## What is IP Address Checker? A tool for checking how you appear from the internet side. When you open the page, it shows the global IP address your current connection is using, along with whether IPv4 and IPv6 are each reachable. You can also check network details, the request the server received, and your browser and device environment. ## How to Use Opening the page starts the lookup and shows your connection's IP address. ## Global IP The address shown is the one this site's server receives from your connection. It reflects your normal traffic route, so it also shows whether a VPN or proxy is active. An external lookup service is used when the server value is unavailable and for the IPv4/IPv6 reachability checks. ## Network Details Your ISP (ASN and organization), country, and approximate city. The location is approximate and should not be treated as an exact address. ## What the Server Sees The content of the request the server received: the User-Agent and Accept-Language headers, the HTTP protocol, and the TLS version. These show what is actually being sent, beyond what the browser side suggests. ## Browser and Device You can see the environment of the browser you are using, such as its languages, timezone, and screen size. ## Use Cases - Confirming that a VPN or proxy changed your visible IP - Checking which IP to add to an allow list - Recording the TLS version or HTTP protocol before asking about the network requirements of an internal system - Recording your environment for test reports or support requests ## Things to Keep in Mind - Your global IP is also sent to an external lookup service. To avoid sending it, block connections to that service in your network settings - City and country data are estimates based on your IP address **How was your experience?** Last updated: October 20, 2026 ### **Related Tools** - [
