# MQTT

![The Project Settings MQTT Attributes.](/files/flKFiMwp6ZWkT6C5A0Bd)

The **MQTT Settings** allow to manage the **MQTT Connections** and cover the necessary data to provide functionality to the [**MQTT Nodes**](/incari-studio/2022.2/toolbox/communication/mqtt.md).

`Name` is an identifying name of an *MQTT* connection chosen at the user's discretion.

`Is IPv6` can be enabled or disabled. *IPv6* is the newest version of the *Internet Protocol*. More information about *IPv6* can be found in the **External Links** section.

`Remote IP address` is the IP address from which the connection originates.

`Remote port` is the port number of the connection. For *MQTT*, the standard is 1883.

`Autostart` can be enabled or disabled and dictates when the connection is run (from the beginning of an application's life cycle or when the appropriate **Nodes** are used).
