System 2.0.0.0 4.0.0.0 System.Object

The class provides address change notification by raising events. An interface address can change for many reasons, such as a disconnected network cable, moving out of range of a wireless Local Area Network, or hardware failure.

To receive notification, you must identify your application's event handlers, which are one or more methods that perform your application-specific tasks each time the event is raised. To have a object call your event-handling methods when a event occurs, you must associate the methods with a delegate, and add this delegate to the event.

Allows applications to receive notification when the Internet Protocol (IP) address of a network interface, also called a network card or adapter, changes.
