IPv6

IPv6 is the most recent version of the Internet Protocol, which identifies computers on networks and routes traffic across the Internet. IPv6 addresses provide more address space than their IPv4 counterparts, and are part of an effort to sustain the growth and deployment of Internet-ready devices. Users may transition to or take advantage of IPv6 in order to stay on the leading edge of future trends.

      How do I disable ipv6 on Ubuntu 20.04

      I have followed every guide to disable ipv6 and yet after EVERY reboot I am still seeing it enabled. How do I disable it? net.ipv6.conf.eth0.disable_ipv6 = 0
      Accepted Answer: Looks like /etc/default/grub.d/50-cloudimg-settings.cfg overrides the GRUB_CMDLINE_LINUX_DEFAULT="console=tty1 console=ttyS0 ipv6.disable=1" line. So set it in that file and then run update-grub.
