Add the following line to /etc/modprobe.conf
alias net-pf-10 off

In /etc/modules.conf (depends on your Distro) add
alias net-pf-10 off

and release level, a few releases back and you are correct.
Newest release it can be /etc/modprobe.conf

I always add the line
IPV6INIT=no
to /etc/sysconfig/network-scripts/ifcfg-eth0
[or eth<X>].

Is that sufficient?

Incidentally, isn't it crazy that one has to write
gibberish like "alias net-pf-10 off" ?
What on earth does this mean?

Don't know. That directory doesn't even exist on my (Slackware) system.

Can't recall off the top of my head, but there is a list of a bunch of
these standardized items... Google would find it if you cared.

If your system is encumbered by the hideous mess of dereferenceable
environment variables that is a Red Hat-style /etc/sysconfig/ tree, yes,
that is indeed one different way to accomplish the same thing. Unlike
the other answer cited, it doesn't apply to Linux generally.

It means don't load the net-pf-10 kernel module, which handles ipv6.

If you are on redhat or alike, it doesn't look that bad.

Don't even attempt to load the ipv6 (net-pf-10) module.

If net-pf-10 means "ipv6" why not call it "ipv6".
Or would that make it too easy for Linux users?
Sigh ...

Flexibility might be a reason for the module alias system, so you
can load another module, your own or whatever for some subsystem
if you want? Looks pretty clever to me, "alias ipv6 ipv6" would
look curious and you couldn't tell what the alias name and what
the module name on the first view.

There are a couple of net-pf-[nn] aliases. Unsure why you seem to
dislike the flexibility of the Linux kernel?
