SLAAC won't disable on Ubuntu 17.10

  • 772

I cannot properly disable SLAAC on my Ubuntu 17.10 as there are always 2 dynamic addresses present.

NetworkManager is not installed at all. /etc/network/interfaces only has loopback configured.

Screenshot with configurations

ipv6 17.10

  1. You can try to add

    accept-ra: no

    to your netplan config for the desired interface. According to the manpage of netplan

    man netplan

    this option prevents the kernel from configuring IPv6 by itself on basis of the Router Advertisment sent to your server.
