Public IP Test, ISP, Location & Connection Speed
This IP test shows the public address visible to websites, approximate geolocation, and Internet Service Provider (ISP), lets you run an internet speed test, review connection privacy signals, and inspect browser-visible data. It cannot read the private address assigned by your router. Everything is on one page, free, with no sign-up.
What is an IP Address?
An IP address identifies an interface or connection on a network; several devices may share one public address through NAT. There are two versions: IPv4, formatted like 192.168.1.1, and IPv6, with a longer format like 2001:db8::1. Your public IP address is what websites and online services see when you connect, and it reveals information such as your approximate location and your ISP.
Shared, Dedicated, Dynamic or Static
A shared address can represent multiple customers through carrier-grade NAT; a dedicated address is reserved for one connection or service. A dynamic address may change over time, while a static address remains fixed by agreement with the provider. One lookup cannot prove which arrangement you have: confirm it with your ISP or compare documented observations over time.
Why Check Your IP?
Checking the visible address can help verify VPN routing, identify your ISP, inspect estimated geolocation, and diagnose network issues like latency or speed. It is also useful for confirming that your connection is properly routed.
Read the guide to public and private IP addresses to find the internal address on Windows, macOS, Linux, or mobile and understand when a public IP may be shared.
Privacy & Security
The combination of system, screen, language, and time zone can contribute to an identifiable fingerprint, but this page does not measure its uniqueness. A VPN changes the address visible to the destination and shifts trust to its provider; it does not prevent other tracking by itself. The observations explain the public IP, routing, and approximate geolocation; they are not a security audit or proof of anonymity.
IPv4 and IPv6 in Practice
Most connections today run dual-stack: they use IPv4 and IPv6 at the same time, and the browser picks one or the other depending on the destination. That is why you may see a long IPv6 address on one site and a classic IPv4 on another. IPv4 ran out years ago, so many providers share a single public address among several customers through CGNAT; IPv6, with its huge space, usually assigns addresses without that sharing. If you see an IPv6 address here, your connection already supports it; if you see only IPv4, your network or the destination does not use IPv6 yet.
Why IP Location Is Not Always Accurate
IP geolocation relies on databases that map address ranges to a city or region, not on GPS. It usually gets the country right and approximates the city, but it can point to the provider's hub instead of your real location, especially with CGNAT, mobile networks, or reassigned addresses. A VPN or proxy shows the intermediary server's location, not yours. Treat the result as an estimate: it is useful for diagnostics and routing, not for pinpointing a person.

Frequently Asked Questions
- What is an IP address? Is my IP address public?
- An IP address identifies an interface or connection within a network. A public IP can represent your router or be shared by multiple customers through NAT; this tool displays the address seen by the service you connect to.
- Can someone track my location from my IP?
- An IP address can indicate an approximate location (city or region), provider, and country. By itself, it does not normally reveal a precise street address or identify a person; the provider may link it to account records when legally required.
- What is the difference between IPv4 and IPv6?
- IPv4 uses 32-bit addresses (for example, 192.168.1.1); IPv6 uses 128-bit addresses (for example, 2001:db8::1) and provides a much larger address space. A connection may use either version or both.
- How can I hide my IP address?
- A VPN, Tor, or a proxy can replace the public IP seen by a destination, but each changes who you trust and none makes you anonymous by itself. Review your threat model and the provider's policy before choosing.
- What does ISP mean?
- ISP stands for Internet Service Provider. Your provider routes the connection and may assign you a public IP or place multiple customers behind a shared address using carrier-grade NAT.
- Is this IP lookup tool free?
- Yes, our tool is 100% free. It includes IP lookup, approximate geolocation, ISP identification, speed testing, connection privacy signals, and browser-visible data, all without sign-up.
