在Vagrant中设置的IP不在默认位置

Question

在Windows 10 中使用Vagrant 1.9.2

工作环境使用VPN。

想在Vagrant中指定两个自定义的IP：

Vagrant.configure("2") do |config|                                     
  config.vm.box = "bento/centos-7.3"                                   

  config.vm.provider :virtualbox do |v|                                
    v.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]               
  end                                                                  

  config.vm.define "master", primary: true do |master|                 
    master.vm.network :private_network, ip: "192.168.33.200"           
    master.vm.network :forwarded_port, guest: 22, host: 1234, id: 'ssh'
  end                                                                  

  config.vm.define "node1", autostart: true do |node1|                 
    node1.vm.network :private_network, ip: "192.168.33.201"            
    node1.vm.network :forwarded_port, guest: 22, host: 1235, id: 'ssh' 
  end                                                                  
end

但登陆到master虚拟机时得到以下信息：

[root@localhost ~]# ip a

从node1可以ssh登陆到master:

[root@localhost ~]# ssh vagrant@192.168.33.200

vagrant@192.168.33.200's password:

[vagrant@localhost ~]$

这里的带有自定义IP（192.168.33.200）的enp0s8网络为什么没在默认位置？
即使从Vagrantfile中移除这行：

v.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]

还是一样的结果。
