Useful applications

  • Check which public IPv4 address a website sees during network troubleshooting.
  • Verify whether connecting to a VPN or proxy changes the visible IPv4 address.
  • Confirm the address before adding it to a temporary allowlist or sharing it for remote support.

Notes and limitations

  • The public IPv4 address can differ from private addresses used by devices inside your local network.
  • A provider, router, VPN, or proxy can change the visible address, and a reverse-DNS hostname may not be configured.

Frequently asked questions

Why is this address different from my local IP address?
