This seems to me to be rather weird: that for the sake of completeness
and consistency you're considering to give an object which (allegedly)
has no notion of "broadcast address" a broadcast address method.
If so, I can see three options. Given an appropriate IPv6 object:
obj.broadcast() always returns None.
obj.broadcast() always raises an exception.
obj.broadcast() always returns something which is not a broadcast
I would hope the third option isn't being seriously considered! Are
there any reasons to consider the first two?
