I think the answer very much depends on who you ask.
with my researcher hat on, i am curious yellow. with a minor concern for how much of the lab's resources it would consume. with my operator hat on, kinda meh. the long tail of recalcitrant devices is likely to be far too operationally painful. but truth is, i do not know the size or length of that tail. which tweaks my researcher hat. so i would be interested in learning the details of an experimental design to tease out where the problems would be. seems like the kind of engineering an rir should be doing.
Those that have beein doing IPv6 since ages would claim that any time spent on "making formerly-reserved IPv4 addresses usable world-wide" is energy lost on making IPv4 go away instead... so, "no".
ahhhh, religion. robert and crew, can we do zealotry measurements with atlas probes? :)
have you enabled IPv6 on something today...?
not for years. randy
