Seems like this isn't such a flexible way to store them (other than as a
string, I guess). It's rare that you'd care about particular octets
on their own. An IP address is just a 32-bit number, and the easiest way
to work with numbers is in their native form. Imagine if you had a bunch
of 5-digit numbers you were working with; would you create 5 fields in the
database, each to store one digit?
