Re: [Int-area] practical issues with using v4-mapped addresses for nat64

[Jari Arkko <jari.arkko at piuha.net>]

Marcelo, Iljitsch, what was the method you used to "disable v4"?

I agree with Dave that an important scenario to consider for this 
particular functionality is a host without any v4 stack; but since there 
aren't many of those its going to be hard to test this. In some sense we 
can rely on future implementors to do the right thing, particularly if 
we publish documents saying what the right thing is.

However, another important scenario that I would like to test is having 
a normal host (say, Vista or Linux) that can support both versions, and 
then running that in a network that has no IPv4. That is, DHCPv4 does 
not respond, routers do not route IPv4 packets, etc. (The host might 
come up with some link local addresses, however.) In that environment, 
what happens? If typical implementations fail in some manner in this 
scenario, it means that the NAT-PT replacement is going to have a hard 
time in any network except those involving purpose built new hosts...
