IP Detection
Your IP address is your unique identifier on the internet. See your public IP, ISP, and network details below.
Your IP address is a unique number assigned by your Internet Service Provider (ISP) that identifies your device on the internet. It reveals your approximate location and ISP. Every website you visit can see it.
Every device connected to the internet has an IP address. This unique identifier allows websites and services to send data back to your device. Your IP address also reveals your approximate geographic location and your Internet Service Provider (ISP).
Most residential users have a dynamic IP address that may change periodically. If you need a consistent IP for hosting services or remote access, you may need to request a static IP from your ISP.
The diagnostics panel above tests both address families independently. If IPv6 came back as supported, your ISP has deployed dual-stack networking: your device holds a globally routable IPv6 address of its own, and traffic to IPv6-capable services (Google, Cloudflare, Netflix, most major CDNs) travels end to end without translation. That generally means lower latency on the first connection, no shared-address side effects, and inbound connections that can actually reach your machine if your router firewall allows them.
If the test reported IPv4 only, your traffic almost certainly passes through Carrier-Grade NAT. Hundreds or thousands of subscribers share one public IPv4 address, and the carrier rewrites port numbers to keep the sessions apart. The practical consequences show up in specific places: port forwarding on your router silently stops working, peer-to-peer file transfer and self-hosted game servers refuse inbound connections, some sites rate-limit or CAPTCHA you because a neighbour on the same shared address triggered abuse detection, and remote-desktop tools fall back to relay servers. None of it is a fault on your side — it is an address-scarcity workaround, and the fix is asking your ISP for either a dedicated IPv4 address or IPv6 enablement.
Notation differs between the two: IPv4 is four decimal octets separated by dots, capped at roughly 4.3 billion unique addresses worldwide. IPv6 is eight groups of four hexadecimal digits separated by colons, with consecutive zero groups collapsed to a double colon. The pool is 340 undecillion addresses, which is why the protocol hands out whole prefixes rather than single addresses.
A VPN is doing its job when the public IP shown at the top of this page belongs to the VPN provider rather than your home ISP, and when the country matches the exit server you selected. The diagnostics panel adds a second, sharper check: it compares the timezone your browser reports against the timezone derived from your public IP. A mismatch is expected and healthy while a VPN is on — it confirms your apparent location has moved. A perfect match while you believe a VPN is active usually means the tunnel dropped, split tunnelling excluded your browser, or the provider's exit node happens to sit in your own country.
Two leaks defeat an otherwise working tunnel. DNS leaks send your lookups to your ISP's resolver even while traffic is encrypted, which hands your browsing history to exactly the party you were hiding it from. WebRTC leaks let a page enumerate your local and public addresses through the peer-connection API, bypassing the tunnel entirely. Neither is visible in a plain IP lookup, so treat this page as the first check rather than the only one.
Worth being precise about what an IP does and does not expose. It does not reveal your name, your street address, your device, your browsing history, or anything stored on your computer. What it reveals is the network you connected through and an estimate of where that network terminates — which for mobile carriers and large ISPs is regularly a regional aggregation point tens or hundreds of kilometres from where you are sitting. Only your ISP can map the address back to a subscriber account, and in most jurisdictions that requires a legal order.
Need to find your public network address? This free lookup tool instantly reveals the numerical identifier that websites and online services see when you connect. Whether troubleshooting connectivity, configuring remote access, or verifying VPN status, knowing your external address is the essential first step.
Every internet-connected device receives a unique identifier for routing data. The public version—visible to websites—differs from private addresses used within home or office networks. Understanding this distinction helps when setting up routers, firewalls, or diagnosing why certain services cannot reach your device.
Two address formats exist: IPv4 uses 32-bit notation (e.g., 192.168.1.1) with roughly 4.3 billion possibilities, while IPv6 uses 128-bit addresses for virtually unlimited capacity. Our detection automatically identifies which format your connection uses and displays relevant details.
Geographic data derived from your address typically includes ISP name, approximate city or region, and timezone—but never your exact street location. For enhanced privacy, VPN services route traffic through remote servers, masking your actual origin from destination websites.
Common scenarios requiring address verification: confirming VPN tunnels function correctly, troubleshooting port forwarding for gaming or self-hosted services, testing access to geo-restricted content, and providing accurate details to technical support teams. No files or system settings are accessed—detection happens entirely through your browser connection.

An IP (Internet Protocol) address is a unique numerical label assigned to every device connected to a computer network. It serves two main purposes: identifying the host or network interface and providing the location of the device in the network.
IPv4 uses 32-bit addresses (like 192.168.1.1) allowing about 4.3 billion unique addresses. IPv6 uses 128-bit addresses (like 2001:0db8:85a3:0000:0000:8a2e:0370:7334) providing virtually unlimited addresses to accommodate the growing number of internet-connected devices.
Your IP address reveals your approximate geographic location (city/region level) and your Internet Service Provider. While it can't pinpoint your exact address, it can be used in combination with other data. Using a VPN can help mask your real IP address.
Most home internet connections use dynamic IP addresses assigned by your ISP. These can change when you restart your router or periodically by your ISP. Businesses often use static IP addresses that remain constant.
