+# Project Analysis
+
+## Architecture Overview
+This is a comprehensive network diagnostics toolkit. The main entry point is the `SmartNetwork` class which orchestrates all functionality. System-dependent operations are delegated to a Rust binary via JSON-over-stdin/stdout IPC using `@push.rocks/smartrust`.
+
+Key features:
+- Speed testing via Cloudflare (parallelizable with duration support) — pure TS
+- ICMP ping with statistics — Rust binary (surge-ping)
+- Port availability checks (local and remote) — Rust binary (tokio TCP / socket2)
+- Network gateway discovery — Rust binary (parses /proc/net/route on Linux)
+- Public IP retrieval — pure TS
+- DNS resolution via smartdns — pure TS
+- HTTP endpoint health checks — pure TS
+- Traceroute — Rust binary (raw ICMP sockets via socket2)
+
+## Rust Binary Architecture (v4.5.0+)
+
+### Binary: `rustnetwork`
+- Located in `rust/crates/rustnetwork/`
+- Cross-compiled for linux_amd64 and linux_arm64 via `@git.zone/tsrust`
+- Output: `dist_rust/rustnetwork_linux_amd64`, `dist_rust/rustnetwork_linux_arm64`
+- IPC mode: `--management` flag for JSON-over-stdin/stdout
+
+### IPC Commands
+| Method | Description |
+|--------|-------------|
+| `healthPing` | Liveness check (returns `{ pong: true }`) |
+| `ping` | ICMP ping with count/timeout, returns stats |
+| `traceroute` | Hop-by-hop latency via raw ICMP sockets |
+| `tcpPortCheck` | TCP connect probe to remote host:port |
+| `isLocalPortFree` | Bind test on IPv4 + IPv6 |
+| `defaultGateway` | Parse /proc/net/route for default interface |
+
+### TypeScript Bridge
+- `ts/smartnetwork.classes.rustbridge.ts` — Singleton `RustNetworkBridge` wrapping `smartrust.RustBridge`
+- `SmartNetwork` class has `start()`/`stop()` lifecycle for the bridge
+- `ensureBridge()` auto-starts on first use
+
+### Build Pipeline
+- `pnpm build` = `tsbuild tsfolders --allowimplicitany && tsrust`
+- Targets configured in `.smartconfig.json` under `@git.zone/tsrust`
+
+## Key Components
+
+### SmartNetwork Class
+- Central orchestrator for all network operations
+- Requires `start()` before using ping/traceroute/port/gateway operations
+- Supports caching via `cacheTtl` option for gateway and public IP lookups
+- Plugin architecture for extensibility
+
+### RustNetworkBridge Class
+- Singleton pattern via `getInstance()`
+- Binary search: dist_rust/ (platform-suffixed) > rust/target/release/ > rust/target/debug/
+- `searchSystemPath: false` — only looks in local paths
+
+### CloudflareSpeed Class
+- Handles internet speed testing using Cloudflare's infrastructure
+- Supports parallel streams and customizable test duration
+- Upload speed measurement uses server-timing header with client-side timing fallback
+
+### Error Handling
+- Custom `NetworkError` and `TimeoutError` classes for better error context
+- Error codes follow Node.js conventions (ENOTSUP, EINVAL, ETIMEOUT)
+- Ping/port methods gracefully degrade on errors (return alive=false / false)
+
+### Logging
+- Global logger interface for consistent logging across the codebase
+- Replaceable logger implementation (defaults to console)
+
+### Statistics Helpers
+- Utility functions for statistical calculations (average, median, quartile, jitter)
+- Used by speed testing; ping statistics now computed server-side in Rust
+
+## Dependencies
+- **Runtime**: `@push.rocks/smartrust` (IPC bridge), `@push.rocks/smartdns` (DNS resolution)
+- **Removed in v4.5.0**: `@push.rocks/smartping`, `@push.rocks/smartstring`, `isopen`, `systeminformation`
+- **Dev**: `@git.zone/tsrust` (Rust cross-compilation)
+
+## Testing
+- `test/test.ts` — Core smoke tests (speed, ports, gateways, public IPs)
+- `test/test.ping.ts` — ICMP ping tests (requires CAP_NET_RAW for alive=true)
+- `test/test.ports.ts` — Comprehensive port testing (27 tests)
+- `test/test.features.ts` — DNS, HTTP health check, traceroute, multi-ping, plugins, caching
+- All tests require `start()`/`stop()` lifecycle for the Rust bridge
+
+## Technical Details
+- ESM-only package (module type)
+- TypeScript with strict typing
+- Node built-in imports use `node:` prefix throughout
+- Uses native Node.js modules for HTTP/HTTPS and os.networkInterfaces()
+- Rust binary requires no elevated privileges for port checks; ICMP ping needs CAP_NET_RAW or appropriate ping_group_range
+
+## Design Patterns
+- Singleton pattern for RustNetworkBridge
+- Factory pattern for plugin registration
+- Caching pattern with TTL for expensive operations
+- Promise-based async/await throughout
+- Error propagation with custom error types
+- Graceful degradation when ICMP permissions unavailable

+Comprehensive network diagnostics and IP intelligence for Node.js — speed tests, port scanning, ICMP ping, traceroute, DNS, RDAP, ASN lookups, and geolocation in a single, promise-based toolkit.

-## Install
+## Issue Reporting and Security

-To install `@push.rocks/smartnetwork`, run the following command in your terminal:
+For reporting bugs, issues, or security vulnerabilities, please visit [community.foss.global/](https://community.foss.global/). This is the central community hub for all issue reporting. Developers who sign and comply with our contribution agreement and go through identification can also get a [code.foss.global/](https://code.foss.global/) account to submit Pull Requests directly.
+
+## 🚀 Install

 ```bash
-npm install @push.rocks/smartnetwork --save
+pnpm install @push.rocks/smartnetwork --save
 ```

-### Performing a Traceroute
+## 🎯 Overview

-You can perform a hop-by-hop traceroute to measure latency per hop. Falls back to a single-hop stub if the `traceroute` binary is unavailable.
+**@push.rocks/smartnetwork** is your Swiss Army knife for network diagnostics in Node.js. Whether you're building monitoring dashboards, investigating IP ownership, or debugging connectivity — this library has you covered with a clean, async API and zero-config setup.

-```typescript
-const hops = await myNetwork.traceroute('google.com', { maxHops: 10, timeout: 5000 });
-hops.forEach(h =>
-  console.log(`${h.ttl}\t${h.ip}\t${h.rtt === null ? '*' : h.rtt + ' ms'}`),
-);
-```
+Under the hood, system-level operations (ICMP ping, traceroute, raw-socket port checks, gateway detection) are powered by a bundled **Rust binary** for maximum performance and cross-platform reliability. Everything else — speed tests, DNS, public IP discovery, IP intelligence, HTTP health checks — runs in pure TypeScript.

-This command will download `@push.rocks/smartnetwork` and add it to your project's `package.json` file.

-In this section, we will dive deep into the capabilities of the `@push.rocks/smartnetwork` package, exploring its various features through TypeScript examples. The package is designed to simplify network diagnostics tasks, including speed tests, port availability checks, ping operations, and more.
+## 💻 Usage

 ### Basic Setup

-First, import the package into your project:
-
 ```typescript
 import { SmartNetwork } from '@push.rocks/smartnetwork';
+
+const network = new SmartNetwork();
+
+// Start the Rust bridge (auto-started on first use, but explicit start is recommended)
+await network.start();
+
+// ... use the network instance ...
+
+// Clean up when done
+await network.stop();
 ```

-Then, create an instance of `SmartNetwork`:
+Enable caching for repeated lookups:

 ```typescript
-const myNetwork = new SmartNetwork();
+const network = new SmartNetwork({ cacheTtl: 60000 }); // 60s TTL
 ```

-### Performing a Speed Test
+---

-You can measure the network speed using the `getSpeed` method. It supports optional parameters:
- `parallelStreams`: number of concurrent streams (default: 1)
- `duration`: test duration in seconds (default: fixed segments)
+### 🕵️ IP Intelligence
+
+Get ASN, organization, geolocation, and RDAP registration data for any IPv4 address. Combines three free public data sources in parallel:
+
+- **RDAP** — direct queries to RIRs (RIPE, ARIN, APNIC, LACNIC, AFRINIC) for authoritative registration data
+- **Team Cymru DNS** — fast ASN resolution via DNS TXT records
+- **MaxMind GeoLite2** — in-memory MMDB databases (auto-downloaded from CDN, periodically refreshed)

 ```typescript
-const speedTest = async () => {
-  // Default fixed-segment test
-  let r = await myNetwork.getSpeed();
-  console.log(`Download: ${r.downloadSpeed} Mbps, Upload: ${r.uploadSpeed} Mbps`);
+const intel = await network.getIpIntelligence('8.8.8.8');

-  // Parallel + duration-based test
-  r = await myNetwork.getSpeed({ parallelStreams: 3, duration: 5 });
-  console.log(`Download: ${r.downloadSpeed} Mbps, Upload: ${r.uploadSpeed} Mbps`);
-};
-
-speedTest();
+console.log(intel);
+// {
+//   asn: 15169,
+//   asnOrg: 'Google LLC',
+//   registrantOrg: 'Google LLC',
+//   registrantCountry: 'United States',
+//   networkRange: '8.8.8.0/24',
+//   abuseContact: null,
+//   country: null,
+//   countryCode: 'US',
+//   city: null,
+//   latitude: 37.751,
+//   longitude: -97.822,
+//   accuracyRadius: null,
+//   timezone: 'America/Chicago'
+// }
 ```

-### Checking Port Availability Locally
-
-The `isLocalPortUnused` method allows you to check if a specific port on your local machine is available for use.
+Works great for your own IP too:

 ```typescript
-const checkLocalPort = async (port: number) => {
-  const isUnused = await myNetwork.isLocalPortUnused(port);
-  if (isUnused) {
-    console.log(`Port ${port} is available.`);
-  } else {
-    console.log(`Port ${port} is in use.`);
-  }
-};
-
-checkLocalPort(8080); // Example port number
+const publicIps = await network.getPublicIps();
+if (publicIps.v4) {
+  const myIntel = await network.getIpIntelligence(publicIps.v4);
+  console.log(`You're on AS${myIntel.asn} (${myIntel.asnOrg}) in ${myIntel.city}, ${myIntel.countryCode}`);
+}
 ```

-### Checking Remote Port Availability
-
-To verify if a port is available on a remote server, use `isRemotePortAvailable`. You can specify target as `"host:port"` or host plus a numeric port.
+The `IIpIntelligenceResult` interface:

 ```typescript
-// Using "host:port"
-await myNetwork.isRemotePortAvailable('example.com:443');
+interface IIpIntelligenceResult {
+  // ASN (Team Cymru primary, MaxMind fallback)
+  asn: number | null;
+  asnOrg: string | null;

-// Using host + port
-await myNetwork.isRemotePortAvailable('example.com', 443);
+  // Registration (RDAP)
+  registrantOrg: string | null;
+  registrantCountry: string | null;
+  networkRange: string | null;       // CIDR or range
+  abuseContact: string | null;       // abuse email from RDAP
+
+  // Geolocation (MaxMind GeoLite2)
+  country: string | null;
+  countryCode: string | null;        // ISO 3166-1 alpha-2
+  city: string | null;
+  latitude: number | null;
+  longitude: number | null;
+  accuracyRadius: number | null;     // km
+  timezone: string | null;           // IANA timezone
+}
+```
+
+> 💡 The GeoLite2 databases are fetched into memory from jsDelivr CDN on first use (~32 MB total). They auto-refresh in the background every 7 days (configurable via `IpIntelligence` options). No disk I/O, no API keys, no rate limits.
+
+---
+
+### 🏎️ Speed Testing
+
+Measure network performance via Cloudflare's global infrastructure:
+
+```typescript
+const result = await network.getSpeed();
+console.log(`⬇️  Download: ${result.downloadSpeed} Mbps`);
+console.log(`⬆️  Upload: ${result.uploadSpeed} Mbps`);
+
+// Advanced: parallel streams + fixed duration
+const advanced = await network.getSpeed({
+  parallelStreams: 3,
+  duration: 5,
+});
+```
+
+---
+
+### 🔌 Port Management
+
+#### Check Local Port Availability
+
+Checks both IPv4 and IPv6:
+
+```typescript
+const isUnused = await network.isLocalPortUnused(8080);
+console.log(isUnused ? '✅ Port 8080 is free' : '❌ Port 8080 is in use');
+```
+
+#### Find Free Port in Range
+
+```typescript
+// First available
+const port = await network.findFreePort(3000, 3100);
+
+// Random pick (avoids clustering)
+const randomPort = await network.findFreePort(3000, 3100, { randomize: true });
+
+// With exclusions
+const port2 = await network.findFreePort(3000, 3100, {
+  randomize: true,
+  exclude: [3000, 3001, 3005],
+});
+```
+
+#### Check Remote Port
+
+```typescript
+// Simple
+const isOpen = await network.isRemotePortAvailable('example.com', 443);
+
+// With retries and timeout
+const isOpen2 = await network.isRemotePortAvailable('example.com', {
+  port: 443,
+  retries: 3,
+  timeout: 5000,
+});
+```
+
+---
+
+### 📡 Ping & Traceroute
+
+```typescript
+// Simple ping
+const ping = await network.ping('google.com');
+console.log(`Alive: ${ping.alive}, RTT: ${ping.time} ms`);
+
+// Multi-ping with statistics
+const stats = await network.ping('google.com', { count: 10, timeout: 2000 });
+console.log(`📊 min=${stats.min} avg=${stats.avg.toFixed(1)} max=${stats.max} loss=${stats.packetLoss}%`);
+
+// Traceroute
+const hops = await network.traceroute('google.com', { maxHops: 20 });
+hops.forEach(hop => {
+  const rtt = hop.rtt === null ? '*' : `${hop.rtt} ms`;
+  console.log(`  ${hop.ttl}\t${hop.ip}\t${rtt}`);
+});
+```
+
+> ⚠️ ICMP ping requires `CAP_NET_RAW` or appropriate `ping_group_range` sysctl on Linux.
+
+---
+
+### 🌍 DNS Resolution
+
+Uses `@push.rocks/smartdns` with a system-first strategy and automatic DoH (DNS-over-HTTPS) fallback:
+
+```typescript
+const dns = await network.resolveDns('example.com');
+console.log('A records:', dns.A);       // ['93.184.216.34']
+console.log('AAAA records:', dns.AAAA); // ['2606:2800:220:1:248:1893:25c8:1946']
+dns.MX.forEach(mx => {
+  console.log(`📧 ${mx.exchange} (priority ${mx.priority})`);
+});
+```
+
+---
+
+### 🏥 HTTP/HTTPS Health Checks
+
+```typescript
+const health = await network.checkEndpoint('https://api.example.com/health', {
+  timeout: 5000,
+  rejectUnauthorized: true,
+});
+console.log(`Status: ${health.status}, RTT: ${health.rtt.toFixed(0)} ms`);
+```
+
+---
+
+### 🖥️ Network Interfaces & Public IPs
+
+```typescript
+// All interfaces
+const gateways = await network.getGateways();
+Object.entries(gateways).forEach(([name, ifaces]) => {
+  console.log(`🔌 ${name}:`);
+  ifaces.forEach(i => console.log(`  ${i.family}: ${i.address}`));
+});
+
+// Default gateway
+const gw = await network.getDefaultGateway();
+if (gw) {
+  console.log(`🌐 Gateway IPv4: ${gw.ipv4.address}`);
+}
+
+// Public IPs (multiple fallback services: ipify, ident.me, seeip, icanhazip)
+const publicIps = await network.getPublicIps();
+console.log(`🌍 IPv4: ${publicIps.v4 || 'N/A'}`);
+console.log(`🌍 IPv6: ${publicIps.v6 || 'N/A'}`);
+```
+
+---
+
+### ⚡ Caching
+
+Caching applies to `getGateways()`, `getPublicIps()`, and `getIpIntelligence()`:
+
+```typescript
+const network = new SmartNetwork({ cacheTtl: 60000 }); // 60s
+
+const ips1 = await network.getPublicIps();  // fetches
+const ips2 = await network.getPublicIps();  // cache hit ⚡
+```
+
+---
+
+### 🚨 Error Handling
+
+```typescript
+import { SmartNetwork, NetworkError, TimeoutError } from '@push.rocks/smartnetwork';

-// UDP is not supported:
 try {
-  await myNetwork.isRemotePortAvailable('example.com', { port: 53, protocol: 'udp' });
-} catch (e) {
-  console.error((e as any).code); // ENOTSUP
+  await network.isRemotePortAvailable('example.com', { protocol: 'udp' });
+} catch (error) {
+  if (error instanceof NetworkError) {
+    console.error(`${error.message} (code: ${error.code})`); // ENOTSUP
+  }
 }
 ```

-### Using Ping
+Error codes: `EINVAL` (invalid argument), `ENOTSUP` (not supported), `ETIMEOUT` (timeout).

-The `ping` method sends ICMP echo requests and optionally repeats them to collect statistics.
+---
+
+### 🔧 Plugin Architecture

 ```typescript
-// Single ping
-const p1 = await myNetwork.ping('google.com');
-console.log(`Alive: ${p1.alive}, RTT: ${p1.time} ms`);
-
-// Multiple pings with statistics
-const stats = await myNetwork.ping('google.com', { count: 5 });
-console.log(
-  `min=${stats.min} ms, max=${stats.max} ms, avg=${stats.avg.toFixed(2)} ms, loss=${stats.packetLoss}%`,
-);
-```
-
-### Getting Network Gateways
-
-You can also retrieve network interfaces (gateways) and determine the default gateway. Caching with TTL is supported via constructor options.
-
-```typescript
-// Create with cache TTL of 60 seconds
-const netCached = new SmartNetwork({ cacheTtl: 60000 });
-
-// List all interfaces
-const gateways = await netCached.getGateways();
-console.log(gateways);
-
-// Get default gateway
-const defaultGw = await netCached.getDefaultGateway();
-console.log(defaultGw);
-```
-
-### Discovering Public IP Addresses
-
-To find out your public IPv4 and IPv6 addresses (with caching):
-
-```typescript
-const publicIps = await netCached.getPublicIps();
-console.log(`Public IPv4: ${publicIps.v4}`);
-console.log(`Public IPv6: ${publicIps.v6}`);
-```
-
-The `@push.rocks/smartnetwork` package provides an easy-to-use, comprehensive suite of tools for network diagnostics and monitoring, encapsulating complex network operations into simple asynchronous methods. By leveraging TypeScript, developers can benefit from type checking, ensuring that they can work with clear structures and expectations.
-
-These examples offer a glimpse into the module's utility in real-world scenarios, demonstrating its versatility in handling common network tasks. Whether you're developing a network-sensitive application, diagnosing connectivity issues, or simply curious about your network performance, `@push.rocks/smartnetwork` equips you with the tools you need.
-### Plugin Architecture
-
-You can extend `SmartNetwork` with custom plugins by registering them at runtime:
-
-```typescript
-import { SmartNetwork } from '@push.rocks/smartnetwork';
-
-// Define your plugin class or constructor
-class MyCustomPlugin {
-  // plugin implementation goes here
+class MyPlugin {
+  constructor(private network: SmartNetwork) {}
+  async doStuff() { /* ... */ }
 }

-// Register and unregister your plugin by name
-SmartNetwork.registerPlugin('myPlugin', MyCustomPlugin);
-// Later, remove it if no longer needed
+SmartNetwork.registerPlugin('myPlugin', MyPlugin);
+
+const PluginClass = SmartNetwork.pluginsRegistry.get('myPlugin');
+const plugin = new PluginClass(network);
+await plugin.doStuff();
+
 SmartNetwork.unregisterPlugin('myPlugin');
 ```

-Plugins enable you to dynamically augment the core functionality without altering the library's source.
+---
+
+### 📝 Custom Logging
+
+Replace the default `console` logger:
+
+```typescript
+import { setLogger } from '@push.rocks/smartnetwork';
+
+setLogger({
+  debug: (msg) => myLogger.debug(msg),
+  info: (msg) => myLogger.info(msg),
+  warn: (msg) => myLogger.warn(msg),
+  error: (msg) => myLogger.error(msg),
+});
+```
+
+---
+
+## 🛠️ Advanced Example: Network Monitor
+
+```typescript
+const monitor = async () => {
+  const network = new SmartNetwork({ cacheTtl: 30000 });
+
+  // Check critical services
+  const services = [
+    { name: 'Web', host: 'example.com', port: 443 },
+    { name: 'DB', host: 'db.internal', port: 5432 },
+  ];
+
+  for (const svc of services) {
+    const up = await network.isRemotePortAvailable(svc.host, svc.port);
+    console.log(`${svc.name}: ${up ? '✅ UP' : '❌ DOWN'}`);
+  }
+
+  // Internet connectivity + latency
+  const ping = await network.ping('8.8.8.8');
+  console.log(`Internet: ${ping.alive ? '✅' : '❌'} (${ping.time} ms)`);
+
+  // Speed
+  const speed = await network.getSpeed();
+  console.log(`Speed: ⬇️ ${speed.downloadSpeed} / ⬆️ ${speed.uploadSpeed} Mbps`);
+
+  // Who am I?
+  const ips = await network.getPublicIps();
+  if (ips.v4) {
+    const intel = await network.getIpIntelligence(ips.v4);
+    console.log(`AS${intel.asn} (${intel.asnOrg}) — ${intel.city || intel.countryCode}`);
+  }
+
+  await network.stop();
+};
+```
