## A static file or list of nodes
> ***Warning*** This discovery method is not compatible with replicating swarm masters, so if you require replication, you will need to use a hosted discovery key store.
You can use a static file or list of nodes for your discovery backend. The file must be stored on a host that is accessible from the Swarm manager. You can also pass a node list as an option when you start Swarm.
Both the static file and the `nodes` option support a IP address ranges. To specify a range supply a pattern, for example, `10.0.0.[10:200]` refers to nodes starting from `10.0.0.10` to `10.0.0.200`. For example for the `file` discovery method.
