That's very poor practice. Each announcements costs *other people* the better part of $10k per year.
That sounds ... really really big to me, Bill. Do you have a source for that cust-accounting number?
Hi Jay, The "better part" of $10k. It's been several years since I refreshed the source numbers but the formula for the estimate and what were then the source numbers are documented at http://bill.herrin.us/network/bgpcost.html Also note that was for IPv4 announcements. I didn't cost IPv6 announcements but it looked like they were roughly twice the price. That may or may not still be true depending on how the switching engines are built these days. My guess is: no change. And yes, it is a really big number. At the time it meant that roughly $2B of the annual worldwide economy (something like 2/1000ths of a percent) was attributable to the BGP prefix count. Regards, Bill Herrin -- William D.
