Hi,

I'd like to comment a bit on this patch, too.

I wouldn't call that a "problem", rather a "particular default
behavior", or something along the line.

True, but this is not because of the "automatic" IPv4 IP assignation
counterpart, but rather (to me) because you want IPv6 autoconfiguration
in almost _every_ situation.

For me too. If find that it ties too much dhcp and IPv6
autoconfiguration together. To me, even if both have the same goal, the
reason of their existence is different : DHCP is kind of bad "hack" on a
problem that IPv6 solved more cleanly and that is more "general".

I don't agree. I don't have any particular use case, but wanting a
static IPv4 address doesn't mean to me that i'll also absolutely want a
static IPv6 one. The former case is used more often than the latter, and
there is not always an implication relation between the two.

I don't think so. Furthermore, I don't really like naming IPv6
autoconfiguration "dhcp".

To me, the most interesting "option" is static IPv4 with IPv6
autoconfiguration, which is what is done today by default. (I agree that
in my use case, I generally do DHCP with static leases tied to a
particular MAC, which rather goes in your direction ...)

Maybe I don't have any really convincing argument, but I feel
unconformable tying dhcp and IPv6 autoconfiguration together (and DHCPv6
exists, too ! -- even if I never used it ...) 

My 2 cents ...
