This class represents a network interface.

NetworkInterface is used with MulticastSocket to specify multicast interfaces for sending and receiving multicast messages.

The class also provides static member functions for enumerating or searching network interfaces and their respective configuration values.

On Windows, detection capabilities vary depending on the OS version/service pack. Although the best effort is made not to attempt access to non-existent features through a combination of compile/runtime checks, when running binaries compiled on a newer version of the OS on an older one problems may occur; if possible, it is best to run binaries on the OS version where they were compiled. This particularly applies to OS versions older than Vista and XP.
