What is true web speed?▾
True web speed is the average of your five fastest major CDN downloads — Google, Cloudflare, Netflix, Amazon, and others — not a single test server. It reflects how fast you reach the networks that actually deliver the web.
How accurate is SpeedIP?▾
Download is measured across real CDN endpoints in parallel. Upload uses multi-stream testing to our edge server. Latency, jitter, and bufferbloat are measured in the same run.
What is bufferbloat?▾
Bufferbloat occurs when your router's buffers are too large, causing latency spikes during heavy traffic. SpeedIP measures your ping before and during speed tests and grades bufferbloat from A (excellent) to F (severe).
Do I need to create an account?▾
No account is required. Core tools are free, and full-test history is saved on this device. See our privacy policy for details.
What is a good internet speed?▾
A practical planning target is 25 Mbps per 4K stream, with additional capacity for other devices. Calls also need upload capacity; gaming depends heavily on low latency and jitter. These are estimates, not guarantees.
