>In the entire Internet, there are only 16,384 /16 ranges (also known as Class B networks), with 65,536 addresses per range. So, if /v/ or /pol/ has 3,000 ranges (active users), that means their posters represent 18% of the possible number of ranges on the Internet. Many ISPs only have one or two ranges.
