description: Pantheon network ID and chain ID implementation
<!--- END of page meta data -->
# Network ID and Chain ID
Nc 2026 network option (#645) fixes NC-2026 adds a `--network` option instead of separated options Networks are now defined using a `--network` option that takes the case insensitive name of an enum values as input : MAINNET, RINKEBY, ROPSTEN, GOERLI, DEV These presets are a set of network-id, genesis file and boonodes list. If the `--genesis-file` is provided with a valid JSON genesis file, Pantheon uses it instead of the default network. An empty bootnodes list is then the default value and network id is the chain id found in the genesis file. `--network-id` and `--bootnodes` options can override these defaults. You can of course also override the `--network-id` and `--bootnodes` for a predefined known network (using `--network`). User have no reason to set `--network` and `--genesis-file` options at the same time that would lead to misunderstandings so we raise an error to prevent both options to be defined at the same time on the command line. Also fixes NC-2189 renaming --private-genesis-file to --genesis-file Updates a lot of doc according to the options changes Signed-off-by: Adrian Sutton <adrian.sutton@consensys.net>

Ethereum networks have a **network ID** and a **chain ID**. The network ID can be specified using the
[`--network-id`](../Reference/Pantheon-CLI-Syntax.md#network-id) option and the chain ID is specified
in the genesis file.

The network ID is automatically set by Pantheon to the chain ID when connecting to the Ethereum networks:

- **MainNet:** chain-id ==1==, network-id ==1==
- **Rinkeby:** chain-id ==4==, network-id ==4==
- **Ropsten:** chain-id ==3==, network-id ==3==
- **Dev:** chain-id ==2018==, network-id ==2018==
When using the [`--network=dev`](../Reference/Pantheon-CLI-Syntax.md#network) or
[`--genesis-file`](../Reference/Pantheon-CLI-Syntax.md#genesis-file) options, you can override the
network ID using the [`--network-id`](../Reference/Pantheon-CLI-Syntax.md#network-id) option.
