It should be clear that 14% received here is email to RIPE NCC servers. I
don't think we have 14% of SMTP traffic out there coming via IPv6. Actual
SMTP traffic may still be under 1%, I have done some work with a colleague
to sample 0.5M domains yielding in <2% AAAA MX records and we heard similar
data with other folks that ran a similar experiment. Seeing an uptick on
quad A MX record is still a good thing and tells us there is some form of
migration but SMTP over IPv6 will be really valuable data here. Has anyone
collected and published data on this?
