Email over v6

Thu Jul 8 21:13:41 UTC 2010

A few people have sent private replies commenting on the email/IPv6 deployment stats I posted.

I thought I would also share some nameserver statistics to give an idea of what I see (at least at puck.nether.net) for IPv6 vs IPv4 queries.

I won't break down the numbers for everyone, just posting the raw values from a bind stats dump.

The stats are from ~June 21st to now.
