前段時間，我偶然進行檢視linux DNS配置，通過檢視 /etc/resolv.conf 檔案，得到如下結果：

➜  devices ll /etc/resolv.conf
lrwxrwxrwx 1 root root 39 12月 28 18:55 /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf
➜  devices cat /etc/resolv.conf
# 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 must 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
