What Is My IP
Find your public IP address instantly
What Is My IP is a free online tool that instantly detects and displays your device's public IP address, with no sign-up required. It reads the IP address your internet connection presents to the websites you visit, showing you exactly what other services see. Network troubleshooters, remote workers, and anyone checking their connection details use it to quickly confirm their current public IP.
What is a Public IP Address?
A public IP address is the unique numeric identifier your internet service provider assigns to your connection so it can communicate with the wider internet. It differs from your private IP address, which only identifies your device within your home or office network. Websites, servers, and online services use your public IP to route data back to you and, in many cases, to estimate your general location.

Frequently asked questions
Is What Is My IP free to use?
Yes, the tool is completely free and requires no sign-up to check your public IP address. You can use it as many times as you need across different devices and networks.
Why does my IP address change sometimes?
Most home internet connections use dynamic IP addresses that your provider periodically reassigns, especially after restarting your router or reconnecting. Business or hosting connections often use a static IP that stays the same unless deliberately changed.
Does this tool show my exact location?
No, the tool only shows your public IP address itself and does not calculate or display precise location data. IP-based location estimates are generally accurate to a city or region level at best, not an exact street address.
What is the difference between IPv4 and IPv6?
IPv4 addresses use a shorter numeric format with four groups of digits separated by periods, while IPv6 uses a longer alphanumeric format designed to support far more unique addresses. The tool displays whichever version, or both, your current connection is using.
