Practical guidance
Compare results with router settings and VPN state. Mobile networks may change external addresses, and several devices may share one address. Server access rules need to account for whether your IP is stable.
Before using this tool
Define what you need from My IP and device information and prepare the relevant input. When diagnosing a live service, record the test time and connection conditions so you can compare results after configuration changes. Check findings against the documentation for your software.
