How disable IPv6?
=================
Debian kernel 2.6/Ubuntu ("official" method)/Fedora Core.
---------------------------------------------------------
Comment in /etc/modprobe.d/aliases "alias net-pf-10 ipv6" and add alias
"net-pf-10 off", "alias ipv6 off"::
$ sudo emacs /etc/modprobe.d/aliases
...
$ cat /etc/modprobe.d/aliases
...
# alias net-pf-10 ipv6
alias net-pf-10 off
alias ipv6 off
...
Reboot or::
$ sudo update-modules
Another way is adding to /etc/modprobe.d/blacklist.local lines::
blacklist ipv6
You can safely wipe out any IPv6 reference in ``/etc/hosts`` and
``/etc/network/interfaces``.

As for Debian, but ``/etc/modprobe.d/aliases`` has name ``/etc/modprobe.conf``.
