Ah. *This* is where you fell off the horse.
Nope; the first one isn't smooth; it's *completely arbitrary*.
The mapping is, in fact, DNS's raison d'etre.
The second one has a relatively smooth mapping *at any given point in time*,
but you can't fit a function to that; it is prone also to arbitrary changes
over time.
