Suggestion:
* Certain network interfaces, such as the loopback interface, do not
support
* broadcasting and will also return {@code null}.
Maybe the class level API documentation should also be updated something like:
* This class represents a Network Interface address. In short it's an
* IP address, a subnet mask as well as a broadcast address when the address is
* IPv4 and the interface supports broadcasting.
* An IP address and a network prefix length in the case
* of IPv6 address.
It would be good to have @Michael-Mc-Mahon approve the wording.
