Method 1, add the line:
alias net-pf-10 off

This is the right way to do it.
Method 2 Add to /etc/sysconfig/network file:
NOZEROCONF=yes # Bonus: Disable the ugly generation of 169.254
zeroconf networks.
NETWORKING_IPV6=no
However adding the NETWORKING_IPV6=NO has no effect whatsoever because
even after a reboot the interfaces continue to load an ipv6 address. BTW
it does the same for zeroconf and doesn`t work either.
It doesn't work on its own since as soon as first IPv6-capable daemon
(for example sshd) attempts to bind to the ports, the ipv6 kernel module
gets loaded and it will assign all interfaces default link local
addresses to all interfaces.
However, do note that apart from deleting ipv6.ko from the disk, there's
no good way to get rid of IPv6 for sure. Even with the both of the
above, if somebody/something does "modprobe ipv6", the module gets
loaded and it does its thing with link local addresses. Once it is
loaded it is next to impossible to unload it from the running system.
