Hey Antoine,

Can we drop the pedantic discussion about what "should" or "shouldn't"
be the job of a "Network" class, and just proceed to a pragmatic
compromise? Peter has already posted that he is okay with __eq__ and
friends ignoring the .ip attribute, which sounds good enough to me.
His use case (which he mentioned to me off-list) is simply that if the
denormalized .ip attribute weren't saved as part of the IPNetwork
class, in many cases he'd have to keep track of it separately, which
just feels clumsy.
