![The Project Settings MQTT Attributes.](https://2561100106-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Ff6JZovzOqBctA4C1o76u%2Fuploads%2Fgit-blob-4ee6962ea26119fd618b19afb0dc0ab444f8f296%2Fprojectsettingsmqtt20232.png?alt=media)

The **MQTT Settings** allow the user to manage the **MQTT Connections** and cover the necessary data to provide functionality to the [**MQTT Nodes**](https://docs.incari.com/incari-studio/2023.2/toolbox/communication/mqtt).

`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.

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

`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).
