# IP Centralization Tracking

**Last Updated:** 2026-01-31  
**Purpose:** Track scripts/docs using hardcoded IPs for migration to centralized config

## Source of Truth

| Variable | Value | Scope |
|----------|-------|-------|
| PROXMOX_ML110 | 192.168.11.10 | ml110 host |
| PROXMOX_R630_01 | 192.168.11.11 | r630-01 host |
| PROXMOX_R630_02 | 192.168.11.12 | r630-02 host |
| NPM_URL | https://192.168.11.167:81 | NPMplus (VMID 10233) |

**Tezos/Etherlink/Jumper:** See .env.example (ETHERLINK_RPC_URL, TEZOS_RPC_URL, JUMPER_API_KEY, etc.). [TEZOS_NETWORK_CONFIG_ENV_MATRIX](../../07-ccip/TEZOS_NETWORK_CONFIG_ENV_MATRIX.md).

## Scripts Using Hardcoded IPs

- **scripts/verify/verify-backend-vms.sh** – VM_CONFIGS with host IPs
- **scripts/verify/backup-npmplus.sh** – NPMPLUS_HOST, NPM_URL
- **scripts/deployment/phase*.sh** – Proxmox host references
- **~590 scripts** – grep for 192.168.11, 76.53.10.34

## .env Variables (add to .env.example)

```
PROXMOX_ML110=192.168.11.10
PROXMOX_R630_01=192.168.11.11
PROXMOX_R630_02=192.168.11.12
NPM_URL=https://192.168.11.167:81
NPMPLUS_HOST=192.168.11.11
NPMPLUS_VMID=10233
```

## Migration Approach

1. Add PROXMOX_* and NPM_* to `.env.example` (see above)
2. Source from env in scripts: `source .env 2>/dev/null || true`
3. Replace literals with `${VAR:-default}`
4. Update docs referencing IPs to point to this file

## Status

| Phase | Status |
|-------|--------|
| Document created | ✅ Done |
| .env.example vars | ✅ Done |
| Script migration | ✅ Done (676 via centralize; fix-remaining completed all active-script bare IPs; archive excluded. Remaining refs are in \`\${VAR:-ip}\` fallbacks or doc strings using \`\${NETWORK_PREFIX}.X\`.) |
| Doc updates | ⏳ Pending |
