# 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
## Recent Improvements (v7.4.3)
1. **DNSSEC RRset Signing**: Fixed to properly sign entire RRsets together instead of individual records
2. **SOA Record Serialization**: Implemented proper SOA record encoding for DNSSEC compatibility
3. **Configurable Primary Nameserver**: Added `primaryNameserver` option to customize SOA mname field
## Recent Improvements (v7.4.8)
1. **MX Record DNSSEC Support**: Implemented MX record serialization for DNSSEC signing
- MX records consist of a 16-bit preference value followed by the exchange domain name
- Properly serializes both components for DNSSEC signature generation
- Enables mail exchange records to be authenticated with DNSSEC
## Known Limitations
1. **Handler Deduplication**: If the same handler is registered multiple times, it will contribute duplicate records (this may be desired behavior for some use cases)

```
Make sure you have a TypeScript environment setup to utilize the library effectively.
Make sure you have a TypeScript environment set up 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({});
const aRecords = await dnsManager.getRecordsA('example.com');
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
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.
const expectedValue = 'your_expected_value';
const isAvailable = await dnsManager.checkUntilAvailable('example.com', recordType, expectedValue);
// 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('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.
#### Example: Feature Flagging via TXT Records
Consider leveraging TXT records for enabling/disabling features dynamically without deploying new code.
You can configure Node.js to use a specific DNS provider for all DNS queries:
```typescript
const txtRecords = await dnsManager.getRecordsTxt('features.example.com');
const featureFlags = txtRecords.reduce((acc, record) => {
const [flag, isEnabled] = record.value.split('=');
acc[flag] = isEnabled === 'true';
return acc;
}, {});
// Import the standalone function
import { makeNodeProcessUseDnsProvider } from '@push.rocks/smartdns/client';
if (featureFlags['NewFeature']) {
// Logic to enable the new feature
// 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!');
}
```
### Conclusion
#### Service Discovery
`@push.rocks/smartdns` offers a versatile set of tools for DNS querying and management, tailored for applications at any scale. The examples provided illustrate the library's potential use cases, highlighting its applicability in various scenarios from basic lookups to facilitating complex application features through DNS.
Use DNS for service endpoint discovery:
For the full spectrum of functionalities, including detailed method documentation and additional use cases, consult the module's [TypeDoc documentation](https://pushrocks.gitlab.io/smartdns/). This will serve as a comprehensive guide to leveraging `@push.rocks/smartdns` effectively in your projects.
```typescript
// Discover API endpoints via TXT records
const serviceRecords = await dnsClient.getRecordsTxt('_services.example.com');
Remember, DNS changes might take time to propagate worldwide, and the utility methods provided by `@push.rocks/smartdns` for checking record availability will be invaluable in managing these changes seamlessly.
// 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
primaryNameserver: 'ns1.example.com' // Optional: primary nameserver for SOA records (defaults to ns1.{dnssecZone})
});
// 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!');
```
### SOA Records and Primary Nameserver
The DNS server automatically generates SOA (Start of Authority) records for zones when no specific handler matches a query. The SOA record contains important zone metadata including the primary nameserver.
```typescript
const dnsServer = new DnsServer({
udpPort: 53,
httpsPort: 443,
httpsKey: 'path/to/key.pem',
httpsCert: 'path/to/cert.pem',
dnssecZone: 'example.com',
primaryNameserver: 'ns1.example.com' // Specify your actual primary nameserver
});
// Without primaryNameserver, the SOA mname defaults to 'ns1.{dnssecZone}'
// In this case, it would be 'ns1.example.com'
// The automatic SOA record includes:
// - mname: Primary nameserver (from primaryNameserver option)
// - rname: Responsible person email (hostmaster.{dnssecZone})
// - serial: Unix timestamp
// - refresh: 3600 (1 hour)
// - retry: 600 (10 minutes)
// - expire: 604800 (7 days)
// - minimum: 86400 (1 day)
```
**Important**: Even if you have multiple nameservers (NS records), only one is designated as the primary in the SOA record. All authoritative nameservers should return the same SOA record.
### 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 {
httpsKey: string; // Path or content of HTTPS private key
httpsCert: string; // Path or content of HTTPS certificate
httpsPort: number; // Port for DNS-over-HTTPS
udpPort: number; // Port for standard UDP DNS
dnssecZone: string; // Zone name for DNSSEC signing
udpBindInterface?: string; // IP address to bind UDP socket (default: '0.0.0.0')
httpsBindInterface?: string; // IP address to bind HTTPS server (default: '0.0.0.0')
manualUdpMode?: boolean; // Handle UDP sockets manually
manualHttpsMode?: boolean; // Handle HTTPS sockets manually
primaryNameserver?: string; // Primary nameserver for SOA records (default: 'ns1.{dnssecZone}')
}
```
#### 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;
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
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.
