I can see cases where the caller must do calculations for 'from & number'
and not for 'first & last' (quickly, how many K is there from
C0000-C5FFF?). It all depends on how the range is originally given.
Since we all prefer 'first & last' for the final presentation to the user,
it seems that 'first & last' is the more intuitive of the two, so I would
say it is better for requesting as well.
