Public IP Address Check
Useful when checking whether a VPN, proxy or network change affected the address websites see.

Ready
DeviceOK measures browser-visible connection hints and HTTP round trips to DeviceOK. Throughput samples use small HTTP transfers to DeviceOK and are useful for quick comparison, not ISP speed certification. This is not an ICMP ping, local-network scan, or VoIP/RTP jitter measurement. A public IP can represent a VPN, carrier gateway, proxy, or shared NAT rather than a physical device address.
Private by design
DeviceOK returns the network address already visible to the web request; it does not scan your LAN.
Use the result as evidence, not a guess.

The result may be a VPN, carrier gateway, proxy or shared NAT address.
It is not a precise physical-location identifier.
