Network
Connectivity
To synchronize the state, the node needs to establish connections with other nodes that have already joined the network. Ensure that port 8084 is open and set up an external address for node discovery.
The full node uses the following ports by default:
Default Firewall Ports
Make sure to open these ports in your firewall configuration.
(These are the defaults, but may vary for a custom setup)
| Protocol/Port | Reachability | Purpose | Description |
|---|---|---|---|
| TCP/8080 | Outbound | Validator/transaction interface | full nodes connect to validators to collect partial signatures for transactions |
| UDP/8084 | Inbound/Outbound | Peer-to-peer state sync interface | nodes sync their state with each other |
| TCP/9000 | Inbound | JSON RPC endpoint / Web socket (optional) | API for interaction with the network |
| TCP/9184 | Localhost | Prometheus metrics scraping | for local monitoring only |
Known peers
By default, your config file (fullnode.yaml) should include the following known peers (from public nodes run by the IOTA Foundation):
- Mainnet
- Testnet
- Devnet
