To me it makes no sense to "specify a network not just by its network
address", because by definition a prefix + mask is all that
characterizes a network: that's all you need to specify it entirely. 
Adding a "base address" would be like adding a "port number" attribute
to the Address class: it's abusing an existing class by adding
irrelevant information.

I may be mistaken, but it seems to me that, in the IP world, nowhere
does such a "network + host" hybrid appear. You find networks (prefix +
mask) in routing protocols, and host addresses in applicative protocols.
