linux查看dns命令1:查看/etc/resolv.con文件
[root@localhost ~]# cat /etc/resolv.conf
nameserver 192.168.xxx.xxx
#search localdomain
[root@localhost ~]#
linux查看dns命令2:使用nslookup命令查看DNS信息
[root@localhost ~]# nslookup 127.0.0.1 | grep Server
Server: 192.168.xxx.xxx
[root@localhost ~]#
linux查看dns命令3:使用dig命令来查看DNS信息
root@localhost ~]# dig

在网上看到还有一些其他方法,查看服务器的DNS配置信息,如下所示,不过这些方法,由于环境限制,我没有验证过,仅供参考。
nm-tool | grep DNS
nmcli dev list iface eth0 | grep IP4
