to Margaret for comment. She might tell me to scrap it - it's a big
change from draft-mrw-nat66-00. However, I'd appreciate comments on
it from this list.
Fred,
we certainly carefully review this. This seems to be what we call for
for years and documented for an ITU /3 block in 2005. This way the
local part of the address we call IDv6 is uncoupled from IPv6 by a
function. This brings stability to both side and certainly go with
the IUI (Intelligent/Internet Use Interface) concept derived from
IDNA2008 consensus.
Thanks

The big changes are:
- Change the acronym "NAT66" to "NPTv6", so people don't read
"NAT" and MEGO.
- Change the term used to refer to the function from "NAT66
device" to "NPTv6 Translator". It's not a "device" function,
it's a function that is applied between two interfaces. Consider
a router with two upstreams and two legs in the local network;
it will not translate between the local legs, but will translate
to and from each upstream, and be configured differently for
each of the two ISPs.
- Comment specifically on the security aspects.
- Comment specifically on the application issues raised on this
list.
- Comment specifically on multihoming, load-sharing, and asymmetric
routing.
- Spell out the hairpinning requirement and its implications.
- Spell out the service provider side of Address Independence;
-00 focuses on the edge's view
- Detail the algorithm in a manner clearer to the implementor
(I think)
- Spell out the case for GSE-style DMZs between the edge and the
transit network, which is about the implications for the global
routing table.
