    Default How to Disable IPv6 in Ubuntu Linux

    Ubuntu has a newer Internet protocol called IPv6 turned on by default. However, some hardware — such as NICs and modems — shows broken behavior when exposed to IPv6 related DNS requests.

    On some connections, the ipv6 kernel module may cause significant slowdowns and fail to connect to IPv6 servers.

    To check if IPv6 is Enabled/Disabled, run the following command in terminal.

    cat /proc/sys/net/ipv6/conf/all/disable_ipv6
    0 means Enabled
    and
    1 means Disabled

    To disable IPv6 in Ubuntu, you have to add the following lines to /etc/sysctl.conf:

    #disable ipv6
    net.ipv6.conf.all.disable_ipv6 = 1
    net.ipv6.conf.default.disable_ipv6 = 1
    net.ipv6.conf.lo.disable_ipv6 = 1
    To do it from the command line, paste this in a terminal:

    echo "#disable ipv6" | sudo tee -a /etc/sysctl.conf
    echo "net.ipv6.conf.all.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
    echo "net.ipv6.conf.default.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
    echo "net.ipv6.conf.lo.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
    Then reboot and check if IPv6 has been disabled with the command

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