If such a company exists, and had such an incredibly popular web site, I wouldn't worry too much. I suspect the major NSP's would engage in several creative routing configurations (short-circuits, backdoors, etc). If only in an attempt at self-preservation to keep the NSP's backbone interconnects (and customer service phone lines) from melting down. Much like a radio station with a single telephone contest line can bring down an entire city's telephone system. I'd bet even Mr. Doran (or Mr. Doran's managers) would make an exception given the right economic incentives. BTW, my definition of a "very, very, very popular web site" requires multiple DS-3's (or whatever the backbone du jure is using) to support the bandwidth needs. A site at the end of a 56K line isn't going to be very, very, very popular for very, very, very long.
Consider a company, perhaps a very, very, small company, which happens to have a very, very, very popular web site. For the sake of argument, let's call this company "Netscape," (although this company isn't Netscape, but this will create the appropriate picture in your mind).
This company needs only a microscopic amount of address space, something on the order of a /28.
The company wishes to have more than one connection to the Internet through more than one of the major providers, for bandwidth & reliability reasons.
It sounds to me, based on the discussions which have been occurring, that this company can't do what they want---unless they lie and somehow gobble up a /18 worth of address space.
Is this true?
