Yes, you can dynamically add/remove nodes with the 'start role' and 'stop role' console commands (see [[MckoiDDB Console Reference]]). You may need to update the network configuration file across your cluster when adding nodes to ensure the node's ip address is included in the whitelist. The node application will notice when the configuration file is changed and update its internal state appropriately without having to be restarted.

You may also host the 'network.conf' on a web server for centralized administration of the node whitelist.
