I thought I'd done that standard stuff /etc/modprobe.conf: alias net-pf-10 off alias ipv6 off /etc/sysconfig/network: NETWORKING_IPV6=no
But on reboot I still see ipv6 entries against the eth devices, ipv6 module is still loaded, and sit0 tunnel is present.
What needs to be done to disable ipv6?

I had this exact same issue on one of my machines, and I found out that the "openib" (InfiniBand) package was installed and enabled, although not needed. The InfiniBand modules were loading the ipv6 module as a dependency, that way it was being indirectly activated. After uninstalling the RPM and rebooting the machine, it no longer has IPv6 active.
If that is not the specific case with you, see in the output of "lsmod" if ipv6 is being used by another module, if that is the case, you can try to see who is pulling that module and try to desactivate that one.
HTH, Filipe

Just put these in your /etc/modprobe.conf to disable IPv6:
blacklist net-pf-10 blacklist ipv6 install ipv6 /bin/true

Hmm, well Filipe's answer also worked (openib package for InfiniBand was causing ipv6 to load as a dependency).
I guess your answer works by forcably failing any attempt to load it, even as a dependency.
Thanks to you both.
