Well, let's try to turn the problem on its head and see if thats clearer; Imagine an internet where only your closest neighbors know you exist. The rest of the internet knows nothing about you, except there are mechanisms that let them "track you down" when necessary. That is very different from today's full-routing-table.
Yes, it's true that it's different, but is it better?
Well, the reason for people wanting to stick to their "own" IP adresses are administrative and technical. If we solve that then hopefully, it wont be such a big hassle to renumber to go to another provider.It does not provide 100% provider-indepence to begin with. Depending on who you ask that alone is a show-stopper.
Also, if everybody got their equal size subnet delegation from each ISP then it shouldnt be that much of a problem to run two "networks" side-by-side by using the subnet part of the delegation equal to both networks, but keep the prefix separate. If you switch providers you change the prefix part. This means we need new mechanisms to handle this, but I feel that's better than doing the routing mistake again.
So what is it you're proposing? I understand what shim6 tries to do (since it basically keeps most of todays mechanisms) but I do not understand your proposal. Could you please elaborate?The internet shouldn't need to know anything about individual users to begin with, provided there are mechanisms avilable track them down. By that I mean that algorithms to locate end-nodes may include mechanisms to "interrogate" a large number of nodes to find the desired location as opposed to looking it up in a locally stored database (routing-table).
Should end users really care for that level of routing information?I thought DNS only provided a name for an address ;) How does DNS tell us that e.g. 126.96.36.199 is part of a subnet belonging to AS2838 and how to get there?
Also, your proposal seems to indicate that we need something that sounds like a proxy server that actually do know more about the internet and who needs to keep state, this doesn't sound scalable?
