I think you are saying your ISP isn't providing IPv6 support at all and
that you'd like to totally disable IPv6. If that is the case then you
can do this by adding ipv6.disable=1 to the kernel boot parameters in grub.
If I misunderstood your question let me know and I'll try again after

I decided to do a test and add ipv6.disable=1 to the kernel parameter on
one of my VM's. In the past, this was sufficient. However, doing only
this now results in selinux errors. To avoid those you also need to add
"net.ipv6.conf.all.disable_ipv6 = 1" to /etc/sysctl.conf.
was correct Ed. I meant to say that my ISP doesn't
support IPv6 at all.
Instead of setting the IPv6 options to 'Ignore' in the networkmanager
definition for my router, I have set the option to 'Link-local', which
has also stopped the boot time messages. What exactly does 'Link-local'
actually do (my assumption was it has activated IPv6 addressing for
local network routing but not activated IPv6 for internet routing)?
