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
Connection hints are read locally.
Use the result as evidence, not a guess.

How to read it
Not all browsers expose Network Information data.
These are coarse browser estimates, not a substitute for router or ISP diagnostics.
