To temporarily disable IPv6 address on Ubuntu 20.04 LTS Focal Fossa execute the following commands:
- sysctl -w net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.all.disable_ipv6 = 1
- sysctl -w net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6 = 1
The above commands will temporarily disable IPv6, meaning that the settings will not persist after reboot. To re-enable IPv6 reboot your system or execute the above commands again however reverse the logic and change 1 to 0. In case you need more permanent solution to disable IPv6 even after system reboot follow the steps below:
As an administrative user open up the /etc/default/grub file using your favourite text editor and make to following changes: FROM: GRUB_CMDLINE_LINUX_DEFAULT="" TO: GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1"
Once ready update Grub menu: $ sudo update-grub
In case you need to re-enable the IPv6 network addresses simply remove the ipv6.disable=1 from the /etc/default/grub file and run the update-grub command.
