DisableIPv6onArchLinux.md

To disable IPv6 on Arch Linux:

1. Temporarily (until reboot):

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

2. Persistently (across reboots): Add the following lines to /etc/sysctl.d/99-disable-ipv6.conf:

   net.ipv6.conf.all.disable_ipv6 = 1
   net.ipv6.conf.default.disable_ipv6 = 1
   

   Then run:

   sudo sysctl --system

3. GRUB method (alternative): Add to your /etc/default/grub, line GRUB_CMDLINE_LINUX_DEFAULT, append:

   ipv6.disable=1
   

   Then:

   sudo grub-mkconfig -o /boot/grub/grub.cfg
   sudo reboot
