# @ohos.enterprise.networkManager (Network Management)

The **networkManager** module provides APIs for network management of enterprise devices, including obtaining the device IP address and MAC address.

> **NOTE**
>
> The initial APIs of this module are supported since API version 12. Newly added APIs will be marked with a superscript to indicate their earliest API version.
>
> The APIs of this module can be used only in the stage model.
>
> The APIs of this module can be called only by a [device administrator application](../../mdm/mdm-kit-guide.md#introduction) that is enabled.
