I guess we would indeed see notable increase in traffic if we enabled the IPv6
also for other than 2.* names.
Btw. Why is pool still in this old “only minorities are offered IPv6”-thinking?
Nowadays all even close modern Linux distributions along with W7, W8 and OS X
are pretty well configured and protected, even for case of non-functional IPv6
network. And AAAA records have been there for ages, so if some vendor hasn’t
really ignored them if necessary, it would be really weird. Not to forget that
for many of the clients failing NTP-query is by no means fatal. Unless there is
some ntpd server side reason I’m having hard time understanding current
configuration.
If it was up to me, I would maximum go and leave some legacy name for people
who get itchy or have some exotic equipment for the IPv6. Probably I would just
enable it for all, even more complex wide spread services (some even
commercial!) have now v6 on by default.

I started making a program to track the NTP traffic last fall, but I didn't get
too far.
I'd guess 1/50 to 1/200th of the IPv4 traffic.

Some years ago I made a javascript widget to test how many end-users had IPv6
support (the widget is on the NTP Pool site and a few other sites I'm involved
with); it says adaptation is up to about 4%.

For servers it's probably a bit more, but on the small appliances and such that
use the NTP Pool it's probably lower, so as a ballpark estimate we can go with
4% on the high side. Google says it's much lower:
http://www.google.com/ipv6/statistics.html
Currently only people asking for 2.* (2.pool.ntp.org, 2.fedora.pool.ntp.org,
etc) even has the option of getting an AAAA record, so that probably makes it
down to 1/3 to 1/6th of the regular traffic, too.
