Those type of access noted in the slides should be (from the implementations point of view) possible with private/NAT IP space, too. Thus you cannot justify a possible future IP demand with a false implementation of services.
Just to make sure this is clear: current policy does NOT force NAT and private space on anyone. It is made sure that requestors have thought about private address space and then decided to apply for public IP space, but no pressure is applied(!). There are lots of applications that do not work properly with NAT (most kind of "incoming multimedia apps", like CuSeeMee, Netmeeting, etc.) and those will gain in popularity in the years to come. So while NAT will work for some, it is not a solution for everybody.
There might be other justifications, but widely deployed Internet TV and VoIP which is designed to need non-private IP space at the customers side is the proof for that something is wrong with the implementation of Internet TV and VoIP.
No - it just shows that the IETF is right with their belief that "NAT is evil" (not all IETF activists, but many).
This is simply a mathematical fact as there are less IPs (4 Billion) than possible customers (5 Billion, and for VoIP plus Internet-TV you then need 10 Billion IPs).
Yes. This is why we should go to IPv6 as quickly as possible. Gert Doering -- NetMaster -- SpaceNet AG Mail: netmaster@Space.Net Joseph-Dollinger-Bogen 14 Tel : +49-89-32356-0 80807 Muenchen Fax : +49-89-32356-299
