Ok. Youngin’ (and cochair of Sunset4) speaking. My experience with
networking begins after these transitions were largely complete, so I
genuinely don’t have a good sense for what was done to “survive" this
transition, and I’d bet Simon doesn’t either. If that’s really the right
model, please explain what that actually means, since in Sunset4 we’re
supposed to be figuring out what this transition looks like, how to turn
off IPv4, etc. If it’s really been done, I don’t want to reinvent the
wheel, but I need more to go on than the handwaving that has so far
accompanied this assertion. Answer specifically if you are thinking of a
specific network, or generically if that’s more appropriate.

Did they die of natural causes I.e. most clients simply stopped having
them enabled by default? If yes, over what timeframe?
Were some networks forcing those protocols to be disabled via going to
each host and manually configuring? Or was the background traffic so
negligible that it was simply ignored?
What was the order of magnitude of size of the broadcast domain? Number of
hosts that might have to be touched on an average network? How many hosts
were dynamically configured vs static? DHCP was pretty new then, wasn’t it?
Since we’ve brought up reducing junk client-sourced traffic on wireless
networks as one of the goals of being able to tell clients to stop
speaking DHCPv4, or IPv4/arp in general, how many wireless IPX and
Appletalk networks were there? (and yes that last question is mostly
tongue-in-cheek)

Thanks,

Wes
