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.
