Description

Correctly the properties of `net::IP` are `private` making it hard for classes to inherit `net::IP`. Although `net::IPv4` and `net::IPv6` already inherit `net::IP` they don't have access to the storage structures stored within `net::IP`. While this works for the current API this is not very extensible.

Hence, we should make the properties of `net::IP` protected instead of private.
