Fedora 33：使用自定義 DNS 地址

在 Fedora 32 中，我曾經編輯/etc/resolv.conf以修改 DNS 地址：

nameserver [IP1]
nameserver [IP2]

但是在 Fedora 33 中，這個文件已經被改變並且它有一個警告說Do not edit：

# This file is managed by man:systemd-resolved(8). Do not edit.
#
# This is a dynamic resolv.conf file for connecting local clients to the
# internal DNS stub resolver of systemd-resolved. This file lists all
# configured search domains.
#
# Run "resolvectl status" to see details about the uplink DNS servers
# currently in use.
#
# Third party programs should typically not access this file directly, but only
# through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a
# different way, replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

nameserver 127.0.0.53
options edns0 trust-ad

如何修改域名伺服器以便使用自定義 DNS 地址？

resolvectl dns
Global:
Link 2 (enp2s0):
Link 3 (wlp1s0): 192.168.43.63

sudo resolvectl dns wlp1s0 8.8.8.8 4.4.4.4

resolvectl dns
Global:
Link 2 (enp2s0):
Link 3 (wlp1s0): 8.8.8.8 4.4.4.4
