At some point you won't have a choice, but until then, there are ways
to prevent IPv6 configuration on an interface. Edit the ifcfg-ethX
file and add:
IPV6INIT=no
If you are using NetworkManager, you may want to edit /etc/sysctl.conf
and add these lines:
net.ipv6.conf.ethX.accept_ra = 0
net.ipv6.conf.ethX.accept_redirects = 0
net.ipv6.conf.ethX.autoconf = 0
For each of your ethernet devices.
We have removed the ability to disable loading the ipv6.ko kernel
module.
