service only when you press it.
How to read the results
- Your public IP address – The address your connection presents to the internet, shown as IPv4 or IPv6.
- IPv4 and IPv6 address – Both versions, when your network supports them.
- Browser and device – Browser, operating system, language, time zone, screen size and connection type as your browser reports them.
- Approximate location and provider – City, region, country and internet provider for the address, if requested.
The formula
No calculation. An IPv4 address is four numbers from 0 to 255 separated by dots, for example 203.0.113.25, which is a 32-bit number. An IPv6 address is eight groups of hexadecimal digits separated by colons, a 128-bit number. About 4.3 billion IPv4 addresses exist, which is why most homes share one.
A worked example
A laptop on home Wi-Fi shows 203.0.113.25 as its public IPv4 address, and the same address appears for the phone and TV on that network. The laptop’s local address, such as 192.168.1.20, is private and is not shown to websites. After turning on a VPN and pressing “Check again”, the page shows the VPN server’s address instead.
Assumptions and limits
- The address shown is the one the page’s server or lookup service receives. Behind a VPN, proxy or office network it is that gateway’s address.
- Location is estimated from address databases and is often only accurate to the city or region, and sometimes wrong.
- Browser details are what your browser reports and can be changed by privacy settings or extensions.
Common mistakes
- Confusing the public address with the private one such as 192.168.x.x, which only works inside your home or office network.
- Expecting the location to be your street address. It usually points to your provider’s nearest hub.
- Forgetting to press “Check again” after switching a VPN, so you still see the old address.
- Blocking the lookup with a content blocker and reading “could not be found” as a fault.
Frequently asked questions
What is an IP address?
An Internet Protocol address is a number that identifies a connection on the internet, so replies to your requests come back to the right place. It works like a postal address for data.
What is the difference between a public and a private IP address?
A public IP address is the one your provider gives your connection and websites can see. A private address, such as 192.168.1.20, identifies a device inside your home or office network and is not visible on the internet. Your router translates between them.
What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses written as four numbers, and the supply is nearly exhausted. IPv6 uses 128-bit addresses written in hexadecimal, with a practically unlimited supply. Many connections have both.
Why does my IP address show a different country or city?
Location is guessed from databases that map address ranges to providers. Providers often route traffic through a hub in another town, and a VPN or mobile network can place you in another country.
Can someone find my home address from my IP address?
No. An IP address alone reveals roughly your region and provider, not your street. Only your provider can link it to your account, and normally only on a legal request.
Does a VPN change my IP address?
Yes. While the VPN is connected, websites see the VPN server’s address instead of yours. Press “Check again” to confirm.
How do I change my public IP address?
Restarting your router can give you a new address if your provider assigns them dynamically. A VPN, a different network or mobile data also changes it. A static address needs a request to your provider.
How do I find my private IP address on Windows, Mac or a phone?
On Windows run ipconfig in Command Prompt. On macOS open System Settings, Network and choose your connection. On a phone open the Wi-Fi settings and tap your network. The private address differs from the public one shown on this page.
Is my IP address static or dynamic?
Most home connections have a dynamic address that can change when your router restarts or your provider reassigns it. Businesses often pay for a static address that does not change.
Does this page store my IP address?
No. The address is shown to you and is not saved in your browser or on this page.
