+# Changelog
+
+## 2026-03-26 - 4.5.1 - fix(ipintelligence)
+handle flat geolocation MMDB schema and clean up DNS client lifecycle
+
+- update IP intelligence lookups to read geolocation fields from the flat @ip-location-db schema instead of MaxMind nested city records
+- destroy the Team Cymru DNS client after queries to avoid leaking resources
+- adjust IP intelligence tests to validate countryCode-based geolocation and RDAP fields against current data sources
+
+## 2026-03-26 - 4.5.0 - feat(smartnetwork)
+add Rust-powered network diagnostics bridge and IP intelligence lookups
+
+- replace system-dependent ping, traceroute, port checks, and gateway detection with a Rust IPC binary integrated through smartrust
+- add IP intelligence support combining RDAP, ASN, and MaxMind geolocation data
+- update build configuration to compile and package Rust binaries for Linux amd64 and arm64
+- refresh tests and docs for explicit SmartNetwork start/stop lifecycle and new functionality
+
+## 2025-09-12 - 4.4.0 - feat(smartnetwork)
+Add exclude option to findFreePort and skip excluded ports during search
+
+- Add an 'exclude' array to IFindFreePortOptions so callers can specify ports to ignore when searching for a free port.
+- Respect excluded ports in findFreePort for both random (randomize=true) and sequential searches so excluded ports are never returned.
+- Add .claude/settings.local.json to include local permissions used for development/CI helpers.
+
+## 2025-09-12 - 4.3.0 - feat(smartnetwork)
+Add randomizable port search and switch DNS resolution to @push.rocks/smartdns; export smartdns and update docs
+
+- findFreePort: added options.randomize (IFindFreePortOptions) to return a random available port within a range; retains default sequential search behavior
+- resolveDns: switched to @push.rocks/smartdns client with 'prefer-system' strategy and DoH fallback; now returns parsed A, AAAA and MX records
+- Exported smartdns from the internal plugins module and added @push.rocks/smartdns dependency
+- Documentation updates: readme clarifies random port selection, DNS resolution strategy and adds examples for random findFreePort usage
+- Bumped @git.zone/tstest dev dependency to ^2.3.7
+
+## 2025-09-12 - 4.2.0 - feat(PublicIp)
+Add PublicIp service and refactor SmartNetwork to use it; remove public-ip dependency; update exports, docs and dependencies
+
+- Add PublicIp class (ts/smartnetwork.classes.publicip.ts) implementing public IPv4/IPv6 lookup with multiple fallback services, timeouts and validation
+- Refactor SmartNetwork.getPublicIps to use the new PublicIp class and preserve caching behavior
+- Export PublicIp from package entry (ts/index.ts)
+- Remove public-ip from plugins/exports and stop using the public-ip package
+- Bump devDependencies and runtime dependency versions in package.json (@git.zone/tsbuild, @git.zone/tstest, @push.rocks/smartenv, systeminformation)
+- Improve README: expanded usage, examples, formatting and added emojis for clarity
+- Add project local settings file (.claude/settings.local.json) for CI/permissions configuration
+
+## 2025-07-31 - 4.1.0 - feat(port-management)
+Add findFreePort method for automatic port discovery within a range
+
+- Added new `findFreePort` method to SmartNetwork class that finds the first available port in a specified range
+- Added comprehensive tests for the new port finding functionality
+- Updated README documentation with usage examples for the new feature
+- Improved port management capabilities for dynamic port allocation scenarios
+
+## 2025-05-19 - 4.0.2 - fix(tests)
+Update dev dependencies and refactor test assertions for improved clarity
+
+- Bumped @git.zone/tsbuild version to ^2.5.1
+- Bumped @git.zone/tstest version to ^1.9.0
+- Updated npm test script to include the verbose flag
+- Replaced expectAsync assertions with resolves based assertions in test files
+
+## 2025-05-03 - 4.0.1 - fix(formatting)

+Enhance documentation and add configurable speed test options with plugin architecture improvements
+
+- Expanded README with detailed examples for traceroute, speed test, ping, and remote port checks
+- Added optional parameters for getSpeed (parallelStreams and duration) to allow configurable testing modes
+- Included plugin architecture usage examples to show runtime registration and unregistration of plugins
+- Updated test suite to cover DNS resolution, endpoint health-check, caching behavior, and various network diagnostics
+- Removed legacy planning documentation from readme.plan.md
+
+## 2025-04-28 - 3.0.5 - fix(core)
+Improve logging and error handling by introducing custom error classes and a global logging interface while refactoring network diagnostics methods.
+
+- Added custom error classes (NetworkError, TimeoutError) for network operations.
+- Introduced a global logging interface to replace direct console logging.
+- Updated CloudflareSpeed and SmartNetwork classes to use getLogger for improved error reporting.
+- Disabled connection pooling in HTTP requests to prevent listener accumulation.
+
+## 2025-04-28 - 3.0.4 - fix(ci/config)
+Improve CI workflows, update project configuration, and clean up code formatting

+# 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

+## 💻 Usage
+
+### Basic Setup
+
+First, import and initialize SmartNetwork:

 ```typescript
-import * as smartnetwork from 'smartnetwork';
-const testSmartNetwork = new smartnetwork.SmartNetwork();
-const run = async () => {
-  // measure average speed over a period of 5 seconds
-  // the structure of speedResult is self explanatory using TypeScript (or the linked TypeDoc above)
-  const speedResult: smartnetwork.SpeedResult = testSmartNetwork.getSpeed(5000);
+import { SmartNetwork } from '@push.rocks/smartnetwork';

-  // you can check for local ports before trying to bind to it from your nodejs program
-  const isLocalPortUnused: boolean = await testSmartNetwork.isLocalPortUnused(1234);
+// Basic instance
+const network = new SmartNetwork();

-  // you can run basic port checks on remote domains.
-  const isRemotePortAvailable: boolean = await testSmartNetwork.isRemotePortAvailable(
-    'google.com:80'
-  );
+// Start the Rust bridge (auto-started on first use, but explicit start is recommended)
+await network.start();

-  // just another way to call for the same thing as above
-  const isRemotePortAvailable: boolean = await testSmartNetwork.isRemotePortAvailable(
-    'google.com',
-    80
-  );
+// ... use the network instance ...
+
+// Clean up when done (stops the Rust bridge process)
+await network.stop();
+
+// With caching enabled (60 seconds TTL)
+const cachedNetwork = new SmartNetwork({ cacheTtl: 60000 });
+```
+
+### 🏎️ Network Speed Testing
+
+Measure your network performance using Cloudflare's global infrastructure:
+
+```typescript
+const speedTest = async () => {
+  // Quick speed test
+  const result = await network.getSpeed();
+  console.log(`Download: ${result.downloadSpeed} Mbps`);
+  console.log(`Upload: ${result.uploadSpeed} Mbps`);
+
+  // Advanced configuration
+  const advancedResult = await network.getSpeed({ 
+    parallelStreams: 3,  // Number of concurrent connections
+    duration: 5          // Test duration in seconds
+  });
+  console.log(`Download: ${advancedResult.downloadSpeed} Mbps`);
+  console.log(`Upload: ${advancedResult.uploadSpeed} Mbps`);
 };
 ```

+```typescript
+const checkLocalPort = async (port: number) => {
+  const isUnused = await network.isLocalPortUnused(port);
+  if (isUnused) {
+    console.log(`✅ Port ${port} is available`);
+  } else {
+    console.log(`❌ Port ${port} is in use`);
+  }
+};

-[![repo-footer](https://lossless.gitlab.io/publicrelations/repofooter.svg)](https://maintainedby.lossless.com)
+await checkLocalPort(8080);
+```
+
+#### Find Free Port in Range
+
+Automatically discover available ports:
+
+```typescript
+const findFreePort = async () => {
+  // Find a free port between 3000 and 3100 (sequential - returns first available)
+  const freePort = await network.findFreePort(3000, 3100);
+  
+  if (freePort) {
+    console.log(`🎉 Found free port: ${freePort}`);
+  } else {
+    console.log('😢 No free ports available in range');
+  }
+  
+  // Find a random free port in range (useful to avoid port conflicts)
+  const randomPort = await network.findFreePort(3000, 3100, { randomize: true });
+  console.log(`🎲 Random free port: ${randomPort}`);
+  
+  // Exclude specific ports from the search
+  const portWithExclusions = await network.findFreePort(3000, 3100, {
+    exclude: [3000, 3001, 3005]  // Skip these ports even if they're free
+  });
+  console.log(`🚫 Free port (excluding specific ports): ${portWithExclusions}`);
+  
+  // Combine randomize with exclude options
+  const randomWithExclusions = await network.findFreePort(3000, 3100, {
+    randomize: true,
+    exclude: [3000, 3001, 3005]
+  });
+  console.log(`🎲🚫 Random free port (with exclusions): ${randomWithExclusions}`);
+};
+```
+
+#### Check Remote Port Availability
+
+Test if services are accessible on remote servers:
+
+```typescript
+// Method 1: Using "host:port" syntax
+const isOpen1 = await network.isRemotePortAvailable('example.com:443');
+
+// Method 2: Using separate host and port
+const isOpen2 = await network.isRemotePortAvailable('example.com', 443);
+
+// Method 3: With advanced options
+const isOpen3 = await network.isRemotePortAvailable('example.com', {
+  port: 443,
+  protocol: 'tcp',     // Only TCP is supported
+  retries: 3,          // Number of connection attempts
+  timeout: 5000        // Timeout per attempt in ms
+});
+
+// Note: UDP is not supported
+try {
+  await network.isRemotePortAvailable('example.com', { 
+    port: 53, 
+    protocol: 'udp' 
+  });
+} catch (e) {
+  console.error('UDP not supported:', e.code); // ENOTSUP
+}
+```
+
+### 📡 Network Connectivity
+
+#### Ping Operations
+
+Test connectivity and measure latency:
+
+```typescript
+// Simple ping
+const pingResult = await network.ping('google.com');
+console.log(`Host alive: ${pingResult.alive}`);
+console.log(`RTT: ${pingResult.time} ms`);
+
+// Detailed ping statistics
+const pingStats = await network.ping('google.com', { 
+  count: 5,          // Number of pings
+  timeout: 1000      // Timeout per ping in ms
+});
+
+console.log(`📊 Ping Statistics:`);
+console.log(`  Packet loss: ${pingStats.packetLoss}%`);
+console.log(`  Min: ${pingStats.min} ms`);
+console.log(`  Max: ${pingStats.max} ms`);
+console.log(`  Avg: ${pingStats.avg.toFixed(2)} ms`);
+console.log(`  Stddev: ${pingStats.stddev.toFixed(2)} ms`);
+```
+
+#### Traceroute
+
+Analyze network paths hop-by-hop:
+
+```typescript
+const hops = await network.traceroute('google.com', { 
+  maxHops: 10,      // Maximum number of hops
+  timeout: 5000     // Timeout in ms
+});
+
+console.log('🛤️ Route to destination:');
+hops.forEach(hop => {
+  const rtt = hop.rtt === null ? '*' : `${hop.rtt} ms`;
+  console.log(`  ${hop.ttl}\t${hop.ip}\t${rtt}`);
+});
+```
+
+*Note: Falls back to a single-hop stub if the `traceroute` binary is unavailable.*
+
+### 🌍 DNS Operations
+
+Resolve various DNS record types using @push.rocks/smartdns with intelligent resolution strategy:
+
+```typescript
+const dnsRecords = await network.resolveDns('example.com');
+
+console.log('🔍 DNS Records:');
+console.log('  A records:', dnsRecords.A);        // IPv4 addresses
+console.log('  AAAA records:', dnsRecords.AAAA);  // IPv6 addresses
+
+// MX records include priority
+dnsRecords.MX.forEach(mx => {
+  console.log(`  📧 Mail server: ${mx.exchange} (priority: ${mx.priority})`);
+});
+
+// Properly handles local hostnames (localhost, etc.)
+const localDns = await network.resolveDns('localhost');
+console.log('  Localhost:', localDns.A);  // Returns ['127.0.0.1']
+```
+
+*DNS resolution uses a `prefer-system` strategy: tries system resolver first (respects /etc/hosts and local DNS), with automatic fallback to Cloudflare DoH for external domains.*
+
+### 🏥 HTTP/HTTPS Health Checks
+
+Monitor endpoint availability and response times:
+
+```typescript
+const health = await network.checkEndpoint('https://api.example.com/health', {
+  timeout: 5000  // Request timeout in ms
+});
+
+console.log(`🩺 Endpoint Health:`);
+console.log(`  Status: ${health.status}`);
+console.log(`  RTT: ${health.rtt} ms`);
+console.log(`  Headers:`, health.headers);
+```
+
+### 🖥️ Network Interface Information
+
+#### Get All Network Interfaces
+
+List all network adapters on the system:
+
+```typescript
+const gateways = await network.getGateways();
+
+Object.entries(gateways).forEach(([name, interfaces]) => {
+  console.log(`🔌 Interface: ${name}`);
+  interfaces.forEach(iface => {
+    console.log(`  ${iface.family}: ${iface.address}`);
+    console.log(`  Netmask: ${iface.netmask}`);
+    console.log(`  MAC: ${iface.mac}`);
+  });
+});
+```
+
+#### Get Default Gateway
+
+Retrieve the primary network interface:
+
+```typescript
+const defaultGateway = await network.getDefaultGateway();
+
+if (defaultGateway) {
+  console.log('🌐 Default Gateway:');
+  console.log('  IPv4:', defaultGateway.ipv4.address);
+  console.log('  IPv6:', defaultGateway.ipv6.address);
+}
+```
+
+### 🌎 Public IP Discovery
+
+Discover your public-facing IP addresses:
+
+```typescript
+const publicIps = await network.getPublicIps();
+
+console.log(`🌍 Public IPs:`);
+console.log(`  IPv4: ${publicIps.v4 || 'Not available'}`);
+console.log(`  IPv6: ${publicIps.v6 || 'Not available'}`);
+```
+
+### ⚡ Performance Caching
+
+Reduce network calls with built-in caching:
+
+```typescript
+// Create instance with 60-second cache TTL
+const cachedNetwork = new SmartNetwork({ cacheTtl: 60000 });
+
+// First call fetches from network
+const gateways1 = await cachedNetwork.getGateways();
+const publicIps1 = await cachedNetwork.getPublicIps();
+
+// Subsequent calls within 60 seconds use cache
+const gateways2 = await cachedNetwork.getGateways();    // From cache ⚡
+const publicIps2 = await cachedNetwork.getPublicIps();  // From cache ⚡
+```
+
+### 🔧 Plugin Architecture
+
+Extend SmartNetwork with custom functionality:
+
+```typescript
+// Define your plugin
+class CustomNetworkPlugin {
+  constructor(private smartNetwork: SmartNetwork) {}
+  
+  async customMethod() {
+    // Your custom network logic here
+    return 'Custom result';
+  }
+}
+
+// Register the plugin
+SmartNetwork.registerPlugin('customPlugin', CustomNetworkPlugin);
+
+// Use the plugin
+const network = new SmartNetwork();
+const PluginClass = SmartNetwork.pluginsRegistry.get('customPlugin');
+const plugin = new PluginClass(network);
+await plugin.customMethod();
+
+// Clean up when done
+SmartNetwork.unregisterPlugin('customPlugin');
+```
+
+### 🚨 Error Handling
+
+Handle network errors gracefully with custom error types:
+
+```typescript
+import { NetworkError } from '@push.rocks/smartnetwork';
+
+try {
+  await network.isRemotePortAvailable('example.com', { protocol: 'udp' });
+} catch (error) {
+  if (error instanceof NetworkError) {
+    console.error(`❌ Network error: ${error.message}`);
+    console.error(`   Error code: ${error.code}`);
+  }
+}
+```
+
+### 📚 TypeScript Support
+
+This package is written in TypeScript and provides comprehensive type definitions:
+
+```typescript
+interface SmartNetworkOptions {
+  cacheTtl?: number;  // Cache TTL in milliseconds
+}
+
+interface IFindFreePortOptions {
+  randomize?: boolean;  // If true, returns a random free port instead of the first one
+  exclude?: number[];   // Array of port numbers to exclude from the search
+}
+
+interface Hop {
+  ttl: number;        // Time to live
+  ip: string;         // IP address of the hop
+  rtt: number | null; // Round trip time in ms
+}
+
+// ... and many more types for complete type safety
+```
+
+## 🛠️ Advanced Examples
+
+### Building a Network Monitor
+
+```typescript
+const monitorNetwork = async () => {
+  const network = new SmartNetwork({ cacheTtl: 30000 });
+  
+  // Check critical services
+  const services = [
+    { name: 'Web Server', host: 'example.com', port: 443 },
+    { name: 'Database', host: 'db.internal', port: 5432 },
+    { name: 'Cache', host: 'redis.internal', port: 6379 }
+  ];
+  
+  for (const service of services) {
+    const isUp = await network.isRemotePortAvailable(service.host, service.port);
+    console.log(`${service.name}: ${isUp ? '✅ UP' : '❌ DOWN'}`);
+  }
+  
+  // Check internet connectivity
+  const ping = await network.ping('8.8.8.8');
+  console.log(`Internet: ${ping.alive ? '✅ Connected' : '❌ Disconnected'}`);
+  
+  // Measure network performance
+  const speed = await network.getSpeed();
+  console.log(`Speed: ⬇️ ${speed.downloadSpeed} Mbps / ⬆️ ${speed.uploadSpeed} Mbps`);
+};
+
+// Run monitor every minute
+setInterval(monitorNetwork, 60000);
+```
+
+### Service Discovery
+
+```typescript
+const discoverServices = async () => {
+  const network = new SmartNetwork();
+  const commonPorts = [22, 80, 443, 3000, 3306, 5432, 6379, 8080, 9200];
+  
+  console.log('🔍 Scanning local services...');
+  
+  for (const port of commonPorts) {
+    const isUsed = !(await network.isLocalPortUnused(port));
+    if (isUsed) {
+      console.log(`  Port ${port}: In use (possible service running)`);
+    }
+  }
+};
+```
