Speaking purely as a DHCPv6 software implementor, and an IPv6 operator
you would no doubt believe to be of very little significance, I can
say that Alain Durand is not the only operator who has requested this
DHCPv6 software feature.  It is quite a staggering number of operators
who would prefer to run their networks in this way (or rather, who
would prefer not to operate with RA), ranging from large to small.  I
can, but will not, name them.  I do not think they signed up either
for me to speak as their proxy, nor for them to be interrogated by
you.  They have day jobs.


I think it is interesting that someone (was it David Thaler?) said at
the microphone in INTAREA that "If it is the case that DHCPv6 must
have feature parity with DHCPv4, then these options do not complete
that requirement."  I thought this was very insightful, and wholly
true.

I have information that other drafts are forthcoming.  I think we are
going to see a wave of work due to these operators that wish for IPv6
to be an equal-penalty upgrade, and not "lose features" by it.  Said
another way, it does not matter if IPv6 sucks equally to IPv4 (from
their own personal point of view about how networks should be built),
or has no compelling feature outside of address space to justify
itself, it merely must not suck worse.

We are going to see more efforts to make IPv6 "suck the same."

I believe this discussion is reasonably fully, and appropriately
provided in the draft's Introduction, and has been presented in full
during the int-area (and I presume shortly the rtg-area) meeting.  I
do not think we will gain anything through repetition of it.

Nothing has changed.  You could say that the IETF's collective answer
that the customers' requirements are insufficient justification has
been rejected by the customers.  I see no reason why that will change
either.

On this issue, I will defer to the customers' requirements and reject
the collective's vision to change them.

You are free to make your own determination.
