This happens on ubuntu18.04 also.

ansible_all_ipv4_addresses that is a list of all ip addresses

[oomichi]

This issue is due to the following Vagrant config ip doesn't work correctly

      ip = "#{$subnet}.#{i+100}"
      node.vm.network :private_network, ip: ip,
        :libvirt__guest_ipv6 => 'yes',
        :libvirt__ipv6_address => "#{$subnet_ipv6}::#{i+100}",
        :libvirt__ipv6_prefix => "64",
        :libvirt__forward_mode => "none",
        :libvirt__dhcp_enabled => false

After rebooting the nuc machine, this issue has been solved.
