# 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
