!Internet Speed Test limitationsMeasured throughput is an estimate of the connection available to this browser during the test.Expand disclaimerCollapse disclaimer⌄

The result may differ from the purchased package or another speed-test service because of device capability, browser limits, Wi-Fi or mobile signal, Ethernet negotiation, background traffic, VPNs, routing, congestion and the selected test infrastructure. Use repeated wired tests where practical before reporting a fault.

Important: Do not rely on this result alone for purchasing, configuration, security, safety, compliance, contractual or fault-diagnosis decisions. Results can be incomplete, delayed, misleading or wrong. Verify important findings with the relevant provider, manufacturer documentation and an appropriate independent test or qualified professional.

Network diagnostics

Internet Speed Test for every environment.

Run controlled download, upload, and latency checks from phones, tablets, and laptops across any network connection. Progress tracks each active stage clearly while the test runs.

Public IPv4 Address

Detecting...

Detected public IP network provider
i
An ASN is the number registered to the network that announces this public IP address. VPNs and privacy relays can change the detected network.

Detecting...

If you are using a VPN, web proxy, IP-masking service, Apple iCloud Private Relay, or a similar privacy service, the public IP and detected provider may reflect that service rather than your normal network.

Avg latency

Latency is the measured round-trip response time. Lower values usually feel more responsive.

Estimated line tier

A broad estimate based on the best measured download result. Only the provider can confirm the purchased plan.

Test context

Optional labels make saved and exported results easier to identify.

Expected package speed

Enter the speeds sold with the package to calculate the percentage achieved. Leave blank if unknown.

Automatically uses the nearest available edge and sustained multi-stream transfers. Each test measures download for 10 seconds and upload for 8 seconds after a short warm-up.

Estimated data use per test

Data use varies with the measured download and upload speeds. If both directions sustain the same speed for the full test, approximate usage can be:

100 Mbps
225 MB
1 Gbps
2.25 GB
10 Gbps
22.5 GB

Actual usage is normally lower when upload speed is slower than download speed or the connection does not sustain its maximum rate.

Automatic check

Test Reliability Guard

Ready

Runs a small ping, download and upload compatibility check before the full test. Existing test duration and controls are unchanged.

Transfer mode
i
Standard mode uses streamed transfers. Compatibility mode uses a browser-friendly fallback while keeping the same measurement duration.
Not checked
Confidence
i
Confidence describes whether browser compatibility or test conditions may have influenced the measurement.
Not checked

Runs automatically before every test session.

Hosted service check

Test-server health

Ready

The hosted latency, download and upload endpoints are checked before testing.

The estimated line tier is calculated after testing from the best download result plus a typical protocol allowance. Wi-Fi, device, congestion, and the route to this server can lower the estimate; only the provider can confirm the paid package.

Live throughput

Each dial updates from measured transfer progress and holds the latest completed reading.
