  3. Use the toolbar to turn automatic refreshing on or off.

Useful applications

  • Checking a public address during network troubleshooting.
  • Verifying whether a VPN or proxy changes the visible IPv4 address.
  • Confirming an address for a temporary allowlist or remote-support task.

Notes and limitations

  • The tool shows the public address of the connection, not necessarily a device address inside the local network.
  • The address can change because of the router, provider, VPN, or proxy. This tool supports IPv4 only.
