What parameters does this network diagnostic tool inspect?

The tool evaluates navigator.onLine connectivity, Network Information API metrics (effective connection type, downlink bandwidth, RTT latency), local WebRTC RTCPeerConnection candidate interfaces, and user-agent client headers.

What does local WebRTC ICE candidate detection test?

It verifies whether your browser's WebRTC implementation is active and properly handling local ICE candidate generation and mDNS IP masking for peer-to-peer audio/video communication.

Why are network speed and latency metrics estimated?

Connection speed (downlink Mbps) and round-trip time (RTT) are reported by the browser's Network Information API based on recent HTTP request round trips rather than an active bandwidth stress test.

Does this diagnostic tool log my IP address on external servers?

No. Diagnostics are gathered entirely in client memory using native browser APIs with zero telemetry, remote logging, or tracking cookies.

What is Browser IP & Network Info?

The Browser IP & Network Diagnostic Info tool inspects your local browser network environment, connectivity status, round-trip latency (RTT in ms), effective connection type (4G/WiFi), WebRTC local ICE interface availability, and browser client characteristics. All checks execute in private client-side JavaScript with zero third-party tracking.

Designed for accuracy, speed, and privacy, this tool runs entirely on your local device with zero network latency.

How to Use the Browser IP & Network Info

1
Open the diagnostic dashboard to initiate real-time browser network interface inspection.
2
Review active Online/Offline connectivity status, network round-trip time (RTT), and estimated downlink speed.
3
Inspect local WebRTC candidate interface status, browser user-agent parameters, and device display properties.
4
Click "Copy Network Specs" to copy a sanitized diagnostic report for technical troubleshooting or network verification.

Formula & Calculation Logic

Polls client-side Network Information API and WebRTC RTCPeerConnection interfaces to assess link quality, protocol readiness, and round-trip ping latency.

Network_State = navigator.onLine | RTT = connection.rtt | Downlink = connection.downlink Mbps
