+# DNS Server Configuration Fix Plan
+
+First command: `cat /home/centraluser/eu.central.ingress-2/CLAUDE.md`
+
+## Problem Summary
+The DNS server is logging "Dns Server starting on port undefined" because:
+1. The `smartdns.DnsServer` expects specific properties (`udpPort`, `httpsPort`, etc.) but something is trying to access `port`
+2. The `records` array we're passing isn't part of the DnsServer interface
+3. DnsServer uses a handler registration pattern, not a records array
+
+## Implementation Plan
+
+### 1. Fix DnsServer Interface Usage in DcRouter
+- [x] Update `dcrouter/ts/classes.dcrouter.ts` to properly handle DNS configuration
+- [x] Remove the `records` property from `IDnsServerOptions` type extension
+- [x] Create a new interface for DNS configuration that includes both DnsServer options and records
+
+### 2. Implement DNS Record Handler Registration
+- [x] After creating the DnsServer instance, register handlers for each DNS record
+- [x] Create a helper method `registerDnsRecords()` that takes the records array and registers appropriate handlers
+- [x] Use the DnsServer's `registerHandler()` method for each record type
+
+### 3. Find and Fix the Logging Issue
+- [x] Search for any logging that references `dnsServerConfig.port`
+- [x] Update to use `dnsServerConfig.udpPort` instead
+- [x] Check if the message is coming from within smartdns package or our code
+
+### 4. Create Proper Type Definitions
+- [x] Extend the dcrouter options to properly type DNS configuration
+- [x] Create interface that combines DnsServer options with our custom records array:
+  ```typescript
+  interface IDcRouterDnsConfig extends IDnsServerOptions {
+    records?: Array<{
+      name: string;
+      type: string;
+      value: string;
+      ttl?: number;
+    }>;
+  }
+  ```
+
+### 5. Update DcRouter DNS Setup Logic
+- [x] Modify `setupDnsServer()` method (or create if doesn't exist)
+- [x] Separate DnsServer instantiation from record registration
+- [x] Add proper error handling for DNS server startup
+
+### 6. Test the Implementation
+- [x] Create test file to verify DNS server starts correctly
+- [x] Test that all DNS records are properly registered
+- [x] Verify the port logging shows correct port number
+
+## Code Changes Required
+
+### File: `dcrouter/ts/classes.dcrouter.ts`
+
+1. Update the DNS server setup section (around line 117-122):
+   ```typescript
+   // Set up DNS server if configured
+   if (this.options.dnsServerConfig) {
+     const { records, ...dnsServerOptions } = this.options.dnsServerConfig;
+     this.dnsServer = new plugins.smartdns.DnsServer(dnsServerOptions);
+     
+     // Register DNS record handlers if records provided
+     if (records && records.length > 0) {
+       this.registerDnsRecords(records);
+     }
+     
+     await this.dnsServer.start();
+     console.log(`DNS server started on UDP port ${dnsServerOptions.udpPort}`);
+   }
+   ```
+
+2. Add new method for registering DNS records:
+   ```typescript
+   private registerDnsRecords(records: Array<{name: string; type: string; value: string; ttl?: number}>) {
+     if (!this.dnsServer) return;
+     
+     // Group records by domain pattern
+     const recordsByDomain = new Map<string, typeof records>();
+     
+     for (const record of records) {
+       const pattern = record.name.includes('*') ? record.name : `*.${record.name}`;
+       if (!recordsByDomain.has(pattern)) {
+         recordsByDomain.set(pattern, []);
+       }
+       recordsByDomain.get(pattern)!.push(record);
+     }
+     
+     // Register handlers for each domain pattern
+     for (const [domainPattern, domainRecords] of recordsByDomain) {
+       const recordTypes = [...new Set(domainRecords.map(r => r.type))];
+       
+       this.dnsServer.registerHandler(domainPattern, recordTypes, (question) => {
+         const matchingRecord = domainRecords.find(
+           r => r.name === question.name && r.type === question.type
+         );
+         
+         if (matchingRecord) {
+           return {
+             name: matchingRecord.name,
+             type: matchingRecord.type,
+             class: 'IN',
+             ttl: matchingRecord.ttl || 300,
+             data: this.parseDnsRecordData(matchingRecord.type, matchingRecord.value)
+           };
+         }
+         
+         return null;
+       });
+     }
+   }
+   ```
+
+3. Add helper method to parse DNS record data:
+   ```typescript
+   private parseDnsRecordData(type: string, value: string): any {
+     switch (type) {
+       case 'A':
+         return value; // IP address as string
+       case 'MX':
+         const [priority, exchange] = value.split(' ');
+         return { priority: parseInt(priority), exchange };
+       case 'TXT':
+         return value;
+       case 'NS':
+         return value;
+       default:
+         return value;
+     }
+   }
+   ```
+
+### File: `dcrouter/ts/config/index.ts` (if exists) or create type definition
+
+Add proper type definition for DNS configuration:
+```typescript
+export interface IDcRouterDnsConfig {
+  // Required DnsServer options
+  udpPort: number;
+  httpsPort: number;
+  httpsKey: string;
+  httpsCert: string;
+  dnssecZone: string;
+  
+  // Our custom records array
+  records?: Array<{
+    name: string;
+    type: 'A' | 'AAAA' | 'MX' | 'TXT' | 'NS' | 'CNAME' | 'SOA';
+    value: string;
+    ttl?: number;
+  }>;
+}
+```
+
+## Testing Strategy
+
+1. Create test file `dcrouter/test/test.dns-server-config.ts`
+2. Test DNS server starts without "undefined" port message
+3. Test DNS records are queryable after registration
+4. Test error handling when DNS server fails to start
+
+## Timeline
+- Step 1-3: Fix interface and logging (30 min)
+- Step 4-5: Implement proper record registration (45 min)
+- Step 6: Testing and verification (30 min)
+
+Total estimated time: ~2 hours
+
+## Success Criteria
+- [x] DNS server starts without "undefined" port message
+- [x] Shows correct port number in logs (e.g., "DNS server started on UDP port 53")
+- [x] All DNS records are properly registered and queryable
+- [x] No type errors or runtime errors
+- [x] Integration with DKIM auto-registration still works
+
+## ✅ COMPLETED
+All tasks have been successfully implemented. The DNS server configuration is now properly handled in dcrouter.
