# __machineName

*Also documented in context in the [full Functions and Variables reference](/user-manual/functions/#__machineName).*

The machineName function returns the local host name. This uses the Java method `InetAddress.getLocalHost()` and passes it to `getHostName()`

| Name | Required | Description |
| --- | --- | --- |
| Variable Name | No | A reference name for reusing the value                 computed by this function. |

Examples:

```bash
\${__machineName()}
```

will return the host name of the machine

```bash
\${__machineName}
```

will return the host name of the machine
