Results stay in this browser. Copy and JSON export are created locally and omit IP address, user agent and session token.
These measurements describe only the current browser path to NekoIP.
HTTPS request latency includes browser, network, and server processing. WebTransport echo RTT and its consecutive variation measure a separate round trip to NekoIP; neither describes every Internet destination.
Kernel PMTU and TCP MSS are values reported for the direct TCP connection. They do not prove a physical MTU.
Loss, reordering and confirmed application payload come only from WebTransport application probes.
Results can change with congestion, radio conditions, routing and browser scheduling. The test does not identify a VPN type.
