Windows主机是否正确解释了dnsmasq参数？

我有一个由Ubuntu服务器上的dnsmasq实例(Ubuntu 15.10,dnsmasq 2.75)提供服务的 Windows 10计算机网络(DNS和DHCP).设置基本上有效(dnsmasq提供地址并正确管理DNS请求),但一个特定情况除外.

我想为一台特定的机器提供特定的DNS服务器.我在dnsmasq中使用了tag选项：

# open zone
dhcp-host=84:3a:4b:20:94:f0,set:open

# DNS for everyone = OpenDNS
dhcp-option-force=option:dns-server,208.67.222.222,208.67.220.220
# DNS for open = Google
dhcp-option-force=tag:open,option:dns-server,8.8.8.8,8.8.4.4

在客户端上进行ipconfig / renew时,dnsmasq会发送正确的选项：

因此,客户端被赋予IP 10.10.10.21(我在测试期间更改了它,并且每次都分配了正确的一个,每次更改 – 因此客户端正确解释了对请求的响应),以及特定的DNS服务器.

从dnsmasqside看起来一切都很好看.

在客户端我得到

我在客户端检查了Wireshark收到的流量.在DHCP ACK数据包(从DHCP服务器中获取的数据包)中,该选项是正确的(因此它没有被删除或类似的东西)：

IP是正常但DNS服务器不正确：它默认为DH??CP服务器 – 看起来接收的选项没有正确解释(？)
