Re: Mass ipv6 lookups
Clarification.
I have 40+ servers. I have thousands of users (university of 45000
students, and 10000 staff). Our mail servers complete over 18 million DNS
lookups a day. That is now almost doubled with the AAAA lookups. So no,
I don't think my DNS servers can handle such a drastic load change.
