 Bootnodes and static nodes are parallel methods for finding peers. Depending on your use case, you can use only bootnodes, only static nodes, or both bootnodes and static nodes.

 To find peers, configure one or more bootnodes. To configure a specific set of peer connections, use [static nodes](../../../public-networks/how-to/connect/static-nodes.md).

 For example:
 * You run multiple nodes on Mainnet, using bootnodes for discovery, but want to ensure your nodes are always connected to each other, using static nodes.
 * You run a small network and want your nodes to reconnect if disconnected, using static nodes.
