我有一台 Ubuntu 服务器 (20.04) (SERVER)，正在其上运行 dnsmasq。这台机器的本地 IP 为 SERVERADDRESS
我在同一个网络上有一台 Macbook Pro（客户端）——我更新了 MBP 上的 DNS 规则，使其指向 SERVERADDRESS
我可以在 CLIENT 上 nslookup 任何域，它都能很好地解析。但是，如果我尝试 nslookup SERVERADDRESS，它会说服务器找不到它。此外，它会反向输出，如 SSERDDAREVRES.in-addr.arpa: NXDOMAIN
另外 - 我尝试在 example.com 的服务器上设置自定义域。当我在服务器上运行 nslookup example.com 时，我得到了
Server: 127.0.1.1
Address: 127.0.1.1#53
Name: example.com
Address: 127.0.0.1
正如预期的那样
然而，当我在 CLIENT 上执行同样操作时，我得到了
Server: SERVERADDRESS
Address: SERVERADDRESS#53
Non-authoritative answer:
Name: example.com
Address: 93.184.216.34
这是意料之外的，因为他们应该使用相同的 DNS（服务器）。
我是否需要在客户端上执行其他操作来强制它使用服务器 DNS？
编辑：根据评论添加两台机器的挖掘输出注意：SERVERADDRESS 是本地 IP 地址（192.168。...）在服务器上：
