My understanding was that the traffic is not charged to the IP but to
the physical line and that line happens to have a static IP. There is only
a subtle difference but it means that it does not matter who the Internet
user is, or if they have ever connected to the internet using that ADSL
line or not. It only matters what IP is assigned to that physical line and
who rents that physical line.

In theory I think that it is possible to get gigs of data on a line before
any one connects to it. If the IP gets a DoS attack just after the line
is installed then the line renter would pay for that data.
