Will split the patches.

that maybe then you wouldn't need the extra copy constructor? This class is constant, i.e.,
you never manipulate `address_` or `netmask_`, but actually making this `std::shared_ptr<const
IP>` might be just as tricky. Either way, comment on why this has to be a pointer!

Valid point. Will add the comment.

About `std::unique_ptr` vs `std::shared_ptr`, the argument is valid (not requiring the copy
constructor) and I was thinking about it as well. The problem I had was that semantically
it seemed incorrect (in my opnion). Each `IP::Network` is an individual object that does not
share state with another copy so thought `std::unique_ptr` better exemplifies this semantic.
But I also agree that this is an implementation detail and the object itself is a ready only
(we do not allow manipulation of the `address_` and `netmask_` properties). Will defer to
your judgement on the use of either.
