Instances of this class represent a network interface on the local machine. getName( ) and getdisplayName( ) return the name of the interface, and getInetAddresses( ) returns a java.util.Enumeration of the internet addresses for the interface. Obtain a NetworkInterface object with one of the static methods defined by this class. getNetworkInterfaces( ) returns an enumeration of all interfaces for the local host. This class is typically only used in advanced networking applications.
