# Dev VM (5700) IP change: 192.168.11.60 → 192.168.11.59

**Date:** 2026-02  
**Reason:** Resolve IP conflict with VMID 3000 (ML node) at 192.168.11.60.

## Repo changes (done)

- **config/ip-addresses.conf:** `IP_DEV_VM="192.168.11.59"`
- All docs and scripts referencing Dev VM IP updated to .59.
- NPMplus Fourth proxy script uses `IP_DEV_VM` from config → **gitea.d-bis.org**, **dev.d-bis.org**, **codespaces.d-bis.org** will forward to 192.168.11.59:3000 after you run the proxy update.

## On Proxmox (operator)

If LXC 5700 already exists and is still using 192.168.11.60, reconfigure it to use .59:

1. **From Proxmox host (r630-01):**
   ```bash
   pct set 5700 --net0 name=eth0,bridge=vmbr0,ip=192.168.11.59/24,gw=192.168.11.1
   pct reboot 5700
   ```
2. Or edit the CT’s network inside the container (e.g. netplan or /etc/network/interfaces) and reboot.

3. **Update NPMplus Fourth** so proxy hosts point to the new IP:
   ```bash
   NPM_PASSWORD=xxx bash scripts/nginx-proxy-manager/update-npmplus-fourth-proxy-hosts.sh
   ```
   (Script reads `IP_DEV_VM` from config, so no change needed if you sourced config.)

4. **UDM Pro:** If you had port forward 22 → 192.168.11.60, change it to 22 → 192.168.11.59.

## E2E

- **gitea.d-bis.org**, **dev.d-bis.org**, **codespaces.d-bis.org** are included in `scripts/verify/verify-end-to-end-routing.sh`.
- They are expected to resolve to **76.53.10.40** (Fourth NPMplus) and are tested as web (DNS, SSL, HTTPS).
