 The `hosts` section defines all machines, VMs, containers, or Docker services that WoL Redirect can wake up. Each host entry may have several optional or required fields depending on its type.

-| `ip`           | string  | Yes                      | The IP address of the host. Required for all types.                             |
-| `mac`          | string  | Required for PHYSICAL    | MAC address for Wake-on-LAN. Only needed for physical hosts.                    |

-## Host Type Inference
+### Host Type Inference
 
 - **PHYSICAL** → has `mac` and `ip`
 - **VIRTUAL** → has `id`
 - **DOCKER** → has `docker` object or `docker: true`
 
-## Notes on Optional Overrides
+### Notes on Optional Overrides
 
+- `addr` allows sending WoL packets to a different network address than `ip`, useful for hosts behind different subnets or NAT.
 - `url` can override default helper URLs for PHYSICAL, VIRTUAL, or DOCKER hosts.
 - `virtIP` can override the IP used by virtual helper services.
 - `docker.queryPattern` can override the global `ENV.woldQueryPattern`.
