Return values

This module will return NaN in the case of a badly-formatted IP, or a number in the case of a non-valid but correctly-formatted IP.

The reasoning for returning NaN is thus: we're converting to a number, so we're expecting to do some sort of comparison with it - which will always fail in the case of NaN being compared. Secondly, an IP is a representation of a number - if the format is incorrect then it is technically not a number and thus NaN is correct.

The reasoning for not checking the validity of an IP is mostly practical - this module is a single-concern module. Checking the validity of an IP should be done in a separate module, as that requires it be explicitly included (sometimes, we may either trust the original source of the data, or simply not care).
