It seems you are uselessly conflating two perfectly distinct concepts: Address and Network. You also haven't addresses the issue of comparing together (and hashing) two addresses with the same IP but pointing to a different network. No answer to this issue seems satisfactory and obviously right. As it is, -1 from me. Either we only keep two concepts (Address and Network), or if we introduce a third one (AddressWithMask, whatever) for added practicality; but we shouldn't blur the line between the two former canonical concepts under the pretext that a platypus-like Address might be helpful in some particular situations.
