| Inheritance | NetworkInfo  EventDispatcher Object |

AIR profile support: This feature is supported
on all desktop operating systems and AIR for TV devices, but is not supported on all mobile devices.
You can test for support at run time using the NetworkInfo.isSupported property. See
AIR Profile Support for more information regarding API support across multiple profiles.
The NetworkInfo object is a singleton. To get the single NetworkInfo object,
use the static NetworkInfo.networkInfo property. Do not call the class
constructor, new NetworkInfo().
Most computers have one or more interfaces, such as a wired and a wireless network interface. Additional interfaces such as VPN, loopback, or virtual interfaces can also be present.
A NetworkInfo object dispatches a change event when the available
interfaces change. Call the findInterfaces()
method to determine the most current network information.
Note: The NativeApplication object also dispatches network change events.
