So in effect we've gotten ourselves in a situation where IP
addresses are too topology-independent to provide good scalability,
but too topology-dependent to provide real location-independence at
least for individual devices, because of equally strong forces
pulling the IP assignment process in both directions at once. Hence
the reason we desperately need locator/identity separation: so that
"locators" can be assigned topologically so as to make routing
scalable without having to cater to conflicting concerns about
stability or location-independence, and so that "identifiers" can be
stable and location-independent without having to cater to
conflicting concerns about routing efficiency.
As far as specific forms these "locators" or "identifiers" should
take, or specific routing protocols for the "locator" layer, or
specific resolution or overlay routing protocols for the "identity"
layer, I think there are a lot of pretty reasonable options; my
paper suggested one, but there are others.

thanks brian for your great explanation , something came to my mind
imediatly,
.........i remember these days when i connect to the internet using my
1 und 1 - 14,4kb modem in the 90th
there was no NAT,
i connected with a little programm to a specific ip adress,
there was not even DNS involed at that time. for the programm i was
talking about ;)
So there were no caches und buffers with information about my usage
exept on the server where i was connected to.
Just one question because i am reading a lot about all these routing
ptotocols in the past , is uia / uip more usefull in sparse or dense
networks or both ?
bright new 2009
cheers from cologne

i believe that "Kademlia " [ 1 ] for example and the
technologies
mentioned in the linked paper [ 2 ]
would fit the needs and requirements for a future proof internet.
