"Well, you say we need to spend more money every year on address space.Right... Let's look at this in detail: /48 per customer == 65,536 customers at $2,250 == $0.03433/customer /56 per customer == 16,777,216 customers at $2,250 == $0.00013/customer So, total savings per customer is $0.0342/customer _IF_ you have 16,777,216 customers. On the other hand, sir, for those customers who need more than 256 subnets, we're running the risk of having to assign them multiple noncontiguous prefixes. Although the cost of doing so is not readily apparent, each router has a limit to the number of prefixes that can be contained in the routing table. The cost of upgrading all of our routers later probably far exceeds the $0.03 per customer that we would save. Really, in general, I think that the place to look for per-customer savings opportunities would be in places where we have a potential recovery greater than $0.03 per customer. This discussion is getting really silly; the fact of the matter is thatTrue, but, they don't, generally, charge by the address, either. Usually, they charge by the month. If you can't cover $0.03/year/ customer for address space in your monthly fees, then, raise your monthly fee by $0.05. I'm betting your customers won't care. I'm betting that competition will drive the boundary left without additionalAs an enduser I would love to pay the little fee for IP space that the fees. After all, if you're only willing to dole out /64s and your competitor is handing out /56 for the same price, then all the customers that want multiple subnets are going to go to your competitor. The ones that want /48s will find a competitor that offers that. That's how the real world works. I remember having to repeatedly involve senior management in rejecting requests for /24s from customers who could not justify them because our sales people at Exodus kept promising them. The sales people continuously suggested that our competitors were offering everyone /24s and that they had to do that to win the deals. OTOH, "Raw bandwidth communications" seems to want to charge bandwidth utilization not actually based on the bandwidth utilized, but, the number of IP addresses routed. They are not my ISP for that reason. Different providers have different business models. Consumers will find the provider with the business model that best fits their needs. That's the way it works in the real world. Assuming that PD is available is naive. However, assuming it is not is equally naive. The device must be able to function in both circumstances if possible, or, should handle the case where it can't function in a graceful and informative manner. Owen
