Important notes

Are these results exact?

They are measurements between your browser and this test server, not a guaranteed measurement of every route on the internet. Run more than once for a steadier estimate.

Can it identify my 4G, 5G or Wi-Fi?

Some browsers expose an approximate connection type. Many browsers hide this information, so it may show as unavailable. The test cannot reliably detect whether a Wi-Fi connection is 2.4 GHz or 5 GHz.

Does packet loss mean my ISP has a problem?

Not necessarily. A small browser test can be affected by device load, Wi-Fi interference, background tabs and server routing. Treat packet loss as an estimate and repeat the test.

Is my IP address private?

Your public IP is sent to the speed-test server as part of normal internet communication. An optional third-party IP lookup is used to show provider and approximate region. Do not share a report publicly if you do not want to reveal your IP.
