# VZNetworkDeviceAttachment

The common behaviors for the network attachment points of your virtual machine.

```
class VZNetworkDeviceAttachment
```

## Overview

Don’t create a [`VZNetworkDeviceAttachment`](/documentation/Virtualization/VZNetworkDeviceAttachment) object directly. Instead, instantiate one of its concrete subclasses and use that object to configure your network devices. Each concrete subclass represents a specific type of network interface on the host computer.
