我在其他局域网设备上的网络很好。但在我的 ubuntu 服务器上，systemd-resolve 总是返回相同的 ip。
例如：
kiddo@nas:~$ nslookup google.com
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:
Name: google.com
Address: 192.168.31.1
kiddo@nas:~$ nslookup facebook.com
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:
Name: facebook.com
Address: 192.168.31.1
使用时也发生过这种情况systemd-resolve。
kiddo@nas:~$ systemd-resolve google.com
google.com: 192.168.31.1 -- link: enp1s0
-- Information acquired via protocol DNS in 32.5ms.
-- Data is authenticated: no
kiddo@nas:~$ systemd-resolve facebook.com
facebook.com: 192.168.31.1 -- link: enp1s0
-- Information acquired via protocol DNS in 27.8ms.
-- Data is authenticated: no
跑步systemd-resolve --status。

192.168.31.1并且fe80::6664:4aff:fe8c:f55c看起来工作正常。
我尝试通过 刷新 DNS 缓存systemd-resolve --flush-caches，但没有帮助。
我尝试过systemd-resolve --reset-server-features并且它有帮助。但是过一段时间问题会再次出现。
在我尝试之后systemd-resolve --reset-server-features。
