Link 2 (eth0)
      Current Scopes: DNS
       LLMNR setting: yes
MulticastDNS setting: no
      DNSSEC setting: no
    DNSSEC supported: no
         DNS Servers: 192.168.16.2
                      192.168.16.3
          DNS Domain: openstacklocal

我需要更改 eth0 的 DNS。我做了以下操作：

cd /etc/systemd/network
nano 20-wired.network

输入：

[Match]
Name=eth0

[Network]
DNS=1.1.1.1, 192.168.16.2, 192.168.16.3

已保存。

service systemd-networkd restart
service systemd-resolved restart

然后：systemd-resolve --status

什么都没变。我做错了什么？如何更改 eth0 的 DNS？另外：

systemd-resolve --interface eth0 --set-dns 1.1.1.1

输出：

Please configure DNS settings for systemd-networkd managed interfaces directly in their .network files.
