The running node will display it's ENR as a base64 string. This ENR, by default, has a target address of `127.0.0.1` meaning that any new node will connect to this node via `127.0.0.1`. If a boot node should be connected to on a different address, it should be run with the `--discovery-address` CLI flag to specify how other nodes may connect to it.

Here <boot-node-ENR> is the ENR string displayed in the terminal from the first node. The ENR can also be obtained from it's default directory `.lighthouse/network/enr.dat`.

The `--datadir` flag tells this Beacon Node to store it's files in a different
directory. If you're on a system that doesn't have a `/tmp` dir (e.g., Mac,
Windows), substitute this with any directory that has write access.
Note that all future created nodes can use the same boot-node ENR. Once connected to the boot node, all nodes should discover and connect with each other.
