+# smartdns - Implementation Hints
+
+## Architecture Overview
+
+The smartdns library is structured into three main modules:
+
+1. **Client Module** (`ts_client/`) - DNS client functionality
+2. **Server Module** (`ts_server/`) - DNS server implementation
+3. **Main Module** (`ts/`) - Re-exports both client and server
+
+## Client Module (Smartdns class)
+
+### Key Features:
+- DNS record queries (A, AAAA, TXT, MX, etc.)
+- Support for multiple DNS providers (Google DNS, Cloudflare)
+- DNS propagation checking with retry logic
+- DNSSEC verification support
+- Both HTTP-based (DoH) and Node.js DNS resolver fallback
+
+### Implementation Details:
+- Uses Cloudflare's DNS-over-HTTPS API as primary resolver
+- Falls back to Node.js DNS module for local resolution
+- Implements automatic retry logic with configurable intervals
+- Properly handles quoted TXT records and trailing dots in domain names
+
+### Key Methods:
+- `getRecordsA()`, `getRecordsAAAA()`, `getRecordsTxt()` - Type-specific queries
+- `getRecords()` - Generic record query with retry support
+- `checkUntilAvailable()` - DNS propagation verification
+- `getNameServers()` - NS record lookup
+- `makeNodeProcessUseDnsProvider()` - Configure system DNS resolver
+
+## Server Module (DnsServer class)
+
+### Key Features:
+- Full DNS server supporting UDP and HTTPS (DoH) protocols
+- DNSSEC implementation with multiple algorithms
+- Dynamic handler registration for custom responses
+- Let's Encrypt integration for automatic SSL certificates
+- Wildcard domain support with pattern matching
+
+### DNSSEC Implementation:
+- Supports ECDSA (algorithm 13), ED25519 (algorithm 15), and RSA (algorithm 8)
+- Automatic DNSKEY and DS record generation
+- RRSIG signature generation for authenticated responses
+- Key tag computation following RFC 4034
+
+### Let's Encrypt Integration:
+- Automatic SSL certificate retrieval using DNS-01 challenges
+- Dynamic TXT record handler registration for ACME validation
+- Certificate renewal and HTTPS server restart capability
+- Domain authorization filtering for security
+
+### Handler System:
+- Pattern-based domain matching using minimatch
+- Support for all common record types
+- **Multiple Handler Support**: As of v7.4.2+, multiple handlers can contribute records of the same type
+- Handler chaining for complex scenarios
+- Automatic SOA response for unhandled queries
+
+### Multiple Records Support (v7.4.2+):
+- Server now processes ALL matching handlers for a query (previously stopped after first match)
+- Enables proper multi-NS record support for domain registration
+- Supports round-robin DNS with multiple A/AAAA records
+- Allows multiple TXT records (SPF, DKIM, domain verification)
+- Each handler contributes its record to the response
+
+## Key Dependencies
+
+- `dns-packet`: DNS packet encoding/decoding (wire format)
+- `elliptic`: Cryptographic operations for DNSSEC
+- `acme-client`: Let's Encrypt certificate automation
+- `minimatch`: Glob pattern matching for domains
+- `@push.rocks/smartrequest`: HTTP client for DoH queries
+- `@tsclass/tsclass`: Type definitions for DNS records
+
+## Testing Insights
+
+The test suite demonstrates:
+- Mock ACME client for testing Let's Encrypt integration
+- Self-signed certificate generation for HTTPS testing
+- Unique port allocation to avoid conflicts
+- Proper server cleanup between tests
+- Both UDP and HTTPS query validation
+
+## Common Patterns
+
+1. **DNS Record Types**: Internally mapped to numeric values (A=1, AAAA=28, etc.)
+2. **Error Handling**: Graceful fallback and retry mechanisms
+3. **DNSSEC Workflow**: Zone → Key Generation → Signing → Verification
+4. **Certificate Flow**: Domain validation → Challenge setup → Verification → Certificate retrieval
+
+## Performance Considerations
+
+- Client implements caching via DNS-over-HTTPS responses
+- Server can handle concurrent UDP and HTTPS requests
+- DNSSEC signing is performed on-demand for efficiency
+- Handler registration is O(n) lookup but uses pattern caching
+
+## Security Notes
+
+- DNSSEC provides authentication but not encryption
+- DoH (DNS-over-HTTPS) provides both privacy and integrity
+- Let's Encrypt integration requires proper domain authorization
+- Handler patterns should be carefully designed to avoid open resolvers
+
+## Known Issues
+
+1. **DNSSEC RRSIG Generation**: When multiple records of the same type are returned, DNSSEC signing may encounter issues with the current implementation
+2. **SOA Record Prefix**: The server hardcodes 'ns1.' prefix for SOA mname field which may not match actual nameserver names
+3. **Handler Deduplication**: If the same handler is registered multiple times, it will contribute duplicate records

 ## Usage

-Use TypeScript for best in class instellisense.
+`@push.rocks/smartdns` is a comprehensive library that provides both DNS client and server capabilities, leveraging TypeScript for enhanced development experience. The library is organized into three modules:
+
+- **Client Module** (`@push.rocks/smartdns/client`): DNS resolution and record queries
+- **Server Module** (`@push.rocks/smartdns/server`): Full DNS server implementation with DNSSEC
+- **Main Module** (`@push.rocks/smartdns`): Convenience exports for both client and server
+
+### Getting Started
+
+You can import the modules based on your needs:

 ```typescript
-const mySmartDns = new smartdns.SmartDns(); // uses Google DNS Https API
-const demoRecord = await mySmartDns.getRecord('example.com', 'AAAA'); // returns promise
-/*
-demoRecord looks like this:
-{
-  name: 'example.com',
-  type: 'A',
-  dnsSecEnabled: true,
-  value: '104.24.103.243'
-}
-*/
+// For DNS client operations
+import { Smartdns } from '@push.rocks/smartdns/client';
+
+// For DNS server operations
+import { DnsServer } from '@push.rocks/smartdns/server';
+
+// Or import from the main module (note the different syntax)
+import { dnsClientMod, dnsServerMod } from '@push.rocks/smartdns';
+const dnsClient = new dnsClientMod.Smartdns({});
+const dnsServer = new dnsServerMod.DnsServer({ /* options */ });
 ```

-## Contribution
+### DNS Client Operations

-We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
+The DNS client (`Smartdns` class) provides methods to query various DNS record types using DNS-over-HTTPS (DoH) with Cloudflare as the primary provider, with fallback to Node.js DNS resolver.

+#### Fetching A Records

-## Legal
-> MIT licensed | **&copy;** [Task Venture Capital GmbH](https://task.vc)
-| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
+To fetch "A" records (IPv4 addresses) for a domain:
+
+```typescript
+import { Smartdns } from '@push.rocks/smartdns/client';
+
+const dnsClient = new Smartdns({});
+const aRecords = await dnsClient.getRecordsA('example.com');
+console.log(aRecords);
+// Output: [{ name: 'example.com', type: 'A', dnsSecEnabled: false, value: '93.184.215.14' }]
+```
+
+#### Fetching AAAA Records
+
+For resolving a domain to IPv6 addresses:
+
+```typescript
+const aaaaRecords = await dnsClient.getRecordsAAAA('example.com');
+console.log(aaaaRecords);
+// Output: [{ name: 'example.com', type: 'AAAA', dnsSecEnabled: false, value: '2606:2800:21f:cb07:6820:80da:af6b:8b2c' }]
+```
+
+#### Fetching TXT Records
+
+TXT records store text data, commonly used for domain verification, SPF records, and other metadata:
+
+```typescript
+const txtRecords = await dnsClient.getRecordsTxt('example.com');
+console.log(txtRecords);
+// Output: [{ name: 'example.com', type: 'TXT', dnsSecEnabled: false, value: 'v=spf1 -all' }]
+```
+
+#### Other Record Types
+
+The client supports various other DNS record types:
+
+```typescript
+// MX records for mail servers
+const mxRecords = await dnsClient.getRecords('example.com', 'MX');
+
+// NS records for nameservers
+const nsRecords = await dnsClient.getNameServers('example.com');
+
+// Generic query method with retry support
+const records = await dnsClient.getRecords('example.com', 'CNAME', { retryCount: 3 });
+```
+
+### Advanced DNS Features
+
+#### Checking DNS Propagation
+
+The client provides a powerful method to verify DNS propagation globally, essential when making DNS changes:
+
+```typescript
+// Check if a specific DNS record has propagated
+const recordType = 'TXT';
+const expectedValue = 'verification=abc123';
+
+const isAvailable = await dnsClient.checkUntilAvailable(
+  'example.com',
+  recordType,
+  expectedValue,
+  50,    // Number of check cycles (default: 50)
+  500    // Interval between checks in ms (default: 500)
+);
+
+if (isAvailable) {
+  console.log('DNS record has propagated successfully!');
+} else {
+  console.log('DNS propagation timeout - record not found.');
+}
+```
+
+#### Configuring System DNS Provider
+
+You can configure Node.js to use a specific DNS provider for all DNS queries:
+
+```typescript
+// Import the standalone function
+import { makeNodeProcessUseDnsProvider } from '@push.rocks/smartdns/client';
+
+// Use Cloudflare DNS for all Node.js DNS operations
+makeNodeProcessUseDnsProvider('cloudflare');
+
+// Or use Google DNS
+makeNodeProcessUseDnsProvider('google');
+```
+
+### Real-World Use Cases
+
+#### DNS-Based Feature Flagging
+
+Use TXT records for dynamic feature toggles without redeployment:
+
+```typescript
+const txtRecords = await dnsClient.getRecordsTxt('features.example.com');
+const featureFlags = {};
+
+txtRecords.forEach(record => {
+  // Parse TXT records like "feature-dark-mode=true"
+  const [feature, enabled] = record.value.split('=');
+  featureFlags[feature] = enabled === 'true';
+});
+
+if (featureFlags['feature-dark-mode']) {
+  console.log('Dark mode is enabled!');
+}
+```
+
+#### Service Discovery
+
+Use DNS for service endpoint discovery:
+
+```typescript
+// Discover API endpoints via TXT records
+const serviceRecords = await dnsClient.getRecordsTxt('_services.example.com');
+
+// Discover mail servers
+const mxRecords = await dnsClient.getRecords('example.com', 'MX');
+const primaryMailServer = mxRecords
+  .sort((a, b) => a.priority - b.priority)[0]?.exchange;
+```
+
+### DNS Server Implementation
+
+The `DnsServer` class provides a full-featured DNS server with support for UDP, DNS-over-HTTPS (DoH), DNSSEC, and automatic SSL certificate management via Let's Encrypt.
+
+#### Basic DNS Server Setup
+
+Create a simple DNS server that responds to queries:
+
+```typescript
+import { DnsServer } from '@push.rocks/smartdns/server';
+
+const dnsServer = new DnsServer({
+  udpPort: 5333,      // UDP port for DNS queries
+  httpsPort: 8443,    // HTTPS port for DNS-over-HTTPS
+  httpsKey: 'path/to/key.pem',   // Required for HTTPS
+  httpsCert: 'path/to/cert.pem', // Required for HTTPS
+  dnssecZone: 'example.com'      // Optional: enable DNSSEC for this zone
+});
+
+// For enhanced security, bind to specific interfaces
+const secureServer = new DnsServer({
+  udpPort: 53,
+  httpsPort: 443,
+  httpsKey: 'path/to/key.pem',
+  httpsCert: 'path/to/cert.pem',
+  dnssecZone: 'example.com',
+  udpBindInterface: '127.0.0.1',    // Bind UDP to localhost only
+  httpsBindInterface: '127.0.0.1'   // Bind HTTPS to localhost only
+});
+
+// Register a handler for all subdomains of example.com
+dnsServer.registerHandler('*.example.com', ['A'], (question) => ({
+  name: question.name,
+  type: 'A',
+  class: 'IN',
+  ttl: 300,
+  data: '192.168.1.100',
+}));
+
+// Register a handler for TXT records
+dnsServer.registerHandler('example.com', ['TXT'], (question) => ({
+  name: question.name,
+  type: 'TXT',
+  class: 'IN',
+  ttl: 300,
+  data: 'v=spf1 include:_spf.example.com ~all',
+}));
+
+// Start the server
+await dnsServer.start();
+console.log('DNS Server started!');
+```
+
+### DNSSEC Support
+
+The DNS server includes comprehensive DNSSEC support with automatic key generation and record signing:
+
+```typescript
+import { DnsServer } from '@push.rocks/smartdns/server';
+
+const dnsServer = new DnsServer({
+  udpPort: 53,
+  httpsPort: 443,
+  dnssecZone: 'secure.example.com',  // Enable DNSSEC for this zone
+});
+
+// The server automatically:
+// 1. Generates DNSKEY records with ECDSA (algorithm 13)
+// 2. Creates DS records for parent zone delegation
+// 3. Signs all responses with RRSIG records
+// 4. Provides NSEC records for authenticated denial of existence
+
+// Register your handlers as normal - DNSSEC signing is automatic
+dnsServer.registerHandler('secure.example.com', ['A'], (question) => ({
+  name: question.name,
+  type: 'A',
+  class: 'IN',
+  ttl: 300,
+  data: '192.168.1.1',
+}));
+
+await dnsServer.start();
+
+// Query for DNSSEC records
+import { Smartdns } from '@push.rocks/smartdns/client';
+const client = new Smartdns({});
+const dnskeyRecords = await client.getRecords('secure.example.com', 'DNSKEY');
+const dsRecords = await client.getRecords('secure.example.com', 'DS');
+```
+
+#### Supported DNSSEC Algorithms
+
+The server supports multiple DNSSEC algorithms:
+- **ECDSAP256SHA256** (Algorithm 13) - Default, using P-256 curve
+- **ED25519** (Algorithm 15) - Modern elliptic curve algorithm
+- **RSASHA256** (Algorithm 8) - RSA-based signatures
+
+### Let's Encrypt Integration
+
+The DNS server includes built-in Let's Encrypt support for automatic SSL certificate management:
+
+```typescript
+import { DnsServer } from '@push.rocks/smartdns/server';
+
+const dnsServer = new DnsServer({
+  udpPort: 53,
+  httpsPort: 443,
+  httpsKey: '/path/to/letsencrypt/key.pem',   // Will be auto-generated
+  httpsCert: '/path/to/letsencrypt/cert.pem', // Will be auto-generated
+});
+
+// Retrieve Let's Encrypt certificate for your domain
+const result = await dnsServer.retrieveSslCertificate(
+  ['secure.example.com', 'www.secure.example.com'],
+  {
+    email: 'admin@example.com',
+    staging: false,  // Use production Let's Encrypt
+    certDir: './certs'
+  }
+);
+
+if (result.success) {
+  console.log('Certificate retrieved successfully!');
+}
+
+// The server automatically:
+// 1. Handles ACME DNS-01 challenges
+// 2. Creates temporary TXT records for domain validation  
+// 3. Retrieves and installs the certificate
+// 4. Restarts the HTTPS server with the new certificate
+
+await dnsServer.start();
+console.log('DNS Server with Let\'s Encrypt SSL started!');
+```
+
+### Manual Socket Handling
+
+The DNS server supports manual socket handling for advanced use cases like clustering, load balancing, and custom transport implementations. You can control UDP and HTTPS socket handling independently.
+
+#### Configuration Options
+
+```typescript
+export interface IDnsServerOptions {
+  // ... standard options ...
+  manualUdpMode?: boolean;    // Handle UDP sockets manually
+  manualHttpsMode?: boolean;  // Handle HTTPS sockets manually
+}
+```
+
+#### Basic Manual Socket Usage
+
+```typescript
+import { DnsServer } from '@push.rocks/smartdns/server';
+import * as dgram from 'dgram';
+import * as net from 'net';
+
+// Create server with manual UDP mode
+const dnsServer = new DnsServer({
+  httpsKey: '...',
+  httpsCert: '...',
+  httpsPort: 853,
+  udpPort: 53,
+  dnssecZone: 'example.com',
+  manualUdpMode: true  // UDP manual, HTTPS automatic
+});
+
+await dnsServer.start(); // HTTPS binds, UDP doesn't
+
+// Create your own UDP socket
+const udpSocket = dgram.createSocket('udp4');
+
+// Handle incoming UDP messages
+udpSocket.on('message', (msg, rinfo) => {
+  dnsServer.handleUdpMessage(msg, rinfo, (response, responseRinfo) => {
+    // Send response using your socket
+    udpSocket.send(response, responseRinfo.port, responseRinfo.address);
+  });
+});
+
+// Bind to custom port or multiple interfaces
+udpSocket.bind(5353, '0.0.0.0');
+```
+
+#### Manual HTTPS Socket Handling
+
+```typescript
+// Create server with manual HTTPS mode
+const dnsServer = new DnsServer({
+  httpsKey: '...',
+  httpsCert: '...',
+  httpsPort: 853,
+  udpPort: 53,
+  dnssecZone: 'example.com',
+  manualHttpsMode: true  // HTTPS manual, UDP automatic
+});
+
+await dnsServer.start(); // UDP binds, HTTPS doesn't
+
+// Create your own TCP server
+const tcpServer = net.createServer((socket) => {
+  // Pass TCP sockets to DNS server
+  dnsServer.handleHttpsSocket(socket);
+});
+
+tcpServer.listen(8853, '0.0.0.0');
+```
+
+#### Full Manual Mode
+
+Control both protocols manually for complete flexibility:
+
+```typescript
+const dnsServer = new DnsServer({
+  httpsKey: '...',
+  httpsCert: '...',
+  httpsPort: 853,
+  udpPort: 53,
+  dnssecZone: 'example.com',
+  manualUdpMode: true,
+  manualHttpsMode: true
+});
+
+await dnsServer.start(); // Neither protocol binds
+
+// Set up your own socket handling for both protocols
+// Perfect for custom routing, load balancing, or clustering
+```
+
+#### Advanced Use Cases
+
+##### Load Balancing Across Multiple UDP Sockets
+
+```typescript
+// Create multiple UDP sockets for different CPU cores
+const sockets = [];
+const numCPUs = require('os').cpus().length;
+
+for (let i = 0; i < numCPUs; i++) {
+  const socket = dgram.createSocket({ 
+    type: 'udp4', 
+    reuseAddr: true  // Allow multiple sockets on same port
+  });
+  
+  socket.on('message', (msg, rinfo) => {
+    dnsServer.handleUdpMessage(msg, rinfo, (response, rinfo) => {
+      socket.send(response, rinfo.port, rinfo.address);
+    });
+  });
+  
+  socket.bind(53);
+  sockets.push(socket);
+}
+```
+
+##### Clustering with Worker Processes
+
+```typescript
+import cluster from 'cluster';
+import { DnsServer } from '@push.rocks/smartdns/server';
+
+if (cluster.isPrimary) {
+  // Master process accepts connections
+  const server = net.createServer({ pauseOnConnect: true });
+  
+  // Distribute connections to workers
+  server.on('connection', (socket) => {
+    const worker = getNextWorker(); // Round-robin or custom logic
+    worker.send('socket', socket);
+  });
+  
+  server.listen(853);
+} else {
+  // Worker process handles DNS
+  const dnsServer = new DnsServer({
+    httpsKey: '...',
+    httpsCert: '...',
+    httpsPort: 853,
+    udpPort: 53,
+    dnssecZone: 'example.com',
+    manualHttpsMode: true
+  });
+  
+  process.on('message', (msg, socket) => {
+    if (msg === 'socket') {
+      dnsServer.handleHttpsSocket(socket);
+    }
+  });
+  
+  await dnsServer.start();
+}
+```
+
+##### Custom Transport Protocol
+
+```typescript
+// Use DNS server with custom transport (e.g., WebSocket)
+import WebSocket from 'ws';
+
+const wss = new WebSocket.Server({ port: 8080 });
+const dnsServer = new DnsServer({
+  httpsKey: '...',
+  httpsCert: '...',
+  httpsPort: 853,
+  udpPort: 53,
+  dnssecZone: 'example.com',
+  manualUdpMode: true,
+  manualHttpsMode: true
+});
+
+await dnsServer.start();
+
+wss.on('connection', (ws) => {
+  ws.on('message', (data) => {
+    // Process DNS query from WebSocket
+    const response = dnsServer.processRawDnsPacket(Buffer.from(data));
+    ws.send(response);
+  });
+});
+```
+
+##### Multi-Interface Binding
+
+```typescript
+// Bind to multiple network interfaces manually
+const interfaces = [
+  { address: '192.168.1.100', type: 'udp4' },
+  { address: '10.0.0.50', type: 'udp4' },
+  { address: '::1', type: 'udp6' }
+];
+
+interfaces.forEach(({ address, type }) => {
+  const socket = dgram.createSocket(type);
+  
+  socket.on('message', (msg, rinfo) => {
+    console.log(`Query received on ${address}`);
+    dnsServer.handleUdpMessage(msg, rinfo, (response, rinfo) => {
+      socket.send(response, rinfo.port, rinfo.address);
+    });
+  });
+  
+  socket.bind(53, address);
+});
+```
+
+### Handling Different Protocols
+
+#### UDP DNS Server
+
+Traditional DNS queries over UDP (port 53):
+
+```typescript
+import { DnsServer } from '@push.rocks/smartdns/server';
+import * as plugins from '@push.rocks/smartdns/server/plugins';
+
+const dnsServer = new DnsServer({
+  udpPort: 5353,  // Using alternate port for testing
+  httpsPort: 8443,
+  httpsKey: fs.readFileSync('/path/to/key.pem', 'utf8'),
+  httpsCert: fs.readFileSync('/path/to/cert.pem', 'utf8'),
+  dnssecZone: 'test.local' // Optional
+});
+
+// The UDP server automatically handles DNS packet parsing and encoding
+dnsServer.registerHandler('test.local', ['A'], (question) => ({
+  name: question.name,
+  type: 'A', 
+  class: 'IN',
+  ttl: 60,
+  data: '127.0.0.1',
+}));
+
+await dnsServer.start();
+
+// Test with dig or nslookup:
+// dig @localhost -p 5353 test.local
+```
+
+#### DNS-over-HTTPS (DoH) Server
+
+Provide encrypted DNS queries over HTTPS:
+
+```typescript
+import { DnsServer } from '@push.rocks/smartdns/server';
+import * as fs from 'fs';
+
+const dnsServer = new DnsServer({
+  httpsPort: 8443,
+  httpsKey: fs.readFileSync('/path/to/key.pem', 'utf8'),
+  httpsCert: fs.readFileSync('/path/to/cert.pem', 'utf8'),
+});
+
+// The HTTPS server automatically handles:
+// - DNS wire format in POST body
+// - Proper Content-Type headers (application/dns-message)
+// - Base64url encoding for GET requests
+
+dnsServer.registerHandler('secure.local', ['A'], (question) => ({
+  name: question.name,
+  type: 'A',
+  class: 'IN', 
+  ttl: 300,
+  data: '10.0.0.1',
+}));
+
+await dnsServer.start();
+
+// Test with curl:
+// curl -H "Content-Type: application/dns-message" \
+//      --data-binary @query.bin \
+//      https://localhost:8443/dns-query
+```
+
+### Interface Binding
+
+For enhanced security and network isolation, you can bind the DNS server to specific network interfaces instead of all available interfaces.
+
+#### Localhost-Only Binding
+
+Bind to localhost for development or local-only DNS services:
+
+```typescript
+const localServer = new DnsServer({
+  udpPort: 5353,
+  httpsPort: 8443,
+  httpsKey: cert.key,
+  httpsCert: cert.cert,
+  dnssecZone: 'local.test',
+  udpBindInterface: '127.0.0.1',     // IPv4 localhost
+  httpsBindInterface: '127.0.0.1'
+});
+
+// Or use IPv6 localhost
+const ipv6LocalServer = new DnsServer({
+  // ... other options
+  udpBindInterface: '::1',           // IPv6 localhost
+  httpsBindInterface: '::1'
+});
+```
+
+#### Specific Interface Binding
+
+Bind to a specific network interface in multi-homed servers:
+
+```typescript
+const interfaceServer = new DnsServer({
+  udpPort: 53,
+  httpsPort: 443,
+  httpsKey: cert.key,
+  httpsCert: cert.cert,
+  dnssecZone: 'example.com',
+  udpBindInterface: '192.168.1.100',  // Specific internal interface
+  httpsBindInterface: '10.0.0.50'    // Different interface for HTTPS
+});
+```
+
+#### Security Considerations
+
+- **Default Behavior**: If not specified, servers bind to all interfaces (`0.0.0.0`)
+- **Localhost Binding**: Use `127.0.0.1` or `::1` for development and testing
+- **Production**: Consider binding to specific internal interfaces for security
+- **Validation**: Invalid IP addresses will throw an error during server startup
+
+### Advanced Handler Patterns
+
+#### Pattern-Based Routing
+
+Use glob patterns for flexible domain matching:
+
+```typescript
+// Match all subdomains
+dnsServer.registerHandler('*.example.com', ['A'], (question) => {
+  // Extract subdomain
+  const subdomain = question.name.replace('.example.com', '');
+  
+  // Dynamic response based on subdomain
+  return {
+    name: question.name,
+    type: 'A',
+    class: 'IN',
+    ttl: 300,
+    data: subdomain === 'api' ? '10.0.0.10' : '10.0.0.1',
+  };
+});
+
+// Match specific patterns
+dnsServer.registerHandler('db-*.service.local', ['A'], (question) => {
+  const instanceId = question.name.match(/db-(\d+)/)?.[1];
+  return {
+    name: question.name,
+    type: 'A',
+    class: 'IN',
+    ttl: 60,
+    data: `10.0.1.${instanceId}`,
+  };
+});
+
+// Catch-all handler
+dnsServer.registerHandler('*', ['A'], (question) => ({
+  name: question.name,
+  type: 'A', 
+  class: 'IN',
+  ttl: 300,
+  data: '127.0.0.1',
+}));
+```
+
+### Testing
+
+The library uses `@git.zone/tstest` for testing. Here's an example of comprehensive tests:
+
+```typescript
+import { expect, tap } from '@git.zone/tstest/tapbundle';
+import { Smartdns } from '@push.rocks/smartdns/client';
+import { DnsServer } from '@push.rocks/smartdns/server';
+
+// Test DNS Client
+tap.test('DNS Client - Query Records', async () => {
+  const dnsClient = new Smartdns({});
+  
+  // Test A record query
+  const aRecords = await dnsClient.getRecordsA('google.com');
+  expect(aRecords).toBeArray();
+  expect(aRecords[0]).toHaveProperty('type', 'A');
+  expect(aRecords[0].data).toMatch(/^\d+\.\d+\.\d+\.\d+$/);
+  
+  // Test TXT record query
+  const txtRecords = await dnsClient.getRecordsTxt('google.com');
+  expect(txtRecords).toBeArray();
+  expect(txtRecords[0]).toHaveProperty('type', 'TXT');
+});
+
+// Test DNS Server
+let dnsServer: DnsServer;
+

+
+### Best Practices
+
+1. **Port Selection**: Use non-privileged ports (>1024) during development
+2. **Handler Organization**: Group related handlers together
+3. **Error Handling**: Always handle DNS query errors gracefully
+4. **DNSSEC**: Enable DNSSEC for production deployments
+5. **Monitoring**: Log DNS queries for debugging and analytics
+6. **Rate Limiting**: Implement rate limiting for public DNS servers
+7. **Caching**: Respect TTL values and implement proper caching
+8. **Manual Sockets**: Use manual socket handling for clustering and load balancing
+
+### Performance Considerations
+
+- The DNS client uses HTTP keep-alive for connection reuse
+- The DNS server handles concurrent UDP and HTTPS requests efficiently
+- DNSSEC signatures are generated on-demand to reduce memory usage
+- Pattern matching uses caching for improved performance
+- Manual socket handling enables horizontal scaling across CPU cores
+
+### Security Considerations
+
+- Always use DNSSEC for authenticated responses
+- Enable DoH for encrypted DNS queries
+- Validate and sanitize all DNS inputs
+- Implement access controls for DNS server handlers
+- Use Let's Encrypt for automatic SSL certificate management
+- Never expose internal network information through DNS
+- Bind to specific interfaces in production environments
+- Use manual socket handling for custom security layers
+
+This comprehensive library provides everything needed for both DNS client operations and running production-grade DNS servers with modern security features in TypeScript.

+# SmartDNS Improvement Plan
+
+Command to reread CLAUDE.md: `cat /home/philkunz/.claude/CLAUDE.md`
+
+## Critical Issue: Support Multiple DNS Records of Same Type
+
+### Current Status: Planning
+**Priority: HIGH** - This issue blocks proper DNS server operation and domain registration
+
+### Problem Summary
+The DNS server currently exits after finding the first matching handler for a query, preventing it from serving multiple records of the same type (e.g., multiple NS records, multiple A records for round-robin, multiple TXT records).
+
+### Implementation Plan
+
+#### Phase 1: Analysis and Testing ✅ COMPLETED
+- [x] Create comprehensive test cases demonstrating the issue
+- [x] Test with multiple NS records scenario
+- [x] Test with multiple A records (round-robin) scenario
+- [x] Test with multiple TXT records scenario
+- [x] Document current behavior vs expected behavior
+
+#### Phase 2: Core Fix Implementation ✅ COMPLETED
+- [x] Remove the `break` statement in `processDnsRequest` method (line 609)
+- [x] Ensure all matching handlers are processed
+- [x] Accumulate all answers from matching handlers
+- [x] Add NS record serialization for DNSSEC support
+
+#### Phase 3: Handler Interface Enhancement (Optional)
+- [ ] Consider allowing handlers to return arrays of records
+- [ ] Update `IDnsHandler` interface to support `DnsAnswer | DnsAnswer[] | null`
+- [ ] Update processing logic to handle array responses
+- [ ] Maintain backward compatibility with existing handlers
+
+#### Phase 4: Testing and Validation
+- [ ] Test multiple NS records return correctly
+- [ ] Test round-robin DNS with multiple A records
+- [ ] Test multiple TXT records (SPF + DKIM + verification)
+- [ ] Test DNSSEC signatures for multiple records
+- [ ] Verify no regression in single-record scenarios
+
+#### Phase 5: Documentation and Examples
+- [ ] Update documentation with multiple record examples
+- [ ] Add example for registering multiple NS records
+- [ ] Add example for round-robin DNS setup
+- [ ] Document best practices for handler registration
+
+### Technical Details
+
+#### Current Code Issue (ts_server/classes.dnsserver.ts:609)
+```typescript
+answered = true;
+break; // <-- This prevents multiple handlers from contributing answers
+```
+
+#### Proposed Fix
+```typescript
+answered = true;
+// Continue processing other handlers instead of breaking
+```
+
+### Success Criteria
+- DNS queries return ALL matching records from ALL matching handlers
+- Domain registration with multiple NS records succeeds
+- Round-robin DNS works with multiple A records
+- Multiple TXT records can be served for the same domain
+- DNSSEC signatures are properly generated for all returned records
+
+### Implementation Summary
+
+#### What Was Fixed
+1. **Core Issue Resolved**: Removed the `break` statement at line 609 in `processDnsRequest` that was preventing multiple handlers from contributing DNS answers
+2. **NS Record Serialization**: Added NS record type support in `serializeRData` method for DNSSEC compatibility
+3. **Result**: DNS server now correctly returns multiple records of the same type from different handlers
+
+#### Test Results
+- ✅ Multiple NS records now work (2+ nameservers returned)
+- ✅ Round-robin DNS with multiple A records works
+- ✅ Multiple TXT records (SPF, DKIM, verification) work
+- ⚠️ DNSSEC RRSIG generation needs additional fixes for multiple record scenarios
+
+#### Code Changes
+```typescript
+// Before (line 609):
+answered = true;
+break;  // This was preventing multiple handlers from running
+
+// After:
+answered = true;
+// Continue processing other handlers to allow multiple records
+```
+
+### Additional Improvements to Consider
+1. Fix DNSSEC RRSIG generation for multiple records
+2. Fix SOA record timeout issues
+3. Make DNSSEC zone prefix configurable (remove hardcoded 'ns1.')
+4. Improve error handling for edge cases
+5. Consider handler interface enhancement to return arrays
