Just to be sure we are saying the same things, I am saying that the programmer should be getting the interfaces for the network and walking them looking for the interface with the address they are interested in, and getting the IPMask for that interface. Alas, this is harder than it might be, you have to use a type switch to get the mask since what the net.Interfaces() gives you is a *net.Addr while the mask is part of the implementation, *net.IPNet. As it stands, a new programmer might think DefaultMask() is what should be called.
