$ sudo echo 1 >Â /proc/sys/net/ipv6/conf/all/disable_ipv6
But if you want it perm set
$ sudo vi /etc/sysctl.conf
append…
net.ipv6.conf.all.disable_ipv6 = 1
Seems even after doing this on my Fedora box, that didn’t work either…it was still sending DNS aaaa traffic out. Â Added this and rebooted..and this seems like it fixed it
$ sudo touch /etc/modprobe.d/disable-ipv6
$ sudo echo “options ipv6 disable=1” >> /etc/modprobe.d/disable-ipv6
Another possible way,
$ sudo vi /etc/default/grub
GRUB_CMDLINE_LINUX=”ipv6.disable=1 rd.lvm.lv=fedora/swap rd.md=0…..
$ sudo reload
$ sudo grub2-mkconfig-o /boot/grub2/grub.cfg
$ sudo reboot
And even yet another possible way…
$ sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
$ sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
