2 thoughts on - CentOS 7.3.1611 – NetworkManager + Dhcp + Ipv6

• IIRC you can disable IPv6 in NetworkManager with:

  # nmcli connection modify eth0 ipv6.method ignore
  # systemctl restart NetworkManager

  or you can disable IPv6 entirely with:

  # vi /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT=”ipv6.disable=1 “

  # grub-mkconfig -o /boot/grub2/grub.cfg
  # reboot

• Hi Patrick,

  I did not disabled on grub or module because of CentOS 7 FAQ
