+# 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
+- Handler chaining for complex scenarios
+- Automatic SOA response for unhandled queries
+
+## 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

-Make sure you have a TypeScript environment setup to utilize the library effectively.
 
 ## Usage
 
-`@push.rocks/smartdns` is a comprehensive library aimed at facilitating smart DNS operations, leveraging TypeScript for enhanced development experience. This section aims to cover several real-world scenarios demonstrating the library's capabilities, from basic DNS lookups to more advanced DNS management tasks.
+`@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
 
-First, ensure you import the module into your TypeScript project:
+You can import the modules based on your needs:
 
 ```typescript
-import { Smartdns } from '@push.rocks/smartdns';
+// 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 */ });
 ```
 
-### Basic DNS Record Lookup
+### DNS Client Operations
 
-Often, the need arises to fetch various DNS records for a domain. `@push.rocks/smartdns` simplifies this by providing intuitive methods.
+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
 
-To fetch an "A" record for a domain:
+To fetch "A" records (IPv4 addresses) for a domain:
 
 ```typescript
-const dnsManager = new Smartdns({});
+import { Smartdns } from '@push.rocks/smartdns/client';
-const aRecords = await dnsManager.getRecordsA('example.com');
+
+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
 
-Similarly, for "AAAA" records:
+For resolving a domain to IPv6 addresses:
 
 ```typescript
-const aaaaRecords = await dnsManager.getRecordsAAAA('example.com');
+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' }]
 ```
 
-### Advanced DNS Management
+#### Fetching TXT Records
 
-Beyond simple queries, `@push.rocks/smartdns` offers functionalities suitable for more complex DNS management scenarios.
+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
 
-When changing DNS records, ensuring that the new records have propagated fully is crucial. `@push.rocks/smartdns` facilitates this with a method to check a DNS record until it is available globally.
+The client provides a powerful method to verify DNS propagation globally, essential when making DNS changes:
 
 ```typescript
-const recordType = 'TXT'; // Record type: A, AAAA, CNAME, TXT etc.
+// Check if a specific DNS record has propagated
-const expectedValue = 'your_expected_value';
+const recordType = 'TXT';
-const isAvailable = await dnsManager.checkUntilAvailable('example.com', recordType, expectedValue);
+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('Record propagated successfully.');
+  console.log('DNS record has propagated successfully!');
 } else {
-  console.log('Record propagation failed or timed out.');
+  console.log('DNS propagation timeout - record not found.');
 }
 ```
 
-### Leveraging DNS for Application Logic
+#### Configuring System DNS Provider
 
-DNS records can serve beyond mere domain-to-IP resolution; they can be instrumental in application logic, such as feature flagging or environment-specific configurations.
+You can configure Node.js to use a specific DNS provider for all DNS queries:
-
-#### Example: Feature Flagging via TXT Records
-
-Consider leveraging TXT records for enabling/disabling features dynamically without deploying new code.
 
 ```typescript
-const txtRecords = await dnsManager.getRecordsTxt('features.example.com');
+// Import the standalone function
-const featureFlags = txtRecords.reduce((acc, record) => {
+import { makeNodeProcessUseDnsProvider } from '@push.rocks/smartdns/client';
-  const [flag, isEnabled] = record.value.split('=');
-  acc[flag] = isEnabled === 'true';
-  return acc;
-}, {});
 
-if (featureFlags['NewFeature']) {
+// Use Cloudflare DNS for all Node.js DNS operations
-  // Logic to enable the new feature
+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!');
 }
 ```

+```
 
+### 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({

+```
+
+### 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;
+
+tap.test('DNS Server - Setup and Start', async () => {
+  dnsServer = new DnsServer({
+    udpPort: 5353,
+    httpsPort: 8443,
+    httpsKey: 'test-key',   // Use test certificates
+    httpsCert: 'test-cert',
+    dnssecZone: 'test.local'
+  });
+  
+  expect(dnsServer).toBeInstanceOf(DnsServer);
+  await dnsServer.start();
+});
+
+tap.test('DNS Server - Register Handlers', async () => {
+  // Register multiple handlers
+  dnsServer.registerHandler('test.local', ['A'], () => ({
+    name: 'test.local',
+    type: 'A',
+    class: 'IN',
+    ttl: 300,
+    data: '127.0.0.1',
+  }));
+  
+  dnsServer.registerHandler('*.test.local', ['A'], (question) => ({
+    name: question.name,
+    type: 'A', 
+    class: 'IN',
+    ttl: 60,
+    data: '127.0.0.2',
+  }));
+});
+
+tap.test('DNS Server - Query via UDP', async (tools) => {
+  const dnsPacket = (await import('dns-packet')).default;
+  const dgram = await import('dgram');
+  
+  const query = dnsPacket.encode({
+    type: 'query',
+    id: 1234,
+    questions: [{
+      type: 'A',
+      class: 'IN', 
+      name: 'test.local',
+    }],
+  });
+  
+  const client = dgram.createSocket('udp4');
+  const done = tools.defer();
+  
+  client.on('message', (msg) => {
+    const response = dnsPacket.decode(msg);
+    expect(response.answers[0].data).toEqual('127.0.0.1');
+    client.close();
+    done.resolve();
+  });
+  
+  client.send(query, 5353, 'localhost'); // Use the port specified during server creation
+  await done.promise;
+});
+
+tap.test('DNS Server - Cleanup', async () => {
+  await dnsServer.stop();
+});
+
+// Run tests
+await tap.start();
+```
+
+### 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
+
+### 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
+
+### 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
+
+This comprehensive library provides everything needed for both DNS client operations and running production-grade DNS servers with modern security features in TypeScript.

+# DNS Server Interface Binding Implementation Plan
+
+Command to reread CLAUDE.md: `cat /home/philkunz/.claude/CLAUDE.md`
+
+## Overview ✅ COMPLETED
+Enable specific interface binding for the DNSServer class to allow binding to specific network interfaces instead of all interfaces (0.0.0.0).
+
+## Implementation Status: COMPLETED ✅
+
+### What was implemented:
+
+✅ **1. Updated IDnsServerOptions Interface**
+- Added optional `udpBindInterface?: string` property (defaults to '0.0.0.0')
+- Added optional `httpsBindInterface?: string` property (defaults to '0.0.0.0')
+- Located in `ts_server/classes.dnsserver.ts:5-11`
+
+✅ **2. Modified DnsServer.start() Method**
+- Updated UDP server binding to use `this.options.udpBindInterface || '0.0.0.0'`
+- Updated HTTPS server listening to use `this.options.httpsBindInterface || '0.0.0.0'`
+- Added IP address validation before binding
+- Updated console logging to show specific interface being bound
+- Located in `ts_server/classes.dnsserver.ts:699-752`
+
+✅ **3. Added IP Address Validation**
+- Created `isValidIpAddress()` method supporting IPv4 and IPv6
+- Validates interface addresses before binding
+- Throws meaningful error messages for invalid addresses
+- Located in `ts_server/classes.dnsserver.ts:392-398`
+
+✅ **4. Updated Documentation**
+- Added dedicated "Interface Binding" section to readme.md
+- Included examples for localhost-only binding (`127.0.0.1`, `::1`)
+- Documented security considerations and use cases
+- Added examples for specific interface binding
+
+✅ **5. Added Comprehensive Tests**
+- **localhost binding test**: Verifies binding to `127.0.0.1` instead of `0.0.0.0`
+- **Invalid IP validation test**: Ensures invalid IP addresses are rejected
+- **IPv6 support test**: Tests `::1` binding (with graceful fallback if IPv6 unavailable)
+- **Backwards compatibility**: Existing tests continue to work with default behavior
+- Located in `test/test.server.ts`
+
+✅ **6. Updated restartHttpsServer Method**
+- Modified to respect interface binding options during certificate updates
+- Ensures Let's Encrypt certificate renewal maintains interface binding
+
+## ✅ Implementation Results
+
+### Test Results
+All interface binding functionality has been successfully tested:
+
+```bash
+✅ should bind to localhost interface only (318ms)
+   - UDP DNS server running on 127.0.0.1:8085
+   - HTTPS DNS server running on 127.0.0.1:8084
+
+✅ should reject invalid IP addresses (151ms)
+   - Validates IP address format correctly
+   - Throws meaningful error messages
+
+✅ should work with IPv6 localhost if available
+   - Gracefully handles IPv6 unavailability in containerized environments
+```
+
+### Benefits Achieved
+- ✅ Enhanced security by allowing localhost-only binding
+- ✅ Support for multi-homed servers with specific interface requirements
+- ✅ Better isolation in containerized environments
+- ✅ Backwards compatible (defaults to current behavior)
+- ✅ IP address validation with clear error messages
+- ✅ IPv4 and IPv6 support
+
+## Example Usage (Now Available)
+```typescript
+// Bind to localhost only
+const dnsServer = new DnsServer({
+  httpsKey: cert.key,
+  httpsCert: cert.cert,
+  httpsPort: 443,
+  udpPort: 53,
+  dnssecZone: 'example.com',
+  udpBindInterface: '127.0.0.1',
+  httpsBindInterface: '127.0.0.1'
+});
+
+// Bind to specific interface
+const dnsServer = new DnsServer({
+  // ... other options
+  udpBindInterface: '192.168.1.100',
+  httpsBindInterface: '192.168.1.100'
+});
+```
+
+## Files to Modify
+1. `ts_server/classes.dnsserver.ts` - Interface and implementation
+2. `readme.md` - Documentation updates
+3. `test/test.server.ts` - Add interface binding tests
+
+## Testing Strategy
+- Unit tests for interface validation
+- Integration tests for binding behavior
+- Error handling tests for invalid interfaces
+- Backwards compatibility tests
