But I am still getting a global IPv6 (and of course local scope).

What else do I need to do to disable the listening for RA announcements

and setting an IPv6 global address?  I do not want to reboot the box.
There are other modules, most notably bonding that rely on the ipv6 module being loaded. What I do is place "options ipv6 disable=1" in "/etc/modprobe.d/ipv6.conf". That does require a reboot, which I know you are looking to avoid, so you may want to try other methods to remove your address in the running configuration.

'All' I need is for the system not to have a global IPv6 address. Then it will not try to connect to other global IPv6 systems which will reject the connection, as the IPv6 rDNS cannot be set, given it is a dynamic IPv6 assigned address from the ISP.

I tried:

# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=z9m9z.htt-consult.com
NETWORKING_IPV6=no
IPV6INIT=no


and 'service network restart' but still showing IPv6 addressing.
