+
−
+
−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 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".
