Technical Overview: How My Network & WebRTC Diagnostics Works

The Network Diagnostics tool performs on-demand, privacy-respecting client network connectivity testing, displaying your public IPv4 and native IPv6 addresses, ISP organization, WebRTC IP leak status (with RFC 8828 mDNS analysis), browser connection metrics, and multi-CDN latency benchmarks.

Runs strictly on-demand when the user clicks "Run Network Diagnostics" (no unprompted network calls on page load). Queries public IP endpoints (ipapi.co, api64.ipify.org) directly from the browser, creates an RTCPeerConnection with STUN to audit WebRTC candidate leaks, reads the browser Network Information API, and performs cache-busted fetch HEAD requests to Cloudflare, Google, AWS, and Fastly.

Practical Examples & Usage

Running Network and WebRTC IP Leak Diagnostic

Input:Run Diagnostic Test

Output:

Public IPv4: 203.0.113.42 | ISP: Cloudflare, Inc. | Location: Ashburn, VA, US | WebRTC Leak: None (VPN Secure) | CDN Latency: 18ms

Validates public routing, measures round-trip connection latency, and confirms WebRTC does not expose local or public network IPs.

Real-World Applications & Use Cases

Verifying whether your active VPN or proxy connection is leaking real public IP addresses via WebRTC.
Testing dual-stack IPv4 and IPv6 public connectivity and routing.
Measuring roundtrip latency (ping) to major global cloud providers (Cloudflare, Google, AWS, Fastly) to diagnose slow internet speeds.
Checking browser effective connection type, downlink bandwidth, and RTT estimates via the Network Information API.

How to use My Network & WebRTC Diagnostics

Click "Run Network Diagnostics" to initiate on-demand testing with zero automatic background telemetry.
Check dual-stack public routing for both IPv4 and native IPv6 availability.
Inspect WebRTC STUN candidate exposure to verify mDNS local address masking.
Review browser-native Network Information API metrics (effective type, downlink bandwidth, RTT).
Measure HTTP roundtrip latency across distributed global edge networks (Cloudflare, Google, AWS, Fastly).

Edge Cases & Limitations

•Geographic location data is derived from IP registry databases and indicates ISP routing hubs rather than physical GPS locations.
•Latency measurements represent HTTP fetch round-trip times and may differ slightly from ICMP ping commands.
•Some privacy browsers (Brave, Firefox strict privacy) intentionally mask WebRTC candidates using mDNS .local UUIDs to prevent fingerprinting.

Recommended Best Practices

•Run diagnostics before and after enabling your VPN to verify that both IPv4 and IPv6 traffic are completely encapsulated.
•Perform latency tests across multiple regional CDN endpoints to distinguish local Wi-Fi interference from ISP peering congestion.
•Disable WebRTC in browser settings if maximum anonymity is required when using commercial privacy proxies.

Privacy & Data Handling: How My Network & WebRTC Diagnostics Treats Your Inputs

Processing Runtime

Queries public IP lookup services (such as ipapi.co and ipify.org) directly from your client browser upon explicit request to display your public IPv4, IPv6, ISP name, and regional network details.

Memory & Storage

Diagnostic measurements, latency figures, and IP details are kept in volatile browser memory and are discarded when you close or reload the browser tab.

Network Transmission

Makes client-side fetch requests to public IP APIs, runs standard WebRTC STUN candidate probes, and performs lightweight HTTP latency pings against distributed CDN edge endpoints (Cloudflare, Google, AWS, Fastly) directly from your device.

Frequently Asked Questions

What is a WebRTC IP leak and what is mDNS protection?

WebRTC establishes peer-to-peer media streams, but historically leaked private LAN IPs (192.168.x.x) even over VPNs. Modern browsers implement RFC 8828 mDNS protection, replacing raw local IPs with anonymized .local hostnames to protect user privacy.

Why are IPv4 and IPv6 tested separately?

Many ISPs and home networks remain IPv4-only or operate dual-stack. Testing IPv4 and IPv6 endpoints independently reveals if your carrier supports native IPv6 connectivity or falls back to IPv4 NAT.

Is my network or IP information logged?

No. All diagnostics run directly from your browser session to public edge servers. Outlivo runs zero intermediary proxy servers and never logs your IP address, geolocation, or network benchmarks.
