| `EndpointAddress`                       | `127.0.0.1:0`      | 0                     | 0                       |

**Description:**

Configures the address where the node listens for [REST API](https://specs.algorand.co/node/non-normative/node-nn-api) calls.
It may hold an `IP:port` pair or just a `port`. The value `127.0.0.1:0` and `:0`
will attempt to bind to port `8080` if possible; otherwise, it will bind to a random
port. Any other address ending in `:0` will bind directly to a random port.
