Examples of java.net.NetworkInterface

java.net.NetworkInterface
This class represents a Network Interface made up of a name, and a list of IP addresses assigned to this interface. It is used to identify the local interface on which a multicast group is joined. Interfaces are normally known by names such as "le0". @since 1.4
