Thank you, but unfortunately this is a different issue. These boxes do not run bind, they resolve their DNS queries via dedicated bind servers on the network. Configuring the bind servers on the network a different way still would not stop the IPv6 traffic I am showing in the TCP dump from being sent.
Things described in the bug report are
Adding NETWORKING_IPV6=yes to /etc/sysconfig/network prevents the queries to root nameservers with IPv6 addresses timing out.
And
alias net-pf-10 off to /etc/modprobe.conf
Have you tried both of them?
