I think LISP is an important factor in the future of Internet and I do
support the idea of having different IP block for LISP based network.

However, I can not support the publication of this document, it has
some unclear issues that need good answers first.



Anyhow, I see two issues that need to be addressed better

1.) How should the address space be administrated, RIR structure or
something else closer to 6bone? I support the suggested idea of
discussing this part with the different RIRs to look more into how
this are going to work in practice.
And as Dino said, "No, I am not making any assumptions either way. How
allocation gets done is subject to more work." the document should
state this.




2.) The interaction between none-LISP and LISP Internet. This problem
has two sub-problems within it

a.) Why is there a need for a special LISP block. This is partly
answered in section 3.  Rationale and Intent. Is this the entire
reason?

<start copy'n'paste>
   With the current specifications, if an ITR is sending to all types of
   destinations (i.e., non-LISP destinations, LISP destinations not in
   the IPv6 EID Block, and LISP destinations in the IPv6 EID Block) the
   only way to understand whether or not to encapsulate the traffic is
   to perform a cache lookup and, in case of cache-miss, send a Map-
   Request to the mapping system.  In the meanwhile, packets can be
   dropped.
<end copy'n'paste>



b.) the routing integration between none-LISP and LISP internet, how
are that going to work?
The current document isn't clear enough on that as I see it. Are there
an assumption that some ISPs will announce the entire LISP space (/16
are mention) for free ?
If each and every EID space holder (/32 or similiar) each have to
connect to Internet and get their address space routed, then it's
nothing different than regular RIR allocated /32's.



Address these thing somehow in the document, even just mention that
it's subject for other document and I'm happy... :-)
