## 2. Validation results
|
|||
|
|
|
|||
|
|
| Check | Result |
|
|||
|
|
|-------|--------|
|
|||
|
|
| **DNS** | Public hostnames resolve to 76.53.10.36 |
|
|||
|
|
| **TLS** | Valid Let's Encrypt; CN matches hostname; TLS 1.3 |
|
|||
|
|
| **Proxy** | NPMplus routes by Host to VMID 2201 |
|
|||
|
|
| **Upstream** | Besu RPC (192.168.11.221:8545 / :8546) reachable and responsive |
|
|||
|
|
| **RPC** | `eth_chainId` returns `0x8a` (138) |
|
|||
|
|
| **Chain** | Defi Oracle Meta Mainnet – sovereign EVM, no mainnet/testnet collision |
|
|||
|
|
|
|||
|
|
**Validation command** (from a host that can reach NPMplus, e.g. LAN with Split DNS or `--resolve`):
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
curl -sk --resolve rpc-http-pub.d-bis.org:443:192.168.11.167 \
|
|||
|
|
https://rpc-http-pub.d-bis.org \
|
|||
|
|
-H "Content-Type: application/json" \
|
|||
|
|
-d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'
|
|||
|
|
# Expected: {"jsonrpc":"2.0","id":1,"result":"0x8a"}
|
|||
|
|
```

## 4. Operational notes
|
|||
|
|
|
|||
|
|
- **LAN access**: From inside the same network, public hostnames may not resolve back (NAT hairpin). Use Split DNS (internal A records to 192.168.11.167) or the `--resolve` curl pattern for testing.
|
|||
|
|
- **Port forwarding**: 76.53.10.36:80 and :443 → 192.168.11.167 (NPMplus). Confirmed on UDM Pro.
|
|||
|
|
- **No auth**: Public RPC endpoints do not require API keys or auth.
