Public address

VPN connection check

Save your current public IP as a baseline, change your connection and compare a second observation. Any VPN can be used.

  • Current connection may already use a VPN
  • Changed or unchanged, with context

Useful evidence. Honest limits.

One request cannot certify your device.

A public IP describes what one endpoint sees. It does not prove that every app uses your VPN, locate you precisely or establish anonymity. These tools do not test DNS, IPv6 leaks, WebRTC leaks or speed.

Each diagnostic starts after an explicit click. Cloudflare processes connection metadata for the check; results stay in the widget’s memory and request flow. Hosting security logs are separate. Main-site analytics and support chat retain their existing settings.
