I have to disagree on that. NATs is the problem and I am one of the
causes of that problem as one of the principals behind RFC 1918.
What has happened is that HTTP has become the transport for the
Internet. Very bad in a number of ways.
But for another time. Perhaps. Right now I have to deal with a new ISP
that was on the road to static IPv6 when somehow the lead engineer kind
of stopped responding to emails and I won't find out the details until
IETF later this month.

Subject: Re: Centos 6 - disabling IPv6 addressing
Sorry - that should be
sysctl -w net.ipv6.conf.all.accept_ra=0
to disable that, not 1.

Try:
sysctl -w net.ipv6.conf.all.accept_ra=1
to persist between boots, be sure to add this to your /etc/sysctl.conf
file.
This should prevent the box from listening to any RA announcements.

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.
I would try adding the below line to /etc/sysconfig/network.
IPV6_AUTOCONF=no
