Frequently Asked Questions
An IP (Internet Protocol) address is a number that identifies your device on a network. Your internet provider assigns you a public IP, and every website you visit sees that address so it knows where to send the pages you requested. Think of it like a return address on an envelope: sites rarely know who you are, but they must know where to deliver the response.
IPv4 addresses are 32-bit numbers written as four decimal blocks, like 203.0.113.42 — about 4.3 billion possible addresses, which have effectively run out. IPv6 addresses are 128-bit numbers written as eight hexadecimal groups, like 2001:0db8:85a3::8a2e:0370:7334, providing a vastly larger space. If the badge on this page says IPv6, your provider and network support the newer protocol and your browser preferred it.
Yes. When you use a VPN, websites — and this page — see the VPN server’s IP address instead of your own. Your traffic is routed through the VPN provider, so your real address is replaced by theirs. The same applies to proxies, Tor, and many corporate networks. Note that DNS leaks or WebRTC leaks can still expose details in some setups, and the VPN provider itself knows your real IP.
Several normal situations change the address you present. Mobile networks use CGNAT (carrier-grade NAT), so your address can change between cells or sessions. Home connections often get a dynamic IP that rotates on reconnection or lease renewal. If you switch between Wi-Fi and cellular, use a VPN on one device but not another, or connect over IPv6 at one moment and IPv4 the next, the reported address changes too — it is the address of your current network path, not a fixed identity.
An IP address can identify a household or connection, so privacy laws often treat it as personal data. This tool does not store it: your browser requests a small endpoint on our server, which echoes back the address and user agent it saw for that single request, with caching disabled. Nothing is written to a database, and no third-party IP service is involved.
Quick Answer
Your public IP address is shown in large type above. It is the address your internet provider assigns to your connection (or to the VPN/proxy you are using), and it is how websites route responses back to you. The badge next to it tells you whether you are connecting over IPv4 or IPv6, and the line below shows the user agent your browser sends with every request. The lookup happens in your own browser — your request goes to our server, which echoes back the address it saw, and nothing is stored or logged.
Key Facts
- Shows your public IP exactly as our server received it from your connection
- Classifies the address as IPv4 or IPv6 automatically
- Displays the user agent your browser sends with every HTTP request
- No third-party IP services are called — the address comes from our own endpoint
- Nothing is logged or stored; each lookup is a single request with no caching
- Works on desktop, tablet, and mobile with no installation or signup
Frequently Asked Questions
What is an IP address?
An IP (Internet Protocol) address is a number that identifies your device on a network. Your internet provider assigns you a public IP, and every website you visit sees that address so it knows where to send the pages you requested.

What is the difference between IPv4 and IPv6?
IPv4 addresses are 32-bit numbers written as four decimal blocks, like 203.0.113.42 — about 4.3 billion possible addresses, which have effectively run out. IPv6 addresses are 128-bit numbers written as eight hexadecimal groups, like 2001:0db8:85a3::8a2e:0370:7334, providing a vastly larger space. If the badge on this page says IPv6, your provider and network support the newer protocol and your browser preferred it.
Can a VPN hide my IP address?
Yes. When you use a VPN, websites — and this page — see the VPN server’s IP address instead of your own. Your traffic is routed through the VPN provider, so your real address is replaced by theirs. The same applies to proxies, Tor, and many corporate networks. Note that DNS leaks or WebRTC leaks can still expose details in some setups, and the VPN provider itself knows your real IP.
Why does my IP differ from what a site told me before?
Several normal situations change the address you present. Mobile networks use CGNAT (carrier-grade NAT), so your address can change between cells or sessions. Home connections often get a dynamic IP that rotates on reconnection or lease renewal. If you switch between Wi-Fi and cellular, use a VPN on one device but not another, or connect over IPv6 at one moment and IPv4 the next, the reported address changes too — it is the address of your current network path, not a fixed identity.
Is my IP address personal data, and do you store it?
An IP address can identify a household or connection, so privacy laws often treat it as personal data. This tool does not store it: your browser requests a small endpoint on our server, which echoes back the address and user agent it saw for that single request, with caching disabled. Nothing is written to a database, and no third-party IP service is involved.
