To be honest, given the indexing behaviour, I'm -1 on the idea of giving the network address or broadcast address attribute names at all. Consider:
networkaddress = mynet[0] broadcastaddress = mynet[-1]
My only concern with this is a possible performance issue with v6 networks. Would this be implemented such that [-1] doesn't need to iterate through the (possibly large) address space of a v6 network?
I think it could (and would) be implemented efficiently, so I'm +1 on not giving these names, but adding this "recipe" to the documentation instead.
