Disable Ipv6 – Ferhat Elmas

How to disable IPv6?

To check status:

cat /proc/sys/net/ipv6/conf/all/disable_ipv6
0

Zero means it's enabled, proceed.

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1

Edit /etc/default/grub such that:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ipv6.disable=1"
GRUB_CMDLINE_LINUX="ipv6.disable=1"

and then run sudo update-grub.
