Disabling IPv4
...ave stray IPv4 functions
messing with me.
So in /etc/sysconfig/network, I commented out NETWORKING=yes. I have
NETWORKING_IPV6=yes.
In /etc/sysconfig/network-scripts I altered ifcfg-eth0, setting
BOOTPROTO=none. That was enough for eth0 to only have IPv6 working on
it (have IPV6INIT=yes and IPV6_AUTOCONF=yes).
But lo had IPv4. So I commented out all of the IPV4 lines in ifcfg-lo.
Still have IPv4 on lo. How do I disable that?
Yes, I did an service network restart after changing ifcfg-lo.

Disabling IPv6 Auto Configuration
I am using stateless auto configuration for most of my clients. For
the servers I prefer to manually assign the address. I have defined
the IPv6 address in the ifcfg-eth0 file and set IPV6_AUTOCONF=no.
However ifconfig shows both the auto configured and manually assigned
address.
Looking around I found that net.ipv6.conf.default.accept_ra is set to
1 by default. The ifup-ipv6 is setting net.ipv6.conf.eth0.accept_ra to
0 like it should. From what I can tell the auto configuration is
happening...

function/notation to calculate those auto-configured addresses for the user,
so we can write something like this:

<ipv6 srcipaddr='ipv6_autoconf($IPV6_PREFIX[@1], $IPV6_MASK[@1], $MAC)'/>
</rule>
<rule action='return' direction='out' priority='500'>
<ipv6 srcipaddr='$IPV6'/>
