+# 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

+# 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
