## Configure bootnodes in a production network

A network must have at least one operating bootnode. To allow for continuity in the event of failure, configure two or more bootnodes in a production network.
A network must have at least one operating bootnode. To allow for continuity in the event of failure, configure two or more bootnodes in a production network. If you don't configure any bootnodes, Besu uses Mainnet's default bootnodes.

We don't recommend putting bootnodes behind a load balancer because the [enode](../../../public-networks/concepts/node-keys.md#enode-url) relates to the node public key, IP address, and discovery ports. Any changes to a bootnode enode prevents other nodes from being able to establish a connection with the bootnode. This is why we recommend putting more bootnodes on the network itself.
