I haven't seen that work, but I am guessing this number is an
aggregate (i.e. every cost to everyone on the 'Net combined), not per-
network? See, I'm just looking at that TWO BILLION DOLLARS PER YEAR
number and thinking to myself, "um, yeah, right". :)
So, given that there are 27206 ASes in the table (latest CIDR report),
that means it costs each AS, on average, less than $0.30/year to
accept a prefix. I'm thinking that billing each new network with its
own prefix would cost more than $0.30/recipient.
Let's make it easy. Let's say only 8K ASNs actually take a full
table. (Rest have partial tables or two defaults or something.) So
each network needs $1/year per prefix. I still think the billing
infrastructure would cost more than the bill itself.
But then, the telcos have been in that situation for a century. Why
shouldn't the Internet follow in their footsteps?
Feel free to explain how confused I am. (But be warned, I am not
going to believe it costs $2B/year to run a multi-homed network with
two full feeds. :)
