我有一台 Raspberry Pi 3 Model B（运行 Ubuntu 16.04），我希望能够通过我们公司的内部网以静态 IP 地址访问它。我通过创建一个包含/etc/network/interfaces.d以下内容的文件来实现这一点：
auto enxb827ebf9dfb5
iface enxb827ebf9dfb5 inet static
address 172.16.100.1
netmask 255.255.0.0
gateway 172.16.0.4
dns-nameserver 8.8.8.8
dns-nameserver 8.8.4.4
我的/etc/network/interfaces文件如下所示：
# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
# The loopback network interface
auto lo
iface lo inet loopback
我可以通过这个地址正常连接到我的 RPi。但是，在进行此更改后，我发现它似乎无法正确执行 DNS 解析。例如，我可以通过运行nslookup另一台计算机来 ping Google 以找到其地址之一并ping <that_address>在 RPi 上运行，但ping www.google.com在 RPi 上运行则不起作用。
如果在每次启动后运行，我可以修复 DNS 解析sudo systemctl restart networking，但我希望 DNS 解析能够像配置为使用 DHCP 时一样自动工作。
这是当前的输出ifconfig：
