That said, /48 to the home should be what is happening, and /56 is a better compromise than anything smaller.
Is hierarchical routing within the SOHO network the reason you believe /48 is useful? You don't really imagine that end-users will require more than 2^8 subnets, but that they will want several levels of very simple, nibble-aligned routers within their network? This is perhaps a good discussion to have. I, for one, see CPE vendors still shipping products without IPv6 support at all, let alone any mechanism for creating an address or routing hierarchy within the home without the end-user configuring it himself. I am not aware of any automatic means to do this, or even any working group trying to produce that feature. Is it true that there is no existing work on this? If that is the case, why would we not try to steer any such future work in such a way that it can manage to do what the end-user wants without requiring a /48 in their home? -- Jeff S Wheeler <jsw@inconcepts.biz> Sr Network Operator / Innovative Network Concepts
