I've read the documents (except the IPv4-specific ones) and I believe
they are mostly complete and clearly explain how ILNP works.

There is just one thing which seems to be absent: I do not find
clearly stated how are the identifier and locator stored in the IPv6
packet. From some paragraphs, I guess the locator use the high-order
64 bits of the IPv6 address and the identifier the low-order bits but
I was not able to find it clearly written.

Another point is more a detail: the documents seem to mandate that
there is a state in the machine for every ILNP correspondent (the
ILCC). This is no problem for a HTTP server (there is already the TCP
state) but more problematic for active authoritative DNS servers:
today, they are able to sustain a very high activity because they have
absolutely zero state. May be the ILCC could be made optional for
stateless servers? (There is no need to receive locator updates for
the ultra-short transactions of the DNS.)

Otherwise, there is a typo in the references,
draft-irtf-rrg-ilnp-noncev6 is written draft-irtf-rrg-ilnp-nonce6 in
the docs (no 'v').
