I wish there was better public data we could use here to generate these =
numbers.
But there is a dearth of such numbers that are vaguely current =
relatively inclusive
and not completely stupid.
So we use the ad placement mechanism as an indirect pointer to user =
count. Its very rough,
and at best one can say that there are large, medium and small eyeball =
networks, and
to a first order the algorithm appears to identify networks into these =
three categories.
I am not trying to tie in address density here - I=E2=80=99m not even =
sure that would be wise
because, as you well know, NATs hide all kinds of sins and virtues.
