The InterNIC and the other "network engineering" bodies may not have taken this into account. The story goes like this... ISP X is bidding on an important account with Company Y...there might be 16 other companies bidding for the same account...ISP X has a strong relationship with one or more large "upstream providers" that also happen to sell long distance telephone service... It might happen that Company Y "dislikes" the upstream provider because of a variety of reasons...maybe Company Y is owned by another similar company... maybe a competitor of the upstream provider employs several thousand people in the area and the upstream provider is not welcome in the area...maybe the upstream provider filed suit against a local university over an operating system and the people have never forgotten this... ...the point is that the InterNIC can not have a full understanding of the local and global politics that can determine which way these decisions are made... By "coaxing" ISPs to their upstream providers and not providing them with portable globally routable IP addresses, the InterNIC could be setting an ISP up for failure...the InterNIC and IANA are not taking into account the business realities of the world... ...furthermore, by providing "selected" ISPs with portable, and globally routable IP addresses, the InterNIC and IANA are making it easier for some companies to "win" bids like the one described above...ISP X may not have a chance because they can not offer the same "independence" from a particular upstream provider that might be desired by Company Y...because of historical reasons which are not discussed... -- Jim Fleming UNETY Systems, Inc.
