http://www.ripe.net/ripe/docs/charging2004.html As clearly stated in the above URL, RIPEs charging scheme is almost solely based on how many ip addresses you require and it should be fairly easy to calculate the direct cost of a /25 allocation vs a /27. It might not cost that much in RIPE fees for a /25 or /27, but I don't see why an ISP shouldn't be able to charge their customers using the same scheme if they wanted to (and of course also add administrative fees etc).
Having such a cost distribution system would cost more for the ISP than what the gain is. Really. If you can this way optimizae that you're Medium instead of Large, you win 1500 EUR. Such ISPs would have at least 100 customers, I'd guess. So that's likely at maximum 1 EUR/customer/mo. Hardly something what's worth even thinking about in the billing department. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks.
