> We have specified an Internet that works, at the network layer,
> using relatively stable but not permanent identifiers for connection
> endpoints, which are allocated and administered using a topology
> dependent model, implying a service provider dependent model.
> 
> But we run into problems (the architecture doesn't quite fit) when
> we try to address some scenarios encountered in real life:
> 
> . multihoming
> . assembling a local network without necessarily having to contact an ISP to obtain address space(e.g.,home net)
> . renumbering local networks without significant pain
> . working with wireless networks, where the concept of "link" can be quite fuzzy
> 
> Some proposed solutions are challenged in terms of:
> 
> . providing referential integrity - how is referential
> integrity maintained when identifiers are not globally
> unique or are overloaded?
> . choosing between different identifiers for an object which
> has different "reachability" and the reachability is
> context-dependent
> . security/transiting trust in layered address
> resolution . providing solutions that work across all layers of
> the stack and all areas - how do we find a solution
> that is great for routing but also great for security?
> 
> The purpose of this mailing list is to identify and clarify the types of

> to debate the merits of approaches that:
> 
> . provide scoping at the IP layer
> . provide scoping at some other (single) layer
> . provide new addressing paradigms that span several layers

> illustrations for discussing problem types, and merits of
