public class QNetworkInterface
The QNetworkInterface class provides a listing of the host's IP addresses and network interfaces. QNetworkInterface represents one network interface attached to the host where the program is being run. Each network interface may contain zero or more IP addresses, each of which is optionally associated with a netmask and/or a broadcast address. The list of such trios can be obtained with addressEntries()
. Alternatively, when the netmask or the broadcast addresses aren't necessary, use the allAddresses()
convenience function to obtain just the IP addresses.
QNetworkInterface also reports the interface's hardware address with hardwareAddress()
.
Not all operating systems support reporting all features. Only the IPv4 addresses are guaranteed to be listed by this class in all platforms. In particular, IPv6 address listing is only supported on Windows XP and more recent versions, Linux, MacOS X and the BSDs.

public final java.util.List addressEntries()
If the netmask or broadcast address information is not necessary, you can call the allAddresses()
function to obtain just the IP addresses.
public final QNetworkInterface.InterfaceFlags flags()
public final java.lang.String hardwareAddress()
Other interface types may have other types of hardware addresses. Implementations should not depend on this function returning a valid MAC address.
