查看 resolv.conf配置发现DNS 服务器是 10.189.128.2

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 directly to

# all known uplink DNS servers. This file lists all configured search domains.

# 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.
