# Phase 1.1: IP Conflict Investigation Status **Date**: 2026-01-05 **IP Address**: 192.168.11.14 **Status**: 🔄 **IN PROGRESS** --- ## Investigation Steps ### Step 1: MAC Address Identification **Attempted Methods**: 1. ✅ Ping to 192.168.11.14 - **SUCCESS** (device responds) 2. ❌ ARP table lookup (local) - **NO ENTRY** (unusual - ARP entry missing) 3. ✅ Checking from ml110 - **SUCCESS** - Found MAC address 4. ✅ Network scan - **COMPLETE** **Findings**: - Device responds to ping (TTL=63, ~5-6ms latency) - **MAC Address**: `bc:24:11:ee:a6:ec` - **OUI (Vendor)**: `bc:24:11` (needs vendor lookup) - SSH banner shows Ubuntu (not Debian/Proxmox) - SSH port 22: OPEN - Proxmox port 8006: CLOSED (confirms NOT a Proxmox host) ### Step 2: Orphaned VM Check **Checked Hosts**: - ✅ ml110 (192.168.11.10) - No orphaned VMs found - ✅ r630-01 (192.168.11.11) - No orphaned VMs found - ✅ r630-02 (192.168.11.12) - No orphaned VMs found **Result**: No orphaned VMs found in cluster ### Step 3: Next Actions **Required**: 1. Get MAC address via router/switch ARP table 2. Check physical r630-04 server status 3. Verify if r630-04 is actually powered on 4. Check if device is on different network segment 5. Identify device type from MAC vendor **Alternative Methods**: - Check Omada controller for device information - Check router ARP table directly - Use network scanner if available - Physical inspection of r630-04 server --- ## Current Hypothesis **Most Likely Scenarios**: 1. **Orphaned VM/Container**: A VM or container running Ubuntu is using 192.168.11.14 but not registered in Proxmox cluster 2. **Different Device**: A different physical device (not r630-04) is using this IP 3. **r630-04 Running Ubuntu**: r630-04 was reinstalled with Ubuntu instead of Proxmox 4. **Network Device**: A switch, router, or other network device is using this IP --- ## Next Steps 1. **Check Router ARP Table** - Access ER605 router (192.168.11.1) - Check ARP table for 192.168.11.14 - Get MAC address 2. **Check Omada Controller** - Access Omada controller (192.168.11.20 or 192.168.11.8) - Check device list for 192.168.11.14 - Get device information 3. **Physical Inspection** - Check r630-04 physical server - Verify power status - Check console/iDRAC 4. **Network Scan** - Scan network for all devices - Identify which device has 192.168.11.14 --- **Last Updated**: 2026-01-05 **Next Update**: After MAC address identification
